(2) , for all global tv standards (pal, ntsc and secam). it is used together with the picture improvement processor saa4978h and saa4979h. the SAA4998H is an advanced version of the saa4993h. by embedding the field memories it reduces the part count of the realized concept from 4 to 6 parts to only 2 parts and reduces the package size from a qfp160 to a qfp100. the full falconic mode uses full motion estimation and motion compensation on 1 / 4 pixel accuracy to perform frame rate upconversion film mode detection movie judder cancellation dynamic noise reduction (dnr) edge dependent de-interlacing (eddi). the motion compensated de-interlacer is improved with a new patented edge dependent de-interlacing (eddi) method. this avoids jagged edges of diagonal lines. the better de-interlacer leads to a significant better performance of progressive as well as interlaced output formats. a 60 hz progressive output frame rate can be generated for 50 hz pal sources to enable the use of 60 hz lcd or pdp panels in pal regions. 50 hz interlaced to 75 hz interlaced and 60 hz interlaced to 90 hz interlaced can be generated to achieve an increased number of lines and hence a reduction of line visibility for jumbo screens and ptv applications. the embedded memory can be used to synchronize the main channel and the 2nd channel for pip and double window applications. this avoids to add additional buffer memory devices to the application. for demonstration purposes a split screen mode to show the dynamic noise reduction (dnr) function, natural motion, and eddi is available. the estimated motion vectors can be made visible by colour overlay mode. the SAA4998H supports a boundary scan test (bst) circuit in accordance with ieee std. 1149.1 . (1) eddi is protected with two patents of koninklijke philips electronics n.v. (2) natural motion is a trademark of koninklijke philips electronics n.v.

2004 feb 18 10 philips semiconductors product speci?cation field and line rate converter with noise reduction and embedded memory SAA4998H notes 1. not used input pins should be connected to ground. 2. because of the noisy characteristic of the supply voltage of output pads (v dde ), it is recommended not to connect v dde directly at the high supply voltage of the intern field memories (v ddp ). all pins v dde should be buffered as close as possible to the device. v ddp needs a low noise supply voltage, therefore, it is recommended that v ddp has to be separated from v dde by an external filter structure. because of the high working frequency of the device, it is also recommended to filter the core supply voltage (v ddd ). all pins v ddd should be buffered as close as possible to the device. 3. v ssd , v ssm and v sss are connected internally. 4. ref rising edge must be after rising edge of snrst in order to be detected. v ddm 98 supply supply voltage of the internal ?eld memories (1.8 v) v ssm 99 ground ?eld memory ground yg6/dpip6 100 output/input pip mode disabled: bus g luminance output bit 6; pip mode enabled: pip data input bit 6 symbol pin type description (1)(2)(3)

2004 feb 18 36 philips semiconductors product speci?cation field and line rate converter with noise reduction and embedded memory SAA4998H 12 soldering 12.1 introduction to soldering surface mount packages this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering can still be used for certain surface mount ics, but it is not suitable for fine pitch smds. in these situations reflow soldering is recommended. 12.2 re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 270 c depending on solder paste material. the top-surface temperature of the packages should preferably be kept: below 225 c (snpb process) or below 245 c (pb-free process) C for all bga, htsson-t and ssop-t packages C for packages with a thickness 3 2.5 mm C for packages with a thickness < 2.5 mm and a volume 3 350 mm 3 so called thick/large packages. below 240 c (snpb process) or below 260 c (pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm 3 so called small/thin packages. moisture sensitivity precautions, as indicated on packing, must be respected at all times. 12.3 wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 c or 265 c, depending on solder material applied, snpb or pb-free respectively. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 12.4 manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
2004 feb 18 37 philips semiconductors product speci?cation field and line rate converter with noise reduction and embedded memory SAA4998H 12.5 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. for more detailed information on the bga packages refer to the (lf)bga application note (an01026); order a copy from your philips semiconductors sales office. 2. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 3. these transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 c 10 c measured in the atmosphere of the reflow oven. the package body peak temperature must be kept as low as possible. 4. these packages are not suitable for wave soldering. on versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. on versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 5. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 6. wave soldering is suitable for lqfp, tqfp and qfp packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 7. wave soldering is suitable for ssop, tssop, vso and vssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. 8. image sensor packages in principle should not be soldered. they are mounted in sockets or delivered pre-mounted on flex foil. however, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. the appropriate soldering profile can be provided on request. 9. hot bar or manual soldering is suitable for pmfp packages. 12.6 additional soldering information the package qfp100 (lead-free; sot317gc11, subpackage of the sot317-2) is granted the moisture sensitivity level (msl) 3. soldering temperature of > 215 c is recommended or rma flux. package (1) soldering method wave reflow (2) bga, htsson..t (3) , lbga, lfbga, sqfp, ssop..t (3) , tfbga, uson, vfbga not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hso, hsop, hsqfp, hsson, htqfp, htssop, hvqfn, hvson, sms not suitable (4) suitable plcc (5) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (5)(6) suitable ssop, tssop, vso, vssop not recommended (7) suitable cwqccn..l (8) , pmfp (9) , wqccn..l (8) not suitable not suitable
