2002 may 22 7 philips semiconductors product speci?cation low power audio dac UDA1334BT 8 functional description 8.1 system clock the UDA1334BT operates in slave mode only; this means that in all applications the system must provide the system clock and the digital audio interface signals (bck and ws). the system clock must be locked in frequency to the digital interface signals. the UDA1334BT automatically detects the ratio between the sysclk and ws frequencies. the bck clock can be up to 64f s , or in other words the bck frequency is 64 times the word select (ws) frequency or less: f bck 64 f ws . remarks: 1. the ws edge must fall on the negative edge of the bck at all times for proper operation of the digital i/o data interface 2. for lsb-justified formats it is important to have a ws signal with a duty factor of 50%. the modes which are supported are given in table 1. table 1 supported sampling ranges notes 1. this mode can only be supported for power supply voltages down to 2.4 v. for lower voltages, in 192f s mode the sampling frequency should be limited to 55 khz. 2. not supported in the low sampling frequency mode. an example is given in table 2 for a 12.228 mhz system clock input. table 2 example using a 12.228 mhz system clock note 1. this mode can only be supported for power supply voltages down to 2.4 v. for lower voltages, in 192f s mode the sampling frequency should be limited to 55 khz. 8.2 interpolation ?lter the interpolation digital filter interpolates from 1f s to 64f s by cascading fir filters (see table 3). table 3 interpolation ?lter characteristics 8.3 noise shaper the 5th-order noise shaper operates at 64f s . it shifts in-band quantization noise to frequencies well above the audio band. this noise shaping technique enables high signal-to-noise ratios to be achieved. the noise shaper output is converted into an analog signal using a filter stream dac (fsdac). clock mode sampling range 768f s 8to55khz 512f s 8 to 100 khz 384f s 8 to 100 khz 256f s 8 to 100 khz 192f s 8 to 100 khz (1)(2) 128f s 8 to 100 khz (2) clock mode sampling frequency 128f s 96 khz 192f s 64 khz (1) 256f s 48 khz 384f s 32 khz 512f s 24 khz 768f s 16 khz item condition value (db) pass-band ripple 0 to 0.45f s 0.02 stop band >0.55f s - 50 dynamic range 0 to 0.45f s >114
2002 may 22 8 philips semiconductors product speci?cation low power audio dac UDA1334BT 8.4 filter stream dac the fsdac is a semi-digital reconstruction filter that converts the 1-bit data stream of the noise shaper to an analog output voltage. the filter coefficients are implemented as current sources and are summed at virtual ground of the output operational amplifier. in this way very high signal-to-noise performance and low clock jitter sensitivity is achieved. no post-filter is needed due to the inherent filter function of the dac. on-board amplifiers convert the fsdac output current to an output voltage signal capable of driving a line output. the output voltage of the fsdac scales proportionally with the power supply voltage. 8.5 power-on reset the UDA1334BT has an internal power-on reset circuit (see fig.3) which resets the test control block. the reset time (see fig.4) is determined by an external capacitor which is connected between pin v ref(dac) and ground. the reset time should be at least 1 m s for v ref(dac) < 1.25 v. when v dda is switched off, the device will be reset again for v ref(dac) < 0.75 v. during the reset time the system clock should be running. handbook, halfpage v dda v ref(dac) 3.0 v 13 12 mgu678 UDA1334BT c1 > 10 m f reset circuit 50 k w 50 k w fig.3 power-on reset circuit. handbook, halfpage 3.0 v ddd (v) 1.5 0 t 3.0 v dda (v) 1.5 0 t 3.0 v ref(dac) (v) 1.5 1.25 0.75 0 t mgl984 > 1 m s fig.4 power-on reset timing.

2002 may 22 18 philips semiconductors product speci?cation low power audio dac UDA1334BT 17 soldering 17.1 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. 17.2 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. 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 250 c. the top-surface temperature of the packages should preferable be kept below 220 c for thick/large packages, and below 235 c for small/thin packages. 17.3 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 is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 17.4 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.
