| LSIs for Video MN673794 Digital Conversion IC s Overview The MN673794 accepts an analog video signal in the NTSC or PAL format and converts it to an ITU-R BT.656 signal, the standard signal for digital video signal transmission. s Features * Increased calculation precision for Y/C separation (both 2D and 3D): 9 bits. * Processing from A/D conversion through Rec. 656 output can be performed with a single fixed 27 MHz clock. * Velocity error correction has been introduced in the TBC (Time Base Corrector), to create a correct time axis across the whole screen. * Supports signal standardization using a frame synchronizer. * Use of embedded DRAM allows all the above functions to be implemented on a single chip. Item Functions DD conversion processing, frame synchronization processing Analog inputs Digital I/O Operating frequency Supply voltage im Two systems: composite video signal and separate Y and C signals One ITU-R BT.656 system Operates at up to 27 MHz 3.3 V 0.3 V (analog input block) el Pr Package s Applications * DVD recorders, hard disk application products, multimedia PCs, and display equipment such as TVs and PDPs. in 208 pin LQFP (28 mm Motion adaptive 3D Y/C separation, TBC processing, 3D noise reduction processing, 1.8V 0.15 V (internal digital blocks) 2.5 V 0.2 V (internal DRAM block) , 0.5 mm lead pitch) ar y MN673794 Publication date: January 2002 SDB00082AEM 1 MN673794 s Block Diagram DRAM (5Mbit) SEL CLK27XO CLK27XI RST Clock generator ANACLK CLK27O R656IN 7 to 0 CLK27I 8 Rec. 656 input signal S E L ar y S E L S E L Rec. 656 output processing Noise reduction Microcontroller I/F MICONRWW MICONRWR MICOMSEL NC3 Frame synchronization R656OUT 7 to 0 Analog input processing 2D/3D Y/C separation VIDEO A/D 10bit 27MHz LPF 6MHz Digital clamp Copyright protection detection APCE CSYNCO GCP CLPOS AGCO ACCO CIN D/A D/A D/A A/D 10bit 27MHz Microcontroller im S E L Analog system control in APC MDA15 to 0 MAD6 to 0 MNWENBW MNRE MCSALE DD conversion Sync separator circuit LPF 6MHz Chroma decoder ACC 2 Pr SDB00082AEM el Line TBC/DD conversion DRAM (7Mbit) DD conversion MN673794 s Pin Assignment M IM CN CC M MM MM V MM MM DD D DD V DD AA DAA S AA 01 3 23S 45 V MM M MV D DDD VD DD A DA A SA A D 1 I 6 7 S8 9 3 0 D MM MM MMMM D D V DD A VA A DAA VA A A A 1 S 1 1 D 1 1 SDDDD 1S2 3 I 45 S0 1 2 3 LL V MM M V 2 D A A AV D 7 D D D DS D X 3 4 5 6S I O KK OW C M ME S F I DN NAV SN RN DC RLS EB PF I 3 ES LW E C DSO O 2 D D NV N VR 7 R R RDR SS X A A WD W ST I MMR3W M VV I DSC M I 207 205 203 201 199 197 195 193 191 189 187 185 183 181 179 177 175 173 171 169 167 165 163 161 159 157 208 206 204 202 200 198 196 194 192 190 188 186 184 182 180 178 176 174 172 170 168 166 164 162 160 158 CLK18O2 VDD3 CLK45I VSS VDDI DSF7 DSF6 VSS DSF5 DSF4 VDD2 DSF3 DSF2 VSS DSF1 DSF0 VDD2 CASHD CASVD VSS CLK188 CLK450 VDD2 CLK18O1 VSS AVSS1 TPLL AVDD1 AVSS1 VREFCK IREFCK COMPCK CK45O AVDD1 AVSS1 VREFC IREFC COMPC OUTC AVDD1 AVSS1 VREFY IREFY COMPY OUTY AVDD1 AGCO AVSS1 CLPOS VREFMA AVDD1 ACCO 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 156 155 154 153 152 151 150 149 148 147 146 145 144 143 142 141 140 139 138 137 136 135 134 133 132 131 130 129 128 127 126 125 124 123 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 CSYNCO VSS APCE VDD3 VD HD VSS VDDI R656OUT0 R656OUT1 VSS R656OUT2 R656OUT3 VDD3 R656OUT4 R656OUT5 VSS R656OUT6 R656OUT7 VDDI CLK27O VSS R656IN0 R656IN1 VDD3 R656IN2 R656IN3 VSSDRAM VDDDRAM VSS R656IN4 R656IN5 VDD3 R656IN6 R656IN7 VSS CLK27I VDDI VSS NTDRAM VDDDRAM VSSDRAM PDRAM1 PDRAM0 VDD3 MINTEST MINTIN1 MINTC1 VSS VDDI TEST0 TEST1 Pr 1 C L C MC C C 54 56 58 60 62 64 66 68 70 72 74 76 78 80 82 84 86 88 90 92 94 96 98 100 102 104 53 55 57 59 61 63 65 67 69 71 73 75 77 79 81 83 85 87 89 91 93 95 97 99 101 103 A C A V V V V V AA A VA V V V V VA A VA V GTT V T TV TT V V I V R R R R R V V V I V R R R R RV V S N D C E E S E E D E E S D N S E E E E E S D D D S E E E E ES D S A D P S S S S S D S S S T T I TT S F F F F F S D D ES F F F F F S D C 3 D TT 1 L M MH H 1 1 1 O 1 L MM H H 1 1 YL YMY Y Y L K II OO 98 II OO 76 II OO 54 el V V T T V T T V T TV T T TV D S E E D E E S C D D D R MS D S S S D S S SK OD I S S S DD T T 3 T T I T RR I I II AA OO MM 3 2 OO 10 TT TT EE EE SS SS TT TT 54 32 im SDB00082AEM in ar y 3 MN673794 s Pin Descriptions Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 Pin Name CLK18O2 VDD3 CLK45I VSS VDD1 DSF7 DSF6 VSS DSF5 DSF4 VDD2 DSF3 DSF2 VSS DSF1 DSF0 VDD2 CASHD CASVH VSS CLK188 CLK450 VDD2 CLK18O1 VSS AVSS1 TPLL AVDD1 AVSS2 I/O O Power supply Voltage 3.3V 3.3V 1.8V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V 2.2V Clock: 18 MHz, 2 outputs Digital I/O system (3.3 V) Description I GND Power supply Clock: 4.5 MHz input (Connect to VSS if unused.)
