| Symbol | Pin Name | Description |
| VDD1 | Logic power supply | 2.7 t0 3.6 V |
| VDD2 | Driver power supply | 7.0 t0 10.5 V |
| VSS1 | Logic ground | Ground(0 V) |
| VSS2 | Driver ground | Ground(0 V) |
| Y1 to Y420 | Driver outputs | The D/A converted 64 gray-scale analog voltage is output. |
| DOP<0:2> DON<0:2> DIP<0:2> DIN<0:2> D2P<0:2> D2N<0:2> | RSDS data input | Total data lines consist of 18 data bus. (6-bit digital, 3 colors (R, G, B) and 2 differential input pairs) The 3 - bit differential input pairs generate the internal 6 - bit data through the comparison between DxxP and DxxN. |
| SHL | Shift direction control input | This pin controls the direction of shift register in cascade connection. When SHL = H: Dl01 input, Y1} Y420, D102 0utput When SHL = L: D102 input, Y420} Y1, Dl01 0utput |
| Dl01 | Start pulse input/ output | SHL = H: Used as the start pulse input pin. SHL = L: Used as the start pulse output pin. |
| D102 | Start pulse input/ output | SHL = H: Used as the start pulse output pin. SHL = L: Used as the start pulse input pin. |
| DATPOL | Data inversion input | DATPOL = L: No inversion DATPOL = H: Data polarity inversion (HL) |
| POL | Polarity input | POL = H: The reference voltage for odd number outputs are VGMAl to VGMA5 and those for even number outputs are VGMA6 to VGMA10. POL = L: The reference voltage for odd number outputs are VGMA6 to VGMA10 and those for even number outputs are VGMAl to VGMA5. |
| CLKP CLKN | RSDS shift clock input | The RSDS clock input pairs generate the internal shift clock, CLK2, through the comparison between CLKP and CLKN. |
| CLK1 | Latch input | S6C0679 clears 140 shift registers at the rising edge of CLKl and outputs the analog data to the each channel at the falling edge. |
| VGMA1 to VGMA10 | Gamma corrected power supplies | Input the gamma corrected power supplies from external source. VDD2 > VGMAl > VGMA2 > ...... > VGMA9 > VGMA10 > VSS2 Keep power supplies unchanged during the gray-scale voltage output. |
| RPIl, RP01 RP12, RP02 | Line-repair AMP input / output | The Structure of the line-repair amp is the same as that of the analog output. RPIl (RP12)} impedance changed} RP01 (RP02) |
| TEST | Test input | TEST = L: Normal operation mode TEST = H: Test mode (OP AMP CUT-OFF, Rpd = 15 kQ) |

UHF MODULATED OUTPUT Modulation and relative levels of vision and sound carrier levels are preset for the selected broadcast standard. Table 2 gives the output options available. Modulation index is fixed at 83% for all negative modulation systems and at 94% for SECAM standard L. Selection of sound tank frequency is defined by off-chip tank components.
