V385A 8-BIT LVDS TRANSMITTER FOR VIDEO General Description Features The V385A transmitter converts 28 bits of 3.3 V CMOS/TTL into 4 Low Voltage Differential Signaling (LVDS) data streams while the transmit clock input is transmitted in parallel with the data streams over a fifth LVDS link. • Extended clock frequency range of 12 to 90 MHz • Pin and function compatible with the National Compared to the V385, the V385A provides an extended clock frequency range of 12-90 MHz, rather than 20-85 MHz. Other performance improvements have been incorporated as well. • Convert 28 bits of 3.3 V CMOS/TTL into 4 LVDS The V385A can be programmed for rising edge or falling edge clocks through pin R_FB. • • • • • • • • • • Pin Assignment VCC TxIN5 TxIN6 TxIN7 GND TxIN8 TxIN9 TxIN10 VCC TxIN11 TxIN12 TxIN13 GND TxIN14 TxIN15 TxIN16 R_FB TxIN17 TxIN18 TxIN19 GND TxIN20 TxIN21 TxIN22 TxIN23 VCC TxIN24 TxIN25 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 56 55 54 53 52 51 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 TxIN4 TxIN3 TxIN2 GND TxIN1 TxIN0 TxIN27 LVDS_GND TxOUT0TxOUT0+ TxOUT1TxOUT1+ LVDS_VCC LVDS_GND TxOUT2TxOUT2+ TxCLKOUTTxCLKOUT+ TxOUT3TxOUT3+ LVDS_GND PLL_GND PLL_VCC PLL_GND PWRDWN TxCLKIN TxIN26 GND DS90C385, TI SN65LVDS93 and THine THC63LVDM83, but with extended clock frequency and operating temperature range streams • Up to 2.52 Gbps throughput or 315 Megabytes/sec bandwidth Spread spectrum compatible Supports SD, HD and VGA graphics applications LVDS voltage swing of 350 mV for low EMI On-chip PLL requires no external components Single 3.3 V low-power CMOS design Operating temperature of 0 to +70°C Programmable rising or falling edge strobe Power-down control function Compatible with TIA/EIA-644 LVDS standards Packaged in a 56-pin TSSOP (Pb free available) Block Diagram Red, Green, Blue TxOUT0+ 24 TxOUT0- HSYNC TxOUT1+ VSYNC DATA ENABLE TxOUT1- TTL to LVDS TxOUT2+ CONTROL TxOUT2R_FB TxOUT3+ PWRDWN TxOUT3TxCLKOUT+ CLOCK PLL TxCLKOUT- 56-pin TSSOP V385A Datasheet 1 11/23/05 Revision 0.1 I n t e g r a t e d C i r c u i t S y s t e m s • 5 2 5 R a c e St r e e t , S a n J o s e , C A 9 5 1 2 6 • t e l ( 4 0 8) 2 97 - 1 2 0 1 • w ww. i c s t . co m V385A 8-BIT LVDS TRANSMITTER FOR VIDEO Pin Descriptions Pin Pin Type Pin Name Pin Description/Name 1 Power VCC 3.3V Power 2 CMOS/TTL TxIN5 Parallel digital video input pins (TxIN0..27). 3 CMOS/TTL TxIn6 Parallel digital video input pins (TxIN0..27). 4 CMOS/TTL TxIn7 Parallel digital video input pins (TxIN0..27). 5 Ground GND Ground 6 CMOS/TTL TxIN8 Parallel digital video input pins (TxIN0..27). 7 CMOS/TTL TxIN9 Parallel digital video input pins (TxIN0..27). 8 CMOS/TTL TxIN10 Parallel digital video input pins (TxIN0..27). 9 Power VCC 3.3V Power 10 CMOS/TTL TxIN11 Parallel digital video input pins (TxIN0..27). 11 CMOS/TTL TxIN12 Parallel digital video input pins (TxIN0..27). 12 CMOS/TTL TxIN13 Parallel digital video input pins (TxIN0..27). 13 Ground GND Ground 14 CMOS/TTL TxIN14 Parallel digital video input pins (TxIN0..27). 15 CMOS/TTL TxIN15 Parallel digital video input pins (TxIN0..27). 16 CMOS/TTL TxIN16 Parallel digital video input pins (TxIN0..27). 17 CMOS/TTL R_FB Programmable strobe select input pin (R_FB).
