1 / 21 page  TVP3703 VIDEO INTERFACE PALETTE TRUE-COLOR CMOS RAMDAC SLAS100 – MARCH 1996 Copyright © 1996, Texas Instruments Incorporated 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 • Fully Integrated Dual Clock Synthesizer and 16-Bit Pixel Port True-Color RAMDAC • Two Phase-Locked-Loop (PLL) Synthesizers Provide Independently Controlled Video and Memory Clock Outputs • Functionally Interchangeable with STG1703 • On-Chip PLL Clock Reference Requires Single External Crystal • 16-Bit Pixel Port Supports VGA High-Color and True-Color Standards Up to 170 MHz • Programmable Power-Down Features • On-Chip Cyclic Redundancy Check (CRC) Test description The TVP3703 is a super video graphics array (SVGA) compatible, true-color CMOS RAMDAC with integrated clock synthesizers that can provide the memory and pixel clock signals for a PC graphics subsystem. The video clock can be one of two VGA base frequencies or fourteen Video Electronics Standards Association (VESA) standard frequencies which can also be reprogrammed through the standard micro port interface. The memory clock output is also user programmable at frequencies up to 80 MHz. The pixel modes supported by the TVP3703 include: • Serializing 16-bit pixel port providing 170 MHz, 8-bit and 73 MHz, 24-bit packed pixel modes using an internal PLL • 16-bit pixel port providing faster, high-color/true-color operation up to the 110 MHz sampling rate • 8-bit pixel port providing standard SVGA and high-color/true-color modes up to the 110 MHz sampling rate The 68 terminal FN package is designed to be interchangeable with the STG1703. 28 29 GND P7 P6 P5 P4 P3 P2 P1 P0 REF RS2 COMP RSET VS3 VS2 VS1 VS0 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 30 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 GND BLANK D0 D1 D2 D3 D4 D5 D6 D7 WR RS0 RS1 P14 PIXMIX P15 NC 31 32 33 34 FN PACKAGE (TOP VIEW) 87 6 5 4 93 168 67 2 35 36 37 38 39 66 65 27 64 63 62 61 40 41 42 43 NC – No internal connection PRODUCTION DATA information is current as of publication date.
