4 / 40 page  1996 Jul 08 4 Philips Semiconductors Preliminary specification Digital Video Encoder (EURO-DENC) SAA7182; SAA7183 PINNING SYMBOL PIN DESCRIPTION RESET 1 Reset input, active LOW. After reset is applied, all digital I/Os are in input mode. The I2C-bus receiver waits for the START condition. n.c. 2 not connected VSSD1 3 digital ground 1 SA 4 The I2C-bus slave address select pin. LOW: slave address = 88H, HIGH = 8CH. VDDD1 5 digital supply voltage 1 OVL2 6 3-bit overlay data input. This is the index for the internal look-up table. OVL1 7 OVL0 8 KEY 9 Key input for OVL. When HIGH it selects OVL input. DP0 10 Lower 4 bits of the data port. Input for multiplexed Cb, Cr data if 16 line input mode is used. DP1 11 DP2 12 DP3 13 VDDD2 14 digital supply voltage 2 VSSD2 15 digital ground 2 DP4 16 Upper 4 bits of the data port. Input for multiplexed Cb, Cr data if 16 line input mode is used. DP5 17 DP6 18 DP7 19 TTXRQ 20 Teletext request output, indicating when the bitstream is valid. TTX 21 Teletext bitstream input. VDDD3 22 digital supply voltage 3 n.c. 23 not connected VSSD3 24 digital ground 3 MP7 25 Upper 4 bits of MPEG port. It is an input for “CCIR 656” style multiplexed Cb, Y, Cr data, or input for Y data only, if 16 line input mode is used. MP6 26 MP5 27 MP4 28 VDDD4 29 digital supply voltage 4 VSSD4 30 digital ground 4 MP3 31 Lower 4 bits of MPEG port. It is an input for “CCIR 656” style multiplexed Cb, Y, Cr data, or input for Y data only, if 16 line input mode is used. MP2 32 MP1 33 MP0 34 RCV1 35 Raster Control 1 for video port. This pin receives/provides a VS/FS/FSEQ signal. RCV2 36 Raster Control 2 for video port. This pin provides an HS pulse of programmable length or receives an HS pulse. RTCI 37 Real Time Control Input. If the LLC clock is provided by an SAA7111 or SAA7151B, RTCI should be connected to the RTCO pin of the respective decoder to improve the signal quality. |
