DESCRIPTION
RES
1
reserved pin; do not connect
SP
2
I
test pin; connected to digital ground for normal operation
AP
3
I
test pin; connected to digital ground for normal operation
LLC1
4
I
line-locked clock input; this is the 27 MHz master clock
VSSD1
5
supply digital ground 1
VDDD1
6
supply digital supply voltage 1
RCV1
7
I/O
raster control 1 for video port; this pin receives/provides a VS/FS/FSEQ signal
RCV2
8
I/O
raster control 2 for video port; this pin provides an HS pulse of programmable length or
receives an HS pulse
MP7
9
I
double-speed 54 MHz MPEG port; it is an input for
“ITU-R BT.656” style multiplexed
CB-Y-CR data; data is sampled on the rising and falling clock edge; data sampled on the
rising edge is then sent to the encoding part of the device; data sampled on the falling
edge is sent to the RGB part of the device (or vice versa, depending on programming)

supply digital ground 2
RTCI
19
I
real-time control input; if the LLC1 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
VDD(I2C)
20
supply sense input for I2C-bus voltage; connect to I2C-bus supply
SA
21
I
select I2C-bus address; LOW selects slave address 88H, HIGH selects slave address
8CH

22
supply analog ground 1 for RED (CR), C (CVBS) and GREEN (Y) outputs
RED
23
O
analog output of RED (CR) signal
C
24
O
analog output of chrominance (CVBS) signal
VDDA1
25
supply analog supply voltage 1 for RED (CR) and C (CVBS) outputs
GREEN
26
O
analog output of GREEN (Y) signal
VBS
27
O
analog output of VBS (CVBS) signal
VDDA2
28
supply analog supply voltage 2 for VBS (CVBS) and GREEN (Y) outputs
BLUE
29
O
analog output of BLUE (CB) signal
CVBS
30
O
analog output of CVBS (CSYNC) signal
VDDA3
31
supply analog supply voltage 3 for BLUE (CB) and CVBS (CSYNC) outputs
VSSA2
32
supply analog ground 2 for VBS (CVBS), BLUE (CB) and CVBS (CSYNC) outputs
VSSA3
33
supply analog ground 3 for the DAC reference ladder and the oscillator
XTALO
34
O
crystal oscillator output
XTALI
35
I
crystal oscillator input; if the oscillator is not used, this pin should be connected to ground
VDDA4
36
supply analog supply voltage 4 for the DAC reference ladder and the oscillator
