DESCRIPTION
reserved
test pin; connected to digital ground for normal operation
test pin; connected to digital ground for normal operation
line-locked clock; this is the 27 MHz master clock for the encoder
digital ground 1
digital supply voltage 1
raster control 1 for video port; this pin receives/provides a VS/FS/FSEQ signal
raster control 2 for video port; this pin provides an HS pulse of programmable
length or receives an HS pulse
MPEG ports; inputs for “CCIR 656” style multiplexed C_B-Y-C_R data
digital supply voltage 2
digital ground 2
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
reserved
the I²C-bus slave address select input pin; LOW: slave address = 88H,
HIGH = 8CH
reserved
reserved
analog output of the chrominance signal
analog supply voltage 1 for the C DAC
reserved
analog output of VBS signal
analog supply voltage 2 for the Y DAC
reserved
analog output of the CVBS signal
analog supply voltage 3 for the CVBS DAC
analog ground 1 for the DACs
analog ground 2 for the oscillator and reference voltage
crystal oscillator output
crystal oscillator input; if the oscillator is not used, this pin should be connected to
ground
analog supply voltage 4 for the oscillator and reference voltage
