LZ93B53
Synchronous Signal Generator for CCD
DESCRIPTION
The LZ93B53 is a CMOS synchronous signal
generator LSI which provides B/W TV synchro-
nous pulses and video signal processing pulses,
in combination with the timing signal generator
LSI (LZ93N61, LZ95F50, or LZ93F33).
FEATURES
. Switchable between 270000 pixels B/W CCD
and 320000 pixels B/W CCD
. Switchable between EIA and CCIR systems
q Single + 5 V power supply
. External synchronization is possible
. Package : f 8-pin MFP(MFPOI 8-P)
