DESCRIPTION
CCD Signal Process & Digital Interface IC
PIN CONNECTIONS
48-PIN QFP
TOP VIEW
The IR3Y48A1 is a CMOS single-chip signal
processing IC for CCD area sensors which includes
correlated double sampling circuit (CDS), clamp
circuit, programmable gain amplifier (PGA),
reference voltage generator, black level detection
circuit, 18 MHz 10-bit analog-to-digital converter
(ADC), timing generator for internally required
pulses, and serial interface for internal function
control and PGA gain control.
