DESCRIPTION

The IR3Y48M is a CMOS single-chip signal

processing IC for CCD area sensors which includes

correlated double sampling circuit (CDS), clamp

circuit, automatic gain control amplifier (AGC),

reference voltage generator, black level detection

circuit, 20 MHz 10-bit analog-to-digital converter

(ADC), timing circuit for internally required pulses,

and serial interface for internal circuits.

FEATURES

• Low power consumption :

110 mW (TYP.) at 20 MHz mode

• Wide AGC range : 0 to 36 dB

(Gain step : 0.094 dB/step)

• High speed sample-and-hold circuits :

pulse width 10 ns (MIN.)

• Power save operation :

84 mW (TYP.) at 15 MHz mode

• Standby mode : less than 0.3 mW

• Built-in serial interface

• 10-bit ADC operating up to 20 MHz

– Non-linearity

DNL : 0.6 LSB (TYP.)

INL : 1.5 LSB (TYP.)

• Maximum input level of CCD signals : 1.1 Vp-p

• Accepts a direct signal input to ADC or AGC

(input level : 1 Vp-p (TYP.))

• Single +3 V power supply

• Package :

48-pin QFP (QFP048-P-0707) 0.5 mm pin-pitch
