IR3Y48M
IR3Y48M
CCD Signal Process & Digital Interface IC
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
