Description
The CXD1176Q is an 8-bit CMOS A/D converter
for video use that features a sync clamp function. The
adoption of a 2 step-parallel method realizes low
power consumption and a maximum conversion
speed of 20MSPS.
Features
Resolution power: 8-bit ± 1/2LSB (DL)
Maximum sampling frequency: 20MSPS
Low power consumption: 60mW (at 20MSPS typ.)
(Reference current excluded)
Built-in sync type clamp function
Built-in monostable multivibrator for clamp pulse
generation
Built-in sync pulse polarity selection function
Clamp pulse direct input possible
Built-in clamp ON/OFF function
Built-in reference voltage self-bias circuit
Input CMOS compatible
3-state TTL compatible output
Single 5 V power supply
Low input capacity: 11 pF
Reference impedance: 330
(typ.)
Applications
TV and VCR digital systems and a wide range of
applications where high-speed A/D conversion is
required.
