CXD2303AQ

CXD2303AQ 8-bit 3-channel 50 MSPS Video A/D Converter with clamp function Description The CXD2303AQ is an 8-bit 3-channel CMOS A/D converter for video with synchronizing digital clamp function. The adoption of 2 step-parallel method achieves low power consumption and a maximum conversion rates of 50 MSPS. Features Resolution : 8 bit±1/2 LSB (DL) Maximum sampling frequency : 50 MSPS Low power consumption : 400 mW (at 50 MSPS Typ.) (Reference current excluded) Synchronizing digital clamp function Clamp ON/OFF function Reference voltage self-bias circuit Input CMOS/TTL compatible 3-state TTL compatible output Single 5 V power supply or dual 5 V/3.3 V power supplies Low input capacitance 15 pF Reference impedance : 370 Ω (Typ.) Different digital output multiplex format: – 4 : 4 : 4 format – 4 : 2 : 2 format – 4 : 1 : 1 format Applications Wide range of applications that require high-speed A/D conversion such as monitor, TV and VCR.
