CX20052A

The CX20052A is a kind of serial-parallel type high speed A/D converter with a resolution of 8-bit for processing video signals driven by a single -5.0 V power source. It performs an A/D conversion of vide signals with an external sample and holding circuit. A reference voltage and a clock should be added external to it.

There are some features of CX20052A as follows: (1)maximum sampling frequency of 20 MHz (min); (2)low power consumption 700 mW (typ); (3)non-linearity error ±1/2 LSB; (4)-5.0 V single power supply; (5)both clock input and digital output are in ECL level.

The following is about the absolute maximum ratings of CX20052A (Ta=25): (1)supply voltage, VEE: -9.0 V; (2)clock voltage, VCLK: VEE to +0.3 V; (3)input signal voltage, VIN: VEE to +0.3 V; (4)reference voltage, VREF: VEE to +0.3 V; (5)digital output current, IOH: 10 mA; (6)operating temperature, Topr: -10 to +70; (7)storage temperature, Tstg: -50 to +150; (8)allowable power dissipation, PD: 1.47 W.
