CXA3256R

CXA3256R 8-bit 120MSPS Flash A/D Converter Description The CXA3256R is an 8-bit high-speed flash A/D converter capable of digitizing analog signals at the maximum rate of 120MSPS. ECL, PECL or TTL can be selected as the digital input level in accordance with the application. The TTL digital output level allows 1: 2 demultiplexed output. The CXA3256R is easier to be used by adding the new functions to the CXA3246Q and adopting a ultra-small package. Features Differential linearity error: ±0.5LSB or less Integral linearity error: ±0.5LSB or less High-speed operation with a maximum conversion rate of 120MSPS Low input capacitance: 10pF Wide analog input bandwidth: 250MHz Low power consumption: 500mW Power saving function 1: 2 demultiplexed output 1/2 frequency-divided clock output (with reset function) Compatible with ECL, PECL and TTL digital input levels TTL output "H" levels: 2.8V (Typ.)
