Product Summary
The CXA3026Q 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. Applications of the CXA3026Q are (1)magnetic recording (PRML); (2)communications (QPSK, QAM); (3)LCDs; (4)digital oscilloscopes.
