Description

The CXA1166K is an 8-bit ultrahigh-speed flash A/D converter IC capable of digitizing analog signals at a maximum rate of 250 MSPS. The digital I/O level of this A/D converter is compatible with the ECL 100K/10KH/10K.

This IC is pin-compatible with the conventional CXA1076AK/CXA1176K/CXA1176AK, and can replace the conventional models easily. Compared with the conventional models, the CXA1166K has a greatly improved performance because of the new circuit design and carefully considered layout.
