SPT7755
8-BIT, 750 MSPS, FLASH A/D CONVERTER
OCTOBER 2002
FEATURES
• • • • • • 1:2 Demuxed ECL compatible outputs Wide input bandwidth – 900 MHz Low input capacitance – 15 pF Metastable errors reduced to 1 LSB Monolithic for low cost Gray code output
APPLICATIONS
• • • • Digital oscilloscopes Transient capture Radar, EW, ECM Direct RF down-conversion
GENERAL DESCRIPTION
The SPT7755 is a full parallel (flash) analog-to-digital converter capable of digitizing full scale (0 to –2 V) inputs into eight-bit digital words at an update rate of 750 MSPS. The ECL-compatible outputs are demultiplexed into two separate output banks, each with differential data ready outputs to ease the task of data capture.
