WRT2/IQSEL GENERAL DESCRIPTION
The AD9763/AD9765/AD9767 are dual-port, high speed,
2-channel, 10-/12-/14-bit CMOS DACs. Each part integrates
two high quality TxDAC+В® cores, a voltage reference, and digital
interface circuitry into a small 48-lead LQFP. The AD9763/
AD9765/AD9767 offer exceptional ac and dc performance
while supporting update rates of up to 125 MSPS.
The AD9763/AD9765/AD9767 have been optimized for
processing I and Q data in communications applications. The
digital interface consists of two double-buffered latches as well
as control logic. Separate write inputs allow data to be written to …
