GENERAL DESCRIPTION
The AD99SS is a 100 MHz direct digital synthesizer for fre-
quency synthesis applications. It comprises a 32-bit phase accu-
mulator and a IS-bit phase-to-12-bit sine amplitude converter.
The control logic is CMOS compatible, and the clock input is
TTL. CMOS outputs are latched on board, and a data ready
signal is provided.
Designed for applications in communications, instrumentation,
and military systems, the AD99SS can be combined with a clock
reference and a DAC such as the AD97l3B or AD9721 to form
a digitally-controlled analog frequency reference.
The AD99SS is available in an SO-leadplastic quad flatpack
(PQFP) for commercial (O°Cto + 70°C) temperature range appli-
cations. Contact the factory for information concerning the avail-
ability of a military temperature range device.
