GENERAL DESCRIPTION
The AD9901 is a digital phase/frequency discriminator capable of directly comparing phase/frequency inputs up to 200 MHz. Processing in a high speed trench-oxide isolated process, combined with an innovative design, gives the AD9901 a linear detection range, free of indeterminate phase detection zones common to other digital designs.
FEATURES
Phase and Frequency Detection
ECL/TTL/CMOS Compatible
Linear Transfer Function
No “Dead Zone”
MIL-STD-883 Compliant Versions Available
APPLICATIONS
Low Phase Noise Reference Loops
Fast-Tuning “Agile” IF Loops
Secure “Hopping” Communications
Coherent Radar Transmitter/Receiver Chains
