Ultrahigh Speed
Phase/Frequency Discriminator
AD9901
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, com-
bined with an innovative design, gives the AD9901 a linear
detection range, free of indeterminate phase detection zones
common to other digital designs.
With a single +5 V supply, the AD9901 can be configured to
operate with TTL or CMOS logic levels; it can also operate
with ECL inputs when operated with a –5.2 V supply. The
open-collector outputs allow the output swing to be matched to
post-filtering input requirements. A simple current setting resis-
tor controls the output stage current range, permitting a reduc-
tion in power when operated at lower frequencies.
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
A major feature of the AD9901 is its ability to compare
phase/frequency inputs at standard IF frequencies without
prescalers. Excessive phase uncertainty which is common with
standard PLL configurations is also eliminated. The AD9901
provides the locking speed of traditional phase/frequency dis-
criminators, with the phase stability of analog mixers.
The AD9901 is available as a commercial temperature range
device, 0
°
C to +70
°
C, and as a military temperature device,
–55
°
C to +125
°
C. The commercial versions are packaged in a
14-lead ceramic DIP and a 20-lead PLCC.
The AD9901 Phase/Frequency Discriminator is available in
versions compliant with MIL-STD-883. Refer to the Analog
