AD9901 Overview
The AD9901 is a digital phase/frequency discriminator capable of directly paring phase/frequency inputs up to 200 MHz. Processing in a high speed trench-oxide isolated process, bined with an innovative design, gives the AD9901 a linear detection range, free of indeterminate phase detection zones mon to other digital designs. With a single +5 V supply, the AD9901 can be configured to operate with TTL or CMOS logic...
