The AD9901KP is a high-speed digital phase/frequency discriminator designed for phase-locked loop (PLL) applications. It operates at frequencies up to 200 MHz and accepts CMOS, ECL, and TTL input logic levels. The device features differential inputs and outputs with a 2:1 input-to-output ratio, providing a linear detection range with no dead zone. This eliminates phase uncertainty common in standard PLL configurations.
The discriminator operates from a single 5 V supply and uses open-collector outputs that allow the output swing to be matched to post-filtering requirements. A current setting resistor controls the output stage current range, enabling power reduction at lower frequencies. The AD9901KP is housed in a 20-lead PLCC (J-Lead) surface mount package measuring 9x9 mm.
Typical applications include low phase noise reference loops, fast-tuning agile IF loops, secure hopping communications, and coherent radar transmitter/receiver chains. The device is available in commercial (0°C to +70°C) and military (-55°C to +125°C) temperature ranges, though the specific range for this part number should be verified from the datasheet.
