PLL synthesizer with phase detector for RF clock generation
The ADF4002SRUZ-EP-RL7 is a PLL-based clock/frequency synthesizer (RF) combined with a phase detector, designed for generating stable RF clocks from a reference input. It accepts CMOS, TTL, or crystal inputs and outputs CMOS-level signals, making it a flexible building block for frequency synthesis in communications and instrumentation. With a 2:1 input-to-output ratio and a single circuit, this IC is suited for applications requiring a clean, phase-locked clock derived from a lower-frequency reference. The integrated phase detector allows direct comparison of the feedback and reference signals, simplifying loop filter design.
Extended temperature grade for harsh environments
This makes the ADF4002SRUZ-EP-RL7 a fit for avionics, downhole drilling, military communications, and other applications where the ambient temperature swings beyond the industrial range. Compared to the ADF4001BRUZ-R7, which operates up to 200 MHz and has a -40°C to 85°C range, this part offers a wider temperature envelope and PLL functionality for higher-frequency synthesis. The ADF4106BRUZ-R7 reaches 6 GHz but also lacks the extended temperature rating.
Active lifecycle and compliance status
Supplied in Tape & Reel (TR) or Cut Tape (CT) options, the 16-TSSOP package is surface-mount and hand-solderable with a fine-tip iron or hot-air station — the 0.65 mm pitch is manageable for a skilled hobbyist or repair technician.
Supply voltage and input flexibility
Operating from 2.7V to 3.3V, this PLL can run directly off a 3.3V rail or a 2.7V battery supply without an extra regulator. The input accepts CMOS, TTL, or crystal sources, so it can lock to a standard TCXO or a logic-level reference clock. The differential input and output are supported (Yes/No), enabling use with differential reference sources if needed. The single-circuit design keeps the BOM simple for point-to-point frequency synthesis.
