Product details

Active PLL synthesizer for RF local-oscillator generation

The ADF4118BRUZ-RL is a PLL-based clock/frequency synthesizer (RF) from Analog Devices, designed to generate local-oscillator signals up to 3 GHz. It accepts CMOS or TTL reference inputs and outputs a single clock. The 2:1 input-to-output ratio allows selecting between two reference sources.

3 GHz ceiling and wide supply range

The 3 GHz maximum frequency suits it for synthesizing LO signals in wireless infrastructure, test equipment, and satellite downconverters. The supply range of 2.7V to 5.5V lets it run from a 3.3V or 5V rail without an extra regulator — a clean fit for mixed-voltage boards. Compared to the ADF4111BRUZ-RL7, which tops out at 1.4 GHz, the ADF4118BRUZ-RL covers higher-frequency bands. The ADF4112BRUZ-REEL7 also reaches 3 GHz and is a pin-compatible alternative with a different divider ratio set — check the N-divider range if you need a specific frequency step size.

16-TSSOP: hand-rework and layout notes

The 16-TSSOP package has a 0.173 inch body width — the narrow footprint keeps the layout compact.

Frequently asked questions

What is the maximum frequency of the ADF4118BRUZ-RL?

3 GHz. That is the upper limit for the RF input; the PLL divider and phase detector can operate at lower frequencies depending on the reference input.

Does the ADF4118BRUZ-RL have a direct replacement or equivalent?

The ADF4112BRUZ-REEL7 is a pin-compatible sibling also rated to 3 GHz, with a different N-divider range. The ADF4111BRUZ-RL7 is limited to 1.4 GHz. Confirm the divider ratio and frequency step requirements before substituting.
