Product details

4 GHz fractional-N PLL with LVDS/LVPECL inputs

The ADF4155BCPZ-RL7 is a PLL-based fractional-N frequency synthesizer from Analog Devices, capable of generating output clocks up to 4 GHz. The single-circuit PLL integrates a divider and multiplier, so the output frequency can be set with fine resolution from a stable reference. The 2:1 input-to-output ratio allows selecting between two reference sources without external muxing.

Active production – sourcing posture

Sourced per RFQ against your BOM quantity.

Package and footprint notes

Housed in a 24-lead LFCSP (4x4 mm) with an exposed pad. Store the reels in a dry cabinet or use a moisture-barrier bag with desiccant.

Frequently asked questions

What is the maximum output frequency of ADF4155BCPZ-RL7?

The maximum output frequency is 4 GHz. This covers common RF bands including 2.4 GHz ISM, 3.5 GHz WiMAX, and C-band satellite downlinks.

Does ADF4155BCPZ-RL7 accept LVDS inputs?

Yes, the reference input accepts both LVDS and LVPECL differential signals. The input is differential; the output is single-ended.

What is the closest functional alternative to ADF4155BCPZ-RL7?

The ADF4156BRUZ-RL7 also reaches 6.2 GHz but in a different package (TSSOP). Neither is a drop-in replacement — verify pinout and output type before substituting.
