Product details

What the AD9542BCPZ does on the board

The AD9542BCPZ is a dual-PLL clock synthesizer from Analog Devices that generates a clean, low-jitter output clock up to 2.415 GHz from a variety of input references — CMOS, differential, single-ended, LVDS, or LVPECL. Its 4:5 input-to-output ratio and two independent PLL circuits make it suited for multi-frequency clock trees in communications infrastructure, instrumentation, and data-converter clocking.

Parametric deep-dive: frequency, supply, and signal flexibility

The 2.415 GHz maximum output frequency covers RF and IF clock synthesis for ADCs, DACs, and mixers up into the low microwave band. The dual supply — a 1.71V–1.89V core rail and a separate 1.71V–3.465V I/O rail — lets the output buffers swing at the logic level of the downstream device without extra translation. Output options include CML, CMOS, HCSL, and LVDS, so the same part can drive a serializer, an FPGA reference clock, or a data converter sample clock.

Package and footprint: 48-LFCSP with exposed pad

The 48-LFCSP (7x7) package is a surface-mount, quad-flat no-lead with an exposed thermal pad.

Frequently asked questions

Does AD9542BCPZ support CML output?

Yes, the AD9542BCPZ output options include CML, along with CMOS, HCSL, and LVDS — covering the common interface standards for high-speed clock distribution.

What is the closest functional equivalent to AD9542BCPZ?

The AD9542BCPZ-REEL7 is the same silicon in tape-and-reel packaging — electrically identical. For a different feature set, the AD9544BCPZ-REEL7 is a clock synchronizer with 2.4 GHz max frequency and 4:10 input-to-output ratio, but without the divider/multiplier function.
