PL602031UMG-TR

Clock Generators, PLLs, Frequency Synthesizers Overview

The PL602031UMG-TR is a high-performance, low-power HCSL-compatible clock generator designed for PCI Express applications. It features two differential outputs operating at 50MHz (derived from a 25MHz fundamental input) with very low jitter of 2ps TIE RMS and -130dBc phase noise at 10kHz offset. The device operates within a supply voltage range of 2.25V to 3.63V and supports an ambient temperature range of -40°C to +85°C. Packaged in a compact 16-pin QFN format, it integrates internal AC coupling and includes output enable pins for power management.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the manufacturer origin as Micrel, Inc., noting that Microchip Technology acquired Micrel's assets. Confirm the package type is 16-pin QFN (3mm x 3mm) and ensure the suffix 'TR' indicates tape and reel shipping. Check RoHS and PFOS compliance status for environmental requirements.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the PL602031 variant specifically when a 50MHz differential output is required from a 25MHz source. Consider the PL60203X series if higher frequencies like 100MHz or 125MHz are needed. Ensure PCB layout guidelines for HCSL termination and crystal placement are followed to maintain specified jitter performance.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the PL60203X family of HCSL-compatible clock generators. Other members include PL602032 (100MHz), PL602033 (125MHz), and PL602034 (200MHz). All share the same 16-pin QFN package and general electrical characteristics, differing primarily in output frequency multiplication ratios.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include PL602032UMG-TR, PL602033UMG-TR, and PL602034UMG-TR, provided the target application can accommodate their respective output frequencies of 100MHz, 125MHz, and 200MHz.
