SI5332D-D-GM2R

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5332D-D-GM2R is a low-jitter, 8-output programmable clock generator from Skyworks Solutions. It utilizes MultiSynth technology to generate integer frequencies up to 200 MHz with zero ppm synthesis error. The device supports external crystal inputs (16–50 MHz) or differential/LVCMOS clock inputs. Outputs are configurable as LVDS, LVPECL, HCSL, or LVCMOS across independent voltage banks (1.5 V to 3.3 V). Key electrical parameters include a phase jitter of 190 fs RMS and an operating temperature range of –40 °C to +85 °C. It is housed in a 40-pin QFN package.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific NVM code assigned by ClockBuilder Pro, as the base part number requires configuration data for operation. Confirm package type matches design requirements; GM2 denotes the 40-pin QFN variant. Ensure I2C interface compatibility with the host controller for any dynamic configuration needs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for designs requiring up to eight differential outputs with mixed voltage levels. The 'D' suffix indicates integer-only mode capability up to 200 MHz. For fractional synthesis or higher frequencies up to 333.33 MHz, consider Si5332A, C, E, G, or L variants. Verify input source availability (external crystal vs. clock) against the selected grade specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5332 family of any-frequency clock generators. The GM2 suffix specifically identifies the 40-pin package supporting up to eight outputs. Other family members include GM1 (32-pin, 6 outputs) and GM3 (48-pin, 12 outputs), offering scalability for different output density requirements within the same architectural framework.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same package require matching the output count and voltage domains. Variants like SI5332B-D-GM2R offer similar integer capabilities but may differ in specific electrical characteristics or feature sets. Always validate register maps and timing parameters when substituting.
