SI5345D-B04600-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5345D-B04600-GMR is a 10-channel jitter attenuator and clock multiplier from the Si5345 Rev D family. It supports integer-only frequency synthesis with output frequencies ranging from 0.001 MHz to 350 MHz. The device features four inputs (differential or LVCMOS) and ten configurable outputs compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL standards. It operates on a 1.8 V core voltage and 3.3 V I/O supply within a temperature range of -40°C to +85°C. Packaged in a 64-QFN (9x9 mm), it includes an integrated loop filter and non-volatile memory for configuration storage.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm factory preprogramming details. Confirm package availability and lead times through authorized distributors. Ensure compliance with RoHS-6 standards and verify humidity sensitivity handling requirements during assembly.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when integer-only synthesis is sufficient for the application, as it differs from the fractional-capable Si5345A. Verify that the required output frequency range does not exceed 350 MHz. Ensure the design accommodates the 64-QFN footprint and utilizes ClockBuilder Pro software for optimal configuration and register mapping.
