What is SI5341A-D-GMR used for?
SI5341A-D-GMR is used in optical networking line cards, 5G base station timing modules, and high-speed data converter clocking where ultra-low jitter and flexible output frequencies up to 1028 MHz are critical. It also suits FPGA system clocking, Ethernet synchronization equipment, and telecom timing cards requiring hitless reference switching and multi-output clock distribution from a single 64-pin QFN device.

Frequently Asked Questions
What input frequency range does SI5341A-D-GMR accept and how many outputs can it drive simultaneously?
SI5341A-D-GMR accepts any reference input from 10 MHz to 750 MHz and can drive up to 10 independent outputs at frequencies up to 1028 MHz. This wide input range makes it compatible with standard XO, TCXO, and network synchronization sources used in 5G and optical networking equipment.
How does the integrated DSPLL in SI5341A-D-GMR benefit systems that require hitless clock switching?
The SI5341A-D-GMR integrates a Digital Phase-Locked Loop (DSPLL) that enables hitless switching between up to 4 reference inputs without output glitches. In telecom timing applications, this means a 1028 MHz output can survive a reference failover — from a GPS-synchronized 10 MHz input to a local oscillator — without disrupting downstream framer or SERDES circuits.
What output signal formats does SI5341A-D-GMR support, and how does this affect PCB design?
SI5341A-D-GMR supports LVDS, LVPECL, HCSL, and LVCMOS output formats, selectable per output. LVDS and LVPECL outputs typically require 100-ohm differential termination at the load, while HCSL supports PCIe and Ethernet clocking standards. Mixing output formats on the 10 outputs lets engineers drive multiple interface standards from a single 64-pin QFN, reducing chip count and PCB space.
For a 5G RRU timing board, why would SI5341A-D-GMR be chosen over a simpler PLL clock synthesizer?
5G Radio Remote Units require sub-100 fs RMS jitter and the ability to lock to multiple reference standards simultaneously. SI5341A-D-GMR provides 10 flexible outputs from 10 MHz to 1028 MHz, hitless reference switching, and ultra-low phase noise from a single 64-pin QFN — features that a basic PLL synthesizer with only 1-4 outputs and fixed-ratio dividers cannot match in a compact footprint.
