Key Features
- LVDS differential output clock fanout with low skew enables synchronous distribution across multiple high-speed ICs
- Differential mux input accepts multiple clock sources and selects between them without external glue logic
- 16-pin VQFN package provides compact 3.3V clock distribution in space-constrained telecom and networking PCB designs
Applications
The SY89876LMG-TR is used in high-speed synchronous digital systems where a single reference clock must be divided and distributed to multiple devices with minimal skew, such as Ethernet switch ASICs, FPGA clock trees, and backplane clock distribution networks. The LVDS differential outputs reduce susceptibility to common-mode noise on long PCB traces and across board-to-board connectors in telecom line cards. Its differential mux input also enables seamless clock source switchover for redundancy in carrier-grade equipment.

Frequently Asked Questions
What output interface standard does the SY89876LMG-TR use and why is that important for high-speed PCB clock distribution?
The SY89876LMG-TR uses LVDS (Low Voltage Differential Signaling) outputs, which transmit clock signals as differential pairs with a small 350mV swing at 3.3V supply. LVDS outputs reject common-mode noise picked up along PCB traces, enabling reliable clock distribution at frequencies above 100 MHz across multiple receiving devices while keeping output-to-output skew low enough for synchronous designs in networking and telecom equipment.
How does the differential mux input of the SY89876LMG-TR support clock redundancy in a carrier-grade system?
The differential mux input on the SY89876LMG-TR allows the designer to feed 2 clock sources into the device and select between them via a control signal. In a carrier-grade line card or switch fabric, this supports hitless or glitch-controlled clock source switchover when the primary reference fails, maintaining system timing continuity without requiring an external discrete mux IC ahead of the fanout buffer.
What lead time should buyers plan for when procuring the SY89876LMG-TR for a production build?
The SY89876LMG-TR has a factory lead time of approximately 8 weeks from Microchip. For production builds, buyers should place orders at least 8 weeks before the scheduled assembly start date and consider stocking buffer inventory for the VQFN-16 package variant. Tape-and-reel (-TR) packaging is standard for pick-and-place automated PCB assembly, which is the typical procurement format for volume orders.
