Key Features
- 3.2 Gbps LVDS signaling support enabling direct use in high-speed serial data distribution and clock tree designs
- Fail-safe input (FSI) feature ensuring outputs default to a known state when inputs are open or undriven, preventing system lockup
- Low-skew dual LVDS outputs for tight timing budgets in clock distribution networks and high-speed synchronous logic
- Compact 8-pin VDFN package minimizing PCB footprint in space-constrained high-frequency layout applications
Applications
SY58605UMG-TR is used in high-speed clock distribution networks for networking switch ASICs, FPGAs, and SerDes devices where 3.2 Gbps low-skew LVDS fanout is required. Its fail-safe input is valuable in hot-swap and backplane systems where input signals may be momentarily absent during board insertion. The device also suits clock multiplexing and signal conditioning in telecom line cards and data center switching equipment.

Frequently Asked Questions
What is the maximum signaling rate of SY58605UMG-TR and how does it fit into a 10 GbE clock distribution architecture?
SY58605UMG-TR supports data rates up to 3.2 Gbps, which covers common reference clock rates such as 156.25 MHz (for 10 GbE) when used as a low-skew LVDS buffer. It fans out a single clock source to 2 differential outputs with minimal added jitter, making it suitable as a clock tree element feeding SERDES PLLs in 10 GbE switch designs.
What does the fail-safe input (FSI) feature do and when is it important?
The fail-safe input ensures that SY58605UMG-TR outputs default to a defined logic state when the differential input pair is open-circuit or floating, rather than oscillating or driving indeterminate levels. This is critical in hot-swap backplane designs and multi-board systems where input connections may be momentarily broken during board insertion, preventing false clocking of downstream 3.2 Gbps logic.
How does the 8-pin VDFN package of SY58605UMG-TR help in high-frequency PCB layouts?
The VDFN-8 package has an exposed thermal pad and very short lead lengths, reducing parasitic inductance and improving ground return paths at 3.2 Gbps operation. The compact footprint allows placement within 5 mm of source and load devices, minimizing stub lengths and maintaining signal integrity on high-speed differential pairs routed at controlled 100-ohm impedance.
Can SY58605UMG-TR replace a standard LVDS repeater in a 1.5 Gbps SATA clock distribution path?
Yes. SY58605UMG-TR's 3.2 Gbps rated input supports 1.5 Gbps SATA reference clock signals well within its bandwidth. The 2 LVDS outputs with low output skew allow a single 150 MHz SATA reference to fan out to 2 independent receivers while maintaining the sub-100 ps skew budget required for reliable SATA data link synchronization.
