What are the key features of SY58028UMG?
- 4:1 differential CML input multiplexer supporting multi-GHz signal routing with precision matched propagation delays for low-jitter clock and data switching
- Dual-supply compatibility operating at both 3.3 V and 5 V rails enabling flexible integration across SONET, Ethernet, and test equipment backplanes
- Compact 32-pin MLF (VQFN) package with low thermal resistance enabling high-frequency differential signal multiplexing in space-constrained line-card PCB designs
What is SY58028UMG used for?
SY58028UMG is used in high-speed data center switches, optical transport network line cards, and multi-channel SerDes test platforms where 4 differential CML signal sources must be routed to a single output channel. Its precision multiplexer design minimizes added jitter, making it suitable for OC-192 SONET and 10 Gbps Ethernet clock distribution networks. The 32-pin MLF package integrates all 4 input channels and control logic, reducing PCB layer count and signal path length for high-frequency designs.

Frequently Asked Questions
What input configuration does SY58028UMG support and at what data rates does it operate?
SY58028UMG is a 4:1 differential CML multiplexer capable of routing 4 high-speed differential input signals to a single output at multi-GHz data rates supporting protocols such as 10 Gbps Ethernet and OC-192 SONET. The differential CML interface provides low-jitter signal switching with matched propagation paths across all 4 input channels in the 32-pin MLF package.
Can SY58028UMG operate from a 3.3 V supply, and what does dual-supply compatibility mean for system design?
SY58028UMG operates at both 3.3 V and 5 V supply voltages as noted in its additional features. Dual-supply compatibility allows the same 32-pin VQFN device to be used in modern 3.3 V digital line cards and legacy 5 V backplanes, reducing the number of qualified component variants that system designers must maintain for multi-generation optical transport equipment.
For a SerDes test platform requiring 4 clock sources to be selected, why is SY58028UMG preferred over discrete CML gate-based multiplexers?
SY58028UMG integrates precision-matched 4:1 differential CML multiplexing in a single 32-pin MLF package, ensuring consistent delay matching across all 4 input paths that discrete CML gates cannot guarantee without careful layout. The single-device solution reduces PCB trace mismatch and eliminates 8 to 12 discrete termination resistors, saving board area and maintaining differential signal integrity at multi-GHz switching speeds in test equipment designs.
