SY58052AUMG - 10.7Gbps CML Clock Synchronizer | Microchip
MPN： SY58052AUMG ✓ 啟用中SY58052AUMG 概覽
A data-to-clock resynchronizer is a timing device that reconstructs a clean clock or data edge from a jittery serial data stream by aligning it to a clean reference clock. Within the signal-chain hierarchy, it sits between a clock-and-timing IC and the physical-layer transceivers it serves, forming part of the broader family of PLLs, clock synthesizers, and jitter cleaners used in high-speed serial links. Retiming restores eye diagrams degraded by backplane loss and crosstalk, preventing jitter accumulation across a system.
Key features include guaranteed AC performance over temperature and voltage with DC-to-greater-than-10.7Gbps data-rate throughput and DC-to-greater-than-10.7GHz clock fMAX, a 160ps maximum any-input-to-any-output propagation window, and resynchronization of data to a reference clock. The Precision Edge(R) family device accepts CML, PECL, and data-type inputs and delivers CML outputs, easing interface design in mixed signaling environments.
The SY58052AU architecture performs edge realignment internally with input and output termination integrated on-chip, reducing external component count and improving signal integrity at multi-gigabit rates. Because the resynchronizer acts as a jitter filter, downstream receivers see a wider eye opening, directly improving bit-error-rate margins in long serial links.
Typical applications include backplane retiming, retiming after data transmission over lossy media, 10G Ethernet and SONET/SDH-style serial links, and test-and-measurement instrumentation front ends. The -40C to +85C operating range and 2.375V to 3.63V supply suit telecom and datacom infrastructure equipment.
For design, verify the reference-clock jitter budget: the output jitter of the SY58052AU is bounded by the reference clock quality, so use a low-noise crystal oscillator at the CLK input. Keep CML output trace impedances at 50 ohms single-ended to ground-referenced termination.

典型應用
SY58052AUMG 適用於 6 應用s: Backplane Retiming, 10G Ethernet Links, Telecommunications Infrastructure, Test and Measurement Equipment, Data Center Switching, Clock Distribution Cleanup.
Backplane Retiming
The SY58052AUMG fits backplane retiming because high-speed serial signals traversing long backplane traces accumulate deterministic and random jitter that erodes the receiver eye. By resynchronizing data edges to a clean reference clock at up to 10.7Gbps, the device acts as a jitter filter, regenerating clean transitions before the signal reaches the far-end receiver. Placed at a mid-span or card-entry point with its integrated input/output termination, it typically restores significant eye margin without external termination components. The 160ps maximum any-input-to-any-output delay is deterministic and low enough for most latency budgets, making it a drop-in retiming element in 10G-class chassis designs.

10G Ethernet Links
For 10GBASE-R serial links running at 10.3125Gbps, the SY58052AUMG's guaranteed DC-to-10.7Gbps throughput covers the line rate with margin. The CML-compatible inputs and outputs, with internal termination, connect directly to typical 10G PHY and SerDes I/O without level-shifting networks. Retiming the serial stream before it enters the optical module or crosses a copper interconnect reduces the jitter budget consumed by the link, improving bit-error-rate headroom. The -40C to +85C operating range supports outdoor and uncooled equipment. Designers should supply a low-noise reference clock, since output jitter is bounded by reference quality.

Telecommunications Infrastructure
Telecom line cards and transport equipment operating near OC-192 rates (approximately 10Gbps) benefit from the SY58052AUMG's 10.7Gbps maximum clock support and industrial temperature range of -40C to +85C. The device retimes data recovered from long-haul or metro transport paths, realigning it to the system reference clock before further processing. Its 2.375V to 3.63V supply accepts standard 2.5V or 3.3V card rails with adequate decoupling. Because the AC performance is guaranteed over temperature and voltage, timing margins hold across worst-case field conditions, which is critical for carrier-grade availability targets and BER objectives in telecom equipment.
推薦
Test and Measurement Equipment
In bit-error-rate testers, oscilloscope timing references, and pattern generators, the SY58052AUMG provides clean edge regeneration at data rates up to 10.7Gbps. Its 160ps maximum input-to-output delay is tightly specified, which matters when instrument timing channels must be phase-predictable. CML outputs with on-chip termination drive 50-ohm environments directly, and CML/PECL input flexibility lets one instrument design accept multiple signal standards. The Precision Edge(R) family's guaranteed AC performance over voltage and temperature ensures measurement repeatability as instruments warm up, supporting laboratory-grade accuracy requirements in high-speed serial test applications.
推薦
Data Center Switching
Data-center switch and router line cards move 10G-class SerDes traffic between switch fabric and cage interfaces across lossy PCB materials. Inserting the SY58052AUMG as a retimer at the card edge cleans jitter accumulated in long traces and vias, widening the eye presented to optical modules and improving link budget margins. The 3x3 mm 16-VFQFN exposed-pad package minimizes board area in dense designs, and the integrated terminations reduce the BOM. With a 2.375V to 3.63V supply range, the part operates directly from common card power rails. Deterministic 160ps maximum delay simplifies latency accounting across fabric paths.
推薦
Clock Distribution Cleanup
Beyond data retiming, the SY58052AUMG synchronizes clock signals up to 10.7GHz, regenerating clean copies of distribution clocks that have degraded after long fanout paths or lossy media. Systems that distribute a master timing reference across shelves can place this device at each shelf entry to restore edge sharpness before local clock trees. CML outputs with internal termination drive downstream dividers or PLLs directly. Because the device resynchronizes to a reference clock, output edges are phase-locked to the intended timing source rather than merely buffered, eliminating accumulated phase drift - a key advantage over simple CML fanout buffers in precision timing chains.

設計說明
Solder the exposed pad of the 16-VFQFN to a continuous ground plane with a dense via array (recommended 4x4 or better) directly under the pad. At 10.7GHz, ground return inductance dominates CML edge quality and jitter; a thermally-relieved or single-via pad connection will degrade performance. Keep CML input and output traces as 50-ohm single-ended (100-ohm differential) controlled impedance, length-matched within a few mils, and avoid stubs or test points on these nets.
Output jitter of the SY58052AUMG is bounded by the quality of the reference clock applied to the CLK input. Use a low-phase-noise crystal oscillator (XO) rather than a free-running RC oscillator, and route the reference clock away from switching regulators. Because AC performance is guaranteed over voltage and temperature per the datasheet, verify that local supply decoupling (100nF ceramic per supply pin plus bulk 10uF) keeps ripple within the 2.375V to 3.63V window during SerDes switching transients.
Do not treat this part as a simple buffer: it requires a valid reference clock to resynchronize data, and without one the output will not be a retimed signal. Confirm the reference clock frequency matches the intended serial line rate before layout freeze. Also note the 160ps figure is the maximum any-input-to-any-output delay, not propagation through a single channel - budget latency accordingly in loop-timing designs.
