SY58052AUMG-TR 概要
A data-clock synchronizer, also called a retimer, is a high-speed interface IC that regenerates a clean clock from an incoming serial data stream, or resynchronizes data to a reference clock, removing accumulated jitter. Within the signal-chain hierarchy it sits between serializers/deserializers (SerDes), backplane drivers, and clock distribution ICs, and is a critical building block of physical-layer (PHY) conditioning in high-speed serial links.
Key features include differential CML inputs with a unique internal termination network accessible through a VT pin, differential CML outputs, and operation from a 2.375 V to 3.63 V supply over the industrial temperature range of -40C to +85C. The internal terminations allow direct interfacing to multiple logic standards, both AC-coupled and DC-coupled, without external resistor-bias or termination networks.
Technically, the VT-pin architecture produces a clean, stub-free, low-jitter input interface: termination is realized on-chip, eliminating the parasitic stubs and impedance discontinuities that external discrete termination networks introduce. The CML output stage drives 50-ohm differential transmission lines directly, preserving signal integrity at multi-gigabit data rates on FR-4 backplanes and copper cable assemblies.
Typical applications include backplane retiming in telecom and data-communication equipment, retiming after long data transmission in ATM/SONET/SDH systems, and jitter cleanup in 10G serial links, where the part restores data-edge alignment ahead of a SerDes or clock-recovery module.
Design consideration: the exposed pad is the main ground and thermal path, so it must be soldered to a solid ground plane with an array of vias; leaving it floating degrades return-loss and jitter performance.

主な用途
SY58052AUMG-TR の用途: 6 件s: Backplane Retiming, ATM/SONET/SDH Transport Systems, Jitter Cleanup in 10G Serial Links, High-Speed Test and Measurement Equipment, Optical Module Retiming, Industrial High-Speed Interconnect.
Backplane Retiming
In telecom and data-center chassis, serial links traverse long FR-4 backplane traces that accumulate deterministic and random jitter. The SY58052AUMG-TR is explicitly positioned by Microchip as an ideal solution for backplane retiming: its guaranteed 10.7 Gbps throughput covers 10G-class backplane channels, while the internal input termination accessed through the VT pin provides a clean, stub-free interface to the received differential pair. Placed at the card edge or mid-span, the retimer regenerates data edges ahead of the downstream SerDes, extending the jitter budget of the overall link. Because no external bias resistors are needed, multi-channel cards save layout area on dense 3x3 mm footprints.
おすすめ
ATM/SONET/SDH Transport Systems
ATM/SONET/SDH transport equipment classifies the SY58052AUMG-TR as a support circuit: it resynchronizes recovered serial streams (e.g., OC-192 / STM-64 class payloads) after long-haul transmission. The part's industrial -40C to +85C operating range matches central-office and outside-plant card environments, and its 2.375 V to 3.63 V supply covers standard 2.5 V and 3.3 V card rails. The differential CML output directly drives 50-ohm transmission lines toward the framer/deserializer, preserving eye margin. Internal terminations remove the discrete bias networks that historically occupied framer-card area, simplifying the receive path of high-port-count transport shelves.

Jitter Cleanup in 10G Serial Links
Ahead of clock-and-data-recovery (CDR) modules, the SY58052AUMG-TR acts as a jitter-cleanup stage: incoming data edges contaminated by cable, connector, and trace impairments are re-synchronized to the local reference, producing a low-jitter output. The 10.7 Gbps maximum data rate leaves headroom above 10.3125 GbE line rates. Because both input and output terminations are internal, AC-coupled links between different logic standards (CML, LVPECL drivers) interface directly, with the VT pin adapting the input bias. Designers typically AC-couple with 100 nF series capacitors and keep differential pairs at 100 ohms odd-mode impedance for best results.
おすすめ
High-Speed Test and Measurement Equipment
BERT (bit-error-ratio) testers, protocol analyzers, and oscilloscope front ends benefit from the SY58052AUMG-TR's ultra-precision, low-jitter resynchronization at up to 10.7 GHz. In instrumentation, the data-to-clock resynchronizer recovers a clean clock from the stimulus data stream, ensuring measurement timing references do not add systematic jitter. The 3x3 mm VFQFN enables compact probe-head and fixture designs where real estate is constrained, and the industrial temperature range supports bench-to-field portability. The stub-free internal-termination input is particularly valuable in fixtures, where every external component adds an uncalibrated reflection that corrupts high-rate measurements.
おすすめ
Optical Module Retiming
In XFP/SFP+ class optical transceiver applications, the SY58052AUMG-TR can retime the electrical retimed signal between the laser driver/limiting-amplifier section and the host SerDes. Its 10.7 Gbps rating matches 10G optical line rates, and its CML I/O levels align with typical limiting-amplifier outputs. The compact 3x3 mm exposed-pad package fits within the strict module height and area budget, while operation from a single 2.5 V or 3.3 V module rail simplifies power-tree design. The internal termination eliminates discrete bias components on the crowded module PCB, where every mm2 counts and stub parasitics directly degrade the transmit/receive eye.
おすすめ
Industrial High-Speed Interconnect
Factory automation and machine-vision systems increasingly use multi-gigabit serial camera and sensor links. The SY58052AUMG-TR's industrial -40C to +85C temperature grade makes it suitable for these environments, where cable runs between cameras, frame grabbers, and controllers inject jitter that a retimer can remove before the host link layer. The wide 2.375 V to 3.63 V supply tolerance accommodates noisy industrial power rails, and the no-lead QFN package withstands vibration better than fine-pitch leaded packages. Its VT-pin adaptability lets the same board design interface to different camera-link serializer output standards without BOM changes.

設計ノート
The exposed pad of the 16-VFQFN is the primary ground return for this 10.7 GHz CML device. Create a land pattern matching the datasheet mechanical drawing, connect the pad to a solid ground plane through a 3x3 (or denser) via array, and ensure the pad paste coverage is 50-80% to avoid voiding. All sixteen no-lead terminals plus the pad should be soldered; X-ray or 2D/3D AOI inspection is recommended on first articles because open pads are invisible from the surface.
Route input and output differential pairs at 100 ohm odd-mode impedance with length matching within 5 mil. Because the SY58052AUMG-TR input termination is internal and biased via the VT pin, do not add external parallel termination resistors on the input pair - doing so double-terminates and degrades eye amplitude. For AC-coupled links use 100 nF series capacitors placed near the receiver side. Keep via transitions to a minimum and use ground via fences beside the differential pairs to preserve return-path continuity.
Decouple each supply pin with a 0.1 uF ceramic capacitor placed within 2 mm of the pin, plus one bulk 4.7 uF capacitor per supply rail. The 2.375 V to 3.63 V operating window means a 3.3 V rail with 5% tolerance is acceptable, but verify rail droop at full data-rate switching. Estimated: a CML output pair switching 10.7 Gbps draws roughly 15-25 mA per side (verify against the datasheet current table), so a shared 3.3 V rail should budget at least 100 mA margin for this device including headroom.
A frequent mistake is treating the VT pin as a no-connect or tying it to ground. The VT pin sets the bias of the internal input termination network; its correct connection (per the datasheet application section) determines the input common-mode for the selected logic standard and coupling mode. Misconnecting VT shifts the input bias point, closes the input eye, and can prevent the synchronizer from locking. Always configure VT according to the datasheet table for your specific AC/DC-coupled interface standard.
