VSC8479YHQ-01 概要
A SerDes (Serializer/Deserializer) is a mixed-signal integrated circuit that converts between parallel and high-speed serial data streams while embedding clock recovery, equalization, and line-coding functions. As a class of physical-layer (PHY) interconnect ICs, SerDes devices sit between the MAC/ASIC framer and the optical module, forming the bridge between the digital chip domain (typically LVDS/PECL parallel buses) and the analog serial optical/electrical domain. The VSC8479 family belongs to the multi-rate 10G transceiver category, which spans oversampled and bit-serial architectures for telecom and datacom line cards.
Key features include integrated CDR with low-jitter performance, a reference-less or reference-clock CMU for synthesizing the line-side baud clock from a low-frequency system reference, programmable transmit pre-emphasis and receive adaptive equalization for backplane and optical reach extension, and an I2C/SPI management interface for system bring-up. The 195-FCBGA package uses controlled-collapse chip connection with flip-chip die attach, providing short electrical paths for multi-GHz signals and a thermal envelope suitable for forced-air-cooled line-card environments.
Architecture-wise, the device integrates four physical lanes (per SFI4.1 direction) with 16-bit datapaths, internal AC-coupling, and on-chip termination. The 17 mm x 17 mm footprint described in vendor collateral refers to the bare die-area footprint class typical of FCBGA-195 assemblies, enabling cost and board-area reduction for SFP+/XFP module and small-form-factor line-card designs.
Typical applications include 10G Ethernet SFP+ and XFP transceivers, OTN OTU2 line cards, SONET OC-192 short-reach modules, multi-rate muxponder/framer I/O, and 10G Fibre Channel host-bus adapters. Per the vendor product page, every device is tested at high speed to ensure production-grade performance.
Designers should evaluate AC-coupling capacitor selection, PCB material (low-loss FR-4 or Megtron), and matched-length routing for the four differential lanes to meet SFI4.1 jitter masks. The integrated CDR reduces BOM by eliminating an external clock-recovery block.
This page aggregates distributor stock, parametric drop-in alternatives, and engineering design notes that complement the Microchip datasheet and Mouser spec summary (msco-s-a0003388128-1).

主な用途
VSC8479YHQ-01 の用途: 7 件s: 10G Ethernet SFP+ Optical Module, OTN OTU2 Line Card / Transponder, SONET OC-192 Short-Reach Module, 10G Fibre Channel Host-Bus Adapter, Multi-Rate Muxponder / Framer I/O, 10G XFP Optical Transponder Module, Backplane 10G Line-Card Interface.
10G Ethernet SFP+ Optical Module
The VSC8479YHQ-01's continuous-rate 9.953-11.35 Gbps operation covers 10GBASE-R (10.3125 Gbps) with margin for rate-adjust, while the integrated CDR and CMU eliminate external clock-recovery ICs inside the SFP+ cage. The 195-FCBGA (12x12) flip-chip footprint enables dense PCB layout required for hot-pluggable optics, and the SFI4.1 16-bit interface connects directly to the module's MAC/ASIC framer. Versus a discrete CDR + SerDes implementation, the integrated path reduces BOM by 2-3 ICs and shortens the analog signal run for better jitter margin.
おすすめ
OTN OTU2 Line Card / Transponder
For OTN OTU2 at 10.709 Gbps with FEC, the VSC8479YHQ-01 supplies the line-side serializer toward the optical interface while the integrated CMU synthesizes the 10.709 Gbps baud from a low-frequency reference. Its SFI4.1 16-bit parallel datapath interfaces directly to OTN framer ASICs and FPGAs on the client side, allowing muxponder cards to aggregate multiple 10G clients. Per the Microchip product page, the device is tested at high speed to ensure production-grade OTN line-card performance.
おすすめ
SONET OC-192 Short-Reach Module
The VSC8479YHQ-01 supports OC-192c/STM-64 line rates including FEC-overhead variants around 10.664-10.709 Gbps, making it a strong fit for short-reach OC-192 modules and line cards. Its integrated CDR handles the SONET jitter transfer mask without external clock-recovery components, while transmit pre-emphasis and receive equalization compensate for FR-4 backplane loss in central-office chassis. The I2C/SPI management interface allows the host to monitor SONET BER and CDR lock in real time.
おすすめ
10G Fibre Channel Host-Bus Adapter
For 10G Fibre Channel (10.51875 Gbps) HBAs and storage switches, the VSC8479YHQ-01 acts as the line-side SerDes interfacing to SFP+ optics while the SFI4.1 16-bit bus connects to the FC controller ASIC. The integrated CDR maintains tight jitter performance required for FC link training, and the device's 9.953-11.35 Gbps range supports both standard FC and FEC-enhanced profiles. The 195-FCBGA package is compatible with HBA form-factor thermal envelopes.
おすすめ
Multi-Rate Muxponder / Framer I/O
Muxponder line cards aggregate multiple lower-rate clients (e.g., 4x GbE) onto a single 10G wavelength; the VSC8479YHQ-01 serves as the 10G line-side I/O with rate-agile operation that lets a single PCB support OTU2, OC-192, 10GE, or 10G FC without re-spin. The integrated CMU synthesizes the line baud from a single low-frequency system reference, simplifying board clock tree design. SFI4.1 parallel interface maps naturally to multi-channel framer ASICs used in muxponder designs.
おすすめ
10G XFP Optical Transponder Module
In XFP modules - the larger 10G pluggable form factor - the VSC8479YHQ-01 fits the XFP's available PCB area and provides the 9.953-11.35 Gbps rate agility required for tunable-XFP modules. Its integrated CDR/CMU eliminates the need for separate clock-recovery and multiplier ICs, freeing board area for the tunable laser driver and APD bias network. The -5 C to +90 C operating range matches XFP module inlet temperature specifications in central-office and controlled-environment deployments.
おすすめ
Backplane 10G Line-Card Interface
The VSC8479YHQ-01's transmit pre-emphasis and adaptive receive equalization compensate for backplane insertion loss on FR-4 or Megtron traces, allowing 10G signals to traverse 30-50 cm of backplane. The integrated CDR handles the accumulated jitter, and the SFI4.1 16-bit parallel bus simplifies ASIC-to-backplane connectivity on switch-fabric line cards. Programmable equalization settings can be tuned per channel via I2C during system bring-up.

設計ノート
Use low-loss PCB material (Megtron 6 or equivalent low-loss FR-4) for the four SFI4.1 differential lanes and the 10G serial-side TX/RX traces. Maintain 100 ohm differential impedance with matched-length routing (length matching within 150 mil across a lane). Place AC-coupling capacitors as close to the FCBGA ball pads as possible to minimize stub effect on multi-GHz signals.
The 195-FCBGA dissipates significant heat at full 10G operation. Provide a thermal via array under the die area connecting to internal ground planes and use forced-air cooling for chassis deployments. Junction temperature must remain within the rated 90 C commercial grade limit; derate ambient for altitude or sealed enclosures.
Program transmit pre-emphasis and receive adaptive equalization via the I2C/SPI interface during bring-up to compensate for backplane and connector losses. Reference clock jitter must be below the CDR's loop bandwidth requirement; use a low-noise crystal oscillator or jitter-cleaner upstream. Verify SFI4.1 eye mask compliance at the ASIC pins, not at the SerDes balls.
Do not assume pin-compatible across all VSC8479 suffix codes - firmware masks differ. Verify firmware revision matches the customer's provisioning script before production ramp. Ensure moisture-sensitive handling per JEDEC J-STD-033 for FCBGA packages (MSL rating should be confirmed with the manufacturer for the specific YHQ suffix).
