VSC8479YYY - 11.3 Gbps 16-Bit Transceiver | Microchip
The Microchip Technology VSC8479YYY is a 1:16 and 16:1 high-speed serial transceiver operating continuously from 9.953 Gbps to 11.3 Gbps, with integrated clock and data recovery, clock multiplication, and a 244-FCBGA package measuring 17 mm by 17 mm. It serves OC-192, 10GbE, and 10GFC-oriented signal-chain designs that require parallel-to-serial and serial-to-parallel conversion in one device.
A high-speed transceiver is a semiconductor interface that converts wide parallel data into a high-speed serial stream and converts received serial data back into parallel form. The VSC8479 belongs to the broader transceiver and data-converter hierarchy while integrating timing-recovery functions needed to establish and recover a reliable high-speed data stream. Its 16-bit interface, continuous frequency coverage, and integrated CDR and CMU reduce the amount of external high-speed conversion circuitry required in communications equipment.
Key features include a 1:16 transmit fanout, a 16:1 receive aggregation, a 16-bit parallel data path, and a documented continuous operating span of 9.953 Gbps to 11.3 Gbps. The device is identified as a single Ethernet-class port transceiver by Mouser and as a telecom IC transceiver by DigiKey. Its single-chip, 17 mm by 17 mm implementation is specifically presented as a way to reduce board area and system cost in compact, price-sensitive modules.
The integrated clock and data recovery unit supports extraction or recovery of timing from the associated high-speed signal path, while the clock multiplier unit supplies the required derived clock functions. This integration can simplify synchronization architecture, but board implementation still requires careful high-speed layout, controlled impedance, short return paths, compliant clocking, power delivery, isolation, and signal-integrity verification. Exact power, voltage, pin, and environmental limits must be confirmed in the manufacturer datasheet before layout release.
Typical uses include 10GbE and 10GFC optical-module electronics, OC-192 transport interfaces, FEC equipment, telecommunications line cards, and compact high-speed network modules. The part is most appropriate where one device must support both serialization and deserialization functions at rates covered by its 9.953 Gbps-to-11.3 Gbps operating range. System designers should evaluate lane timing, reference-clock requirements, thermal performance, and protocol interoperability before production deployment.
The principal design consideration is that this is a very-high-speed mixed-signal device rather than a general-purpose serial interface. Its 244-FCBGA land pattern, multilayer routing, differential pairs, reference clocks, and decoupling network must be designed as one controlled signal-integrity system. Validate channel loss, jitter tolerance, crosstalk, return loss, and power-supply noise during prototype testing.
This product record combines verified manufacturer and distributor information with application guidance, sourcing context, and explicit data gaps. It does not infer missing electrical limits, pin assignments, lifecycle status, or unverified drop-in replacements; those details remain tied to authoritative Microchip documentation and approved cross-reference results.
