Highlights

• Standards supported include

• Support for SFP+ line modules and 10GBASE-

KR backplanes

• Internal cross-connect available

Applications

• Two-port serial-to-serial signal conditioning with

failover protection

• 10GBASE-KR-compliant backplane

transceivers

• Networks requiring high-accuracy time

stamping and synchronization

encryption. It also supports dual-sided 10GBASE-KR functionality including

auto-negotiation and training in a small form factor, low-power FCBGA

ideal for a wide array of board-level signal integrity designs and system-

level IEEE standard compliant (intelligent) Ethernet connectivity.

VeriTime™ is Microsemi's patent-pending timing technology that delivers

the industry’s most accurate IEEE 1588v2 timing implementation. It is the

only IEEE 1588v2 solution to be validated by major OEMs in real-world

tests and adopted as the preferred low-cost upgrade for meeting emerging

requirements in 4G/LTE-Advanced (LTE-A).

Intellisec™ is Microsemi's patent-pending fl ow-based extension of the

Target applications for the VSC8254 device include Ethernet switching,

IP edge router connectivity, rack mount connectivity through backplane,

fi ber and copper cable connectivity, and standalone server access (LAN on

motherboard designs or separate network adapters).

The VSC8254 device delivers excellent jitter attenuation with low power. It

is well-suited for SFP+ modules and direct attach copper cabling as well as

challenging backplane interface applications.

Built-in Self-Test and SyncE

instrumentation including built-in self-test (BIST) functions,

line-side and client-side circuit loopbacks, pattern generation,

and error detection. Its highly fl exible clocking options support

LAN and WAN operation using a single 156.25 MHz reference

clock rate. Support for Synchronous Ethernet (SyncE) is also

included.

Range of Support
