Vitesse Semiconductor Corp. (NASDAQ: VTSS) has introduced its SynchroPHY family of 1 Gigabit Ethernet (GbE), 10GbE, and 10GbE Optical Transport Network (OTN) PHYs. The chips leverage Vitesse’s VeriTime technology to support timing requirements in Ethernet, microwave, and OTN applications, including mobile backhaul.

The family includes:

  • VSC8572/VSC8574 Dual/Quad GbE PHYs
  • VSC8487-15/VSC8488-15 Single/Dual 10GbE PHYs
  • VSC8492/VSC8494 Dual/Quad Universal (10GbE or OTN) or 10GbE-only PHYs

The VeriTime technology offers the most accurate implementation of the IEEE1588v2 timing protocol in the industry, Vitesse asserts. The company has reported better than 3-ns per hop accuracy over a nine-hop IEEE1588v2 Transparent Clock (TC) network. Such performance makes VeriTime-enabled devices the only ones to fulfill TD-LTE and LTE-Advanced requirements in real-world tests, Vitesse claims.

In addition to new designs, Vitesse is targeting system upgrades, in which designers would improve the timing accuracy of their systems by replacing existing PHYs with SynchroPHY devices.

“Our SynchroPHY family enables sub-10-ns accurate timing through a simple upgrade of PHYs in existing routers and switches,” said Richard Interrante, product marketing director at Vitesse. “With Vitesse’s unique architectural approach, VeriTime-enabled solutions achieve the in-line speed and scalability crucial to the functionality of 4G service provider networks.”
