Ottawa-based Zarlink Semiconductor Inc. today announced that its ZL 50408 Ethernet switch has been incorporated into a Texas Instruments Inc.’s carrier-class VoIP gateway reference design.

The design is based around TI’s digital signal processing (DSP)-based TNETV3010. Zarlink’s ZL50408 Fast Ethernet chip routes traffic between the DSP and an IP network.

The ZL50408 Ethernet switch line supports three standard interfaces on each port: IEEE 802.3 MII (media-independent interface), RMII (reduced media-independent interface), and GPSI (general purpose serial interface).

According to Zarlink, they help reduce overall costs and simplify design by allowing direct, seamless connections to DSPs and IP networks without requiring external conversion logic.

“As Ethernet becomes pervasive in the metro access environment, service providers and equipment manufacturers require solutions that utilize Ethernet to effectively process time-sensitive traffic,” said Paul Vu, product line marketing manager of packet switching at Zarlink.
