Zarlink Semiconductor today expanded its DirectConnect line of embedded Ethernet switches with a new high-capacity aggregation and switch device that it says simplifies the design of high-density media processing, data plane and control plane cards used in wired, wireless and cable networks.

The ZL33020 embedded Ethernet switch is a 24 FE (Fast Ethernet) + 4 GE (Gigabit Ethernet) port device with 3.75 Mbits (480 Kbytes) of embedded memory for control databases and frame data buffer.

The device supports multiple interface options, including SMII, RMII, GMII, TBI and MII, enabling designers to match a range of Ethernet interfaces available in complementary Ethernet devices.

“Ethernet has proven to be an efficient interface for connectivity between DSPs (digital signal processors), micro-controllers and NPUs (network processor units) in applications where heavy data traffic volume must be quickly processed andmanaged, including modem pools in wireless base stations, VoIP gateways, cable head-end modulators for IP video, high-end traffic management and controlplane cards,” the company said in a release.
