Applied Micro Circuits Corp.'s Columbia family of 10Gbps framer/mapper devices targets ATM and packet-over-SONET applications, including edge routers and multiservice switches.

Developed in a 0.13?m process, the devices span the OC-3 to OC-192 range and include the S19219 16x12 framer/mapper, S19207 4x48 framer/mapper, and S19218 framer/mapper.

The 16x12 device is equipped with 16 ports that can handle OC-12 or OC-3 streams as well as an SPI 4.2 interface. It also provides mux, demux, and clock-and-data recovery (CDR) functions at 155MHz and 622MHz.

The 4x48 framer/mapper can take in four OC-48 pipes to support 10Gbps operation, and provides mux, demux, and CDR functionality at 2.488GHz. It also supports channelization down to STS-12c/VT-4-4c, thus simplifying connectivity to add-drop multiplexers.

The S19218 IC is optimized for OC-192 SONET/SDH and 10GbE traffic streams. It comes with an SFI 4.2 interface, a 4x2.5GHz clockless interface and a protocol-agnostic interface. Also included is an 802.3ae-compliant media-access controller.

Each device is packaged in a 624-pin PBGA package. Samples are expected in Q1 of 2003.
