Infineon Technologies AG has rolled out the Titan 768MD interface converter IC that converts OC-192 data rates into OC-768 data rates, while preserving legacy system investments.

The Titan 768MD is 16:64 mux/demux IC that can convert 64-channel, 622Mbps, OC-192 SFI-4-compliant data into 16-channel 2.5Gbps OC-768/768c SFI-5-compliant data. It can also perform narrow-band SFI-5-to-SFI-4 conversion, interfacing with up to four OC-192 framers. This provides a data throughput of 40Gbps in both directions across a network while using 10Gbps framers.

In addition, the IC can perform inverse multiplexing of the OC-768c payload from a router, and can also serve as a standard 1:4 DEMUX of sixteen independent 2.5Gbps channels.

"The Titan 768MD was developed to address customer demand for a solution that would let them leverage existing 10Gbps components with SFI-4 interfaces while deploying 40Gbps systems with SFI-5 interfaces," said Christian Scherp, Vice President of Marketing at Infineon Technologies.

The 680-pin BGA device's line side complies with the SFI-5 specification, supporting 16 channels operating at between 2.5Gbps and 3.125Gbps. Its system-side interface complies with the SFI-4 specification, supporting 64 622MHz channels.

The chip demultiplexes the 16 high-speed channels into 64 lower speed channels, and multiplexes the 64 lower speed channels into 16 high-speed channels, providing an aggregate 40Gbps data throughput in both directions.

A microprocessor interface allows a CPU to access the registers of the Titan 768MD for reset, setup, read, load, or to invoke built-in test functions. The chip also features CDR mechanisms, skew compensation functions, and a clock synthesis mechanism.

Diagnostic features include Pseudo Random Binary Sequence generation and checking, digital loopback capabilities and support for IEEE 1149.1 JTAG testing.

The Titan 768MD can be used with a high-speed framer and pointer processor, such as Infineon's Titan 19244, to provide a two-chip OC-768/768c solution that addresses the needs of high-density line card applications for the emerging 40Gbps market.
