Infineon Technologies AG (Germany) announced its new 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 a 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.
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. 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.
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.
