Infineon Technologies AG has announced the availability of the Titan 768MD optical networking chip that can perform both interface conversion and serdes operations.

Packaged in a 680-pin BGA, the device is suitable for use in SONET and data communication applications, including in 40Gbps OC-768 line cards to perform SFI 4-to-SFI 5 interface conversion.

In addition, the Titan 768MD can perform inverse multiplexing of the OC-768c payload from a router. When used with a high-speed framer and pointer processor, such as the Infineon Titan 19244, the Titan 768MD provides a two-chip OC-768 solution for line cards operating at a 40Gbps throughput.

The chip can also function as a high-density serdes in router/switch line cards and backplanes to aggregate as many as 64 622Mbps channels into up to 16 2.5Gbps channels, or to convert the 2.5Gbps channels into 622Mbps outputs. Titan 768MD allows OEMs to continue using legacy systems in which core logic is implemented as FPGAs with 622Mbps interfaces.

Integrated into the Titan 768MD are robust clock and data recovery 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.

In addition, a microprocessor interface allows a CPU to access the registers for reset, setup, read, load, or to invoke built-in test functions.
