NEC Electronics Corp. has announced a SerDes macro that meets the specifications of Reference Point 3 (RP3) of the Open Base Station Architecture Initiative (OBSAI).

The high-speed interface macro has been designed for the company's CB-130 ASIC technology. It includes multiple transmit units with a parallel-to-serial (P/S) converter, multiple receive units consisting of clock and data recovery (CDR) drivers, a serial-to-parallel converter (S/P) and a receiver. A common part integrates the PLL, bias generator and test logic, and controls up to 16 channels simultaneously. The 8-bit/10-bit coders and decoders are available as macros.

OBSAI is a group of nearly 70 manufacturers of wireless infrastructure equipment, related modules and components working to standardize the interfaces between different base station modules. The RP3 specification defines the interface between the baseband processing and radio components of a wireless base station. Data rates of 768Mbps and 1.536Gbps have been defined using XAUI-type Common Mode Logic (CML) transce
