PRBS GENERATION AND ERROR-DETECTION ABOVE 10 GB S USING A MONOLITHIC SI BIPOLAR IC/

This paper describes the application of a monolithic Si bipolar IC to serve as a single-chip measurement instrument for pseudo-random binary sequence (PRBS) generation, bit error detection, de-scrambling, and t rigger derivation up to 12.5 Gb/s. The package interconnect problem of high I/O count multi-Gb/s IC's is addressed. The paper presents a pac kaging solution with improved ground contact and odd-mode controlled i mpedance differential microstrip transmission lines. A method for phas e synchronization of multiple PRBS generators is proposed and its feas ibility is demonstrated by measurement results.
