It supports RZ, NRZ, and duo-binary modulation formats. On-chip clock synthesis is performed by a high-frequency, low-jitter PLL, allowing the use of a low-frequency reference clock selectable to the line rate divided by 16 or 64. The 10G TX clock phase adjusts for clocked driver applications. An on-chip phase detector and charge pump, plus external VCXO, implements a cleanup PLL. This can attenuate jitter on the CDRrecovered clock for loop timing applications, or provide a low-jitter reference from a noisy system clock. SONET timing modes can employ the new BCM8155 architecture, making timing mode and cleanup functions user-selectable in the field rather than during manufacturing. This simplifies engineering and manufacturing requirements. The low-jitter LVDS interface guarantees compliance with the bit error rate requirements of the Telcordia (formerly Bellcore), ANSI, and ITUT standards. New features added to the BCM8155 include: • Selectable RZ, NRZ and DB modulation • Rates from 8.5 Gbps to 11.352 Gbps • PRBS generator/checker for BIST • Adaptive decision threshold adjustment • Adjustable 10G TX clock phase • 10G RX equalization for ISI compensation • 10G TX preemphasis • Differential duo-binary precoder • BSC interface (compatible with Philips I2C standard) or optional SPI interface The BCM8155 is offered in two different packages: 1. 12 mm x 12 mm, 196-pin BGA (0.8 mm ball pitch) 2. 15 mm x 15 mm, 196-pin BGA (1 mm ball pitch) Broadcom®, the pulse logo, Connecting everything®, and the Connecting everything logo are among the trademarks of Broadcom Corporation and/or its affiliates in the United States, certain other countries and/or the EU.
