BCM8156 Interface Block Diagram
The BCM8156 is a fully integrated MSA-compatible multirate SONET/
SDH/10-GbE/Fibre-Channel/FEC transceiver operating at 9.953 Gbps,
10.3125 Gbps, 10.519 Gbps, 10.664 Gbps, 10.709 Gbps, 11.095 Gbps,
11.318 Gbps, or 11.352 Gbps. On-chip clock synthesis is performed by
the high-frequency, low-jitter PLL, allowing the use of a low-frequency
reference clock selectable to the line rate divided by either 16 or 64. The
10G TX clock phase is adjustable for clocked driver applications. An onchip phase detector and charge pump plus external VCXO implement a
cleanup PLL. The cleanup PLL can be used to attenuate jitter on the CDR
recovered clock for loop timing applications or to provide a low-jitter
reference clock from a noisy system clock. Any SONET timing mode
may be configured with the new BCM8156 timing architecture, making
the timing mode and cleanup functions user-selectable in the field rather
than during manufacturing, therefore, simplifying engineering and
manufacturing requirements.
New features added to the BCM8156 include:
• PRBS generator/checker for BIST
• 10G RX equalization for ISI compensation
• 10G TX preemphasis
• BSC interface (compatible with Philips I2C standard) or optional SPI
interface
The low-jitter LVDS interface guarantees compliance with the bit error
rate requirements of the Telcordia (formerly Bellcore), ANSI, and ITUT standards. The BCM8156 is offered in two different packages:
1. 15 mm x 15 mm, 301-pin BGA compatible with the BCM8152 (0.8mm ball pitch)
2. 15 mm x 15 mm, 196-pin BGA (1-mm ball pitch)
