The BCM8152 is a fully integrated MSA-compatible multi-rate
SONET/SDH/10GE/FEC transceiver operating at the OC-192/STM-64
(9.953 Gbps), 10GE (10.3125 Gbps), 10GFC (10.315 Gbps), or one of
three FEC (Forward Error Correction) (10.664/10.709, 11.096, or 11.31
Gbps) data rates with serializer, deserializer, integrated clock
multiplication unit (CMU), 10G clock, bus skew, limiting amplifier, data
recovery circuit (CDR), and enhanced feature set. On-chip clock
synthesis is performed by the high-frequency, low-jitter phase-locked
loop (PLL) on the BCM8152 transceiver chip allowing the use of a low-
frequency reference clock selectable to the line rate divided by either 16
or 64.
Clock recovery is performed on the device by synchronizing its on-chip
voltage-controlled oscillator (VCO) directly to the incoming data stream.
An on-chip phase detector and charge pump plus external VCXO
implements a cleanup PLL. The cleanup PLL can be used to clean up the
CDR recovered clock for loop timing applications or to clean up a noisy
system clock.
The low-jitter LVDS interface guarantees compliance with the bit error
rate requirements of the Telcordia, ANSI, ITU-T, and IEEE 802.3ae
standards.
The BCM8152 is packaged in a 15 x 15 mm, 301-pin BGA.
