BCM8152 Block Diagram
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, in either
standard or Pb-free version.
