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 lowfrequency 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.
