BCM82251数据手册Broadcom中文资料规格书

描述 Description

The BCM82251 is a low-power, low-latency PHY integrating retimer and equalizer functions that support 100GbE and 40GbE applications.
 In 100GbE mode, the BCM82251 converts 4 × 25GE traffic into 2 × 50GE PAM4 and is capable of driving Direct Attached Cable and SR/LR optics. In 40GbE mode, the BCM82251 converts 2 × 20GE traffic into 1 × 40GbE PAM4, and is capable of driving Direct Attached Cable and SR/LR optics. BCM82251 supports single and dual 40GbE operation. On-chip clock synthesis is performed by a low cost 156.25 MHz reference clock (for all IEEE standard 100GbE/40GbE rates) via high frequency, low-jitter phase-locked loops (PLLs).
 
The BCM82251 is available in 8mm × 8 mm, 0.65 mm pitch, 144-pin BGA, RoHS-compliant package.
