BCM82381中文资料Dual 100GbE CAUI4-to-CAUI4 PHY/Octal 25G Retimer数据手册Broadcom规格书

描述 Description

The BCM82381 is a low-power, low-latency PHY integrating retimer and equalizer functions that support 100-Gigabit Ethernet (GbE), 40GbE and 10GbE applications.
 In 100G mode, the BCM82381 supports two full-duplex 100G ports (CAUI4-to-CAUI4) for SR4, LR4, and copper CR4 CFP2/CFP4/QSFP2 line-card applications. In 40G mode, the BCM82381 supports two full-duplex 40GbE ports (XLPPI-to-XLAUI) for SR4, LR4, and copper CR4 QSFP+ line-card applications. In 10G mode, the BCM82381 supports eight full-duplex 10GbE ports (SFI-to-XFI) for SR, LR, and copper CR SFP+ line-card applications.
 
On-chip clock synthesis is performed by a low-cost 156.25 MHz reference clock (for all IEEE Standard 10G/40G/100G rates) via high-frequency, low jitter phase-locked loops (PLLs). Individual clock recovery is performed on the device by synchronizing directly to the respective incoming data streams.
 
The BCM82381 was designed in 28 nm CMOS technology to provide a low-power, low-latency solution with integrated AC coupling capacitors for direct interfacing to Broadcom’s switch products. The BCM82381 is available in a 19mm x 19mm, 324-pin BGA, RoHS-compliant package.
