Product Description
Broadcom Multirate 40-Gb/s 16:1 Multiplexer with DPSK/Duobinary Precoder - BCM84148
Serializer/Deserializer (SerDes) Framer Interface Level 5 (SFI-5.1) multiplexer for use in 300-pin MSA 40 Gb/s modules.
The BCM84148 has an OIF-SFI-5.1-compliant 16-bit wide receive system data interface with a deskew channel operating from 2.488 Gb/s to 2.788 Gb/s that multiplexes and precodes the data to the serial transmitter (operating from 39.8 Gb/s to 44.6 Gb/s). There is an additional deskew lane for the SFI-5.1 interface. The multiplexer and precoders are fully integrated to accept SFI-5.1 data along with a deskew channel copying data sequentially from each data channel. The data can be precoded with a selectable DPSK or duobinary precoder. The SFI-5.1 timing clock is generated from the recovered clock. The extracted data can be fed to a PRBS decoder.
