BCM84147

Multirate 40-Gb/s 1:16 DeMUX with CDR, VGA and Advanced Feature Set

Currently Viewing:

45G serial to SFI-5.1 demultiplexer (DeMux) for use in 300-pin 40G modules.
 
The BCM84147 has an OIF SFI-5.1 compliant 16-bit wide transmit system data interface with a deskew channel operating from 2.488 Gb/s to 2.788 Gb/s. The BCM84147 has two clock and data recovery (CDR) circuits that recover the clock and data from the received signals and then demultiplexes and transmits the data on the SFI-5.1 interface. There is an additional deskew lane for the SFI-5.1 interface. The CDR and demultiplexer are fully integrated. The data is recovered by the integrated CDR. The recovered data is interleaved to the SFI-5.1 interface along with a deskew channel copying data sequentially from each data channel. The SFI-5.1 timing clock is generated from the recovered clock. The extracted data can optionally be fed to a PRBS detector.
