Product Description
Broadcom Multirate 40-Gb/s 1:4 Demux with CDR, VGA and Advanced Feature Set - BCM84145
45G serial-to-SFI-5.2/XLAUI/OTL3.4/STL256.4 demultiplexer (demux) for use in 300-pin 40G modules.
The BCM84145 has an Optical Internetworking Forum (OIF) SFI-5.2/XLAUI/OTL3.4/STL256.4-compliant four-bit wide transmit system data interface with a deskew channel operating from 2.488 Gb/s to 2.788 Gb/s. The BCM84145 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-5.2/XLAUI/OTL3.4/STL256.4 interface. There is an additional deskew lane for the SFI-5.2/XLAUI/OTL3.4/STL256.4 interface. The CDR and demultiplexer are fully integrated. The data is recovered by the integrated CDR. The recovered data is interleaved to the SFI-5.2/XLAUI/OTL3.4/STL256.4 interface along with a deskew channel copying data sequentially from each data channel. The SFI-5.2/XLAUI/OTL3.4/STL256.4 timing clock is generated from the recovered clock. The extracted data can optionally be fed to a PRBS detector.
