MULTIRATE 10-GBPS CDR/DEMULTIPLEXER WITH
ELECTRONIC DISPERSION COMPENSATION
SUMMARY OF BENEFITS
FEATURES
• Fully integrated CDR and demultiplexer with AGC and
electronic dispersion compensator
• Extends the reach of single-channel and DWDM links
• Improves optical link budget
• Compensates 3000-ps/nm chromatic dispersion
• Compensates 50 ps of digital group delay caused by PMD
• Reduces need for expensive optics and passive dispersion
compensation components

BCM8105 Block Diagram
The BCM8105 is a fully integrated, MSA-compliant, multirate SONET/
SDH/10GE receiver supporting OC-192, 10 GbE, and FEC (forward
error correction) datarates. The product integrates a high-performance
clock and data recovery (CDR), 1:16 demultiplexer, electronic
dispersion compensator (EDC), loss of signal (LOS) detection circuitry,
and an advanced feature set.
The BCM8105 provides high jitter tolerance and low jitter generation to
comply with Optical Internetworking Forum (OIF), IEEE 802.3™ae,
Telcordia®, ANSI, and ITU-T standards.
The BCM8105 reference clock input frequency is user-selectable to the
line rate divided by either 16 or 64. The reference clock output and the
LVDS receive parallel bus output can be squelched under user control.
The BCM8105 can be powered with a single 1.8V supply or a dual 1.8/
3.3V supply without any special power supply sequencing requirements.
The BCM8105 comes in a 15 x 15-mm, 150-pin BGA package.
