Microsemi’s new high-performance clock and data recovery (CDR) IC
provides superior signal integrity, speed fl exibility, programmable output,
and integrated diagnostics for optical applications.
The VSC8247 is a quad channel clock and data recovery (CDR) receiver
with on-chip adaptive electronic dispersion compensation (EDC),
programmable input equalization, and selectable pre-emphasis output.
Operating at 8.5 Gbps to 11.3 Gbps, the VSC8247 is a versatile CDR
and retimer for all 10G Ethernet and SONET applications. VSC8247
also supports 8G Fibre Channel and 10G QDR Infi niband protocols and
data rates, and all legacy rates. The VSC8247’s fl exibility makes it an
excellent candidate for upcoming 4×10G and 10×10G CFP modules
and high-density photonic integrated circuit (PIC) designs.
Integrated EDC compensates for signal degradations in both the
optical and electrical domains. For optical systems, this includes
chromatic dispersion in long-haul single mode fi ber systems, and modal
dispersion in multimode fi ber systems. High-performance FFE-DFE EDC
technology compensates for fi ber signal impairment and PCB-related
signal degradation. Feedback from an FEC device can be used for
further optimization and enhanced performance.
Each channel includes an independent VScope™ input signal
monitoring integrated circuit and built-in error detector to facilitate
product design, production, and deployment.
