VSC8247
PRODUCT BRIEF
Quad Port 8.5 Gbps to 11.3 Gbps CDR with EDC
Vitesse’s new high-performance clock and data recovery (CDR) IC provides superior signal integrity, speed
flexibility, 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.
Highlights
• Broad application support
Operating at 8.5 Gbps to 11.3 Gbps, the VSC8247 is a versatile CDR and
• High-performance analog EDC
retimer for all 10G Ethernet and SONET applications. VSC8247 also
• High-density receiver
supports 8G Fibre Channel and 10G QDR Infiniband protocols and data
rates, and all legacy rates. The VSC8247’s flexibility makes it an excellent
candidate for upcoming 4×10G and 10×10G CFP modules and high-density
photonic integrated circuit (PIC) designs.
Applications
• Long-haul SMF platforms
• FEC-enabled systems
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 fiber systems, and modal dispersion in multimode
fiber systems. High-performance FFE-DFE EDC technology compensates
for fiber signal impairment and PCB-related signal degradation. Feedback
from an FEC device can be used for further optimization and enhanced
performance.
• 40G/100G CFP module designs:
4×10G, 10×10G, and 10×12G
Each channel includes an independent VScope™ input signal monitoring
integrated circuit and built-in error detector to facilitate product design, production, and deployment.
