The Cortina Systems® CS4315 Electronic Dispersion Compensation Device (CS4315 EDC) is highly integrated with four 10 Gbps clock and data recovery (CDR) circuits. The two receive channels have the optional integrated Electronic Dispersion Compensation (EDC) capability. This functionality supports 2 SFP+ modules that can be either limited or linear. Enabling the EDC capability allows the device to operate with linear SFP+ optical modules to extend the operating range of 62.5 μm and 50 μm multimode fiber to 220 meters and beyond, and greater than 7 meters of Direct Attach Copper cable.
10G SFP+: In an SFP+ application, a single CS4315 EDC performs transmit and receive functionality required to support two SFP+ modules. The device supports all SFP+ port types including: 10GBase-SR, 10GBase-LR, 10GBase-LRM, and Direct Attach Copper. The high quality transmitter of the device enables longer board traces between the MAC and the PHY, which is an essential requirement for new high density designs.
Enterprise and Telecom backplanes: The CS4315 EDC 10Gbase-KR compliant 3 tap transmit pre-emphasis and receive equalizer enables 10G transmission over 1m of FR4 in the presence of connectors. In addition, the wide operating frequency range of the device makes it an ideal choice for backplane applications in the 9.95 and 11.3 Gbps range, and 8.5 G fibre channel applications.
Single mode fiber links: The CS4315 EDC can be used in both metro and long haul DWDM systems to compensate for chromatic dispersion and other distortions caused by the transmission medium. The device also includes threshold adjust capability, which is required to achieve optimal performance in a single mode application.- Designed to meet the requirements for systems and modules designed to SFF-8431 for both linear and limited
