CMOS retimer with EDC for multimode fibre LAN

Phyworks has announced a fully 10GBASE-LRM compliant serial retiming receiver with Electronic Dispersion Compensation (EDC). Manufactured on a CMOS process, this second-generation EDC chip offers a powerful equaliser. The PHY2060 enables upgrade of X2 and XFP optical modules and SFP+ based line cards to true 10Gbps LRM operation.Combining clock data recovery (CDR) and a fully automatic EDC circuit, the integrated PHY2060 simplifies optical module design. The chip’s internal algorithms remove the need for complex microcontroller support. The IC is in a miniature 36-pin, 5mm x 5mm flip-chip BGA packaging. To simplify product evaluation and qualification the PHY2060 also includes a PRBS generator and a BER detector, enabling end-to-end link testing. On boot-up the device automatically selects between the chip’s 2-wire or serial peripheral interfaces. Phyworks’ proprietary, fully LRM compliant EDC technology is dedicated for overcoming modal dispersion in multimode fibre LAN infrastructure and achieving reliable 300m link lengths. PHY2060 samples and an evaluation board are available now. The chip is priced at $25 USD in volume.
