Transceiver boosts 10Gbit over copper

Pulsar Electronics has a XAUI to CX4 retiming transceiver that exceeds the IEEE802.ak (10GBase-CX4) standard by extending copper reach to 25m, providing a 60% increase in performance.

The MY3124 manufactured by Mysticom addresses the growing demand for cost effective 10 Gigabit intersystem connections in data centre server/switch and stackable Gigabit switch type applications.

It provides an alternative to expensive optical component based solutions and reduces the overall link cost by over 75%.

The MY3124 features a dual 10 Gigabit Ethernet serial interface with programmable datarates from 1 to 3.1875Gbit/s.

Based on the IEEE802.ak (10GBase-CX4) draft, the MY3124 incorporates a rich set of adjustable link parameters that enable error free transmission over a wide range of system impairments.

The device can also be applied to FR4 copper backplane applications providing signalling distances in excess of 70in.

The MY3124 has eight independent serial channels ideal for high-density multigigabit applications and supports 1x, 2x and 10G Fibre Channel, Infiniband as well as Gigabit Ethernet protocols.

Each channel has optional forward error correction (FEC) that can dramatically reduce bit error rates (BER) to less than 10e-17 and/or extends signalling distance by more than 40 %Five adjustable link parameters are featured on the device including: transmit amplitude, pre- emphasis, and impedance; and receive equalisation and input impedance.

These reduce intersymbol interference, improve jitter tolerance and facilitate NEXT/FEXT impairment reduction.

A Real-time signal quality indicator (SQI) is also included for performance/power consumption optimisation.
