Micrel Rolls Out New Family of 4.25Gbps, 6.4Gbps Backplane & Cable Management Solutions

San Jose, Calif. - Micrel Inc., today launched a new family of backplane management solutions. The SY58620L and SY58621L are DC-to-4.25Gbps integrated transceivers (receiver & transmitter) and the SY58626L and SY58627L are a DC-to-6.4Gbps dedicated transmitter and receiver, respectively, with equalization and pre-emphasis. The ICs are aimed at Gigabit Ethernet, Infiniband, 1x and 4x Fiber Channel, and SONET/SDH serial Backplane or cable applications between 125Mbps-6.4Gbps. All products will be available for sampling in July 2005, with volume production in August 2005.

“Micrel’s new transceiver (SY58620/21L) backplane and cable management solutions provide a new level of integration for serial applications with the inclusion of a receiver, a transmitter, internal termination, and loopback capability in a small, 4mm x 4mm footprint,” said Thomas S. Wong, vice president high bandwidth products, Micrel. “Additionally, the SY58626L is the industry’s first transmitter to provide individual control of pre-emphasis magnitude and duration to optimize pre-emphasis levels for a given application.”

The SY58620/1L transceivers guarantee AC-performance up to 4.25Gbps over the full industrial temperature range (40°C to +85°C) and 3.3V 10% supply voltage range, while saving board space and component count by offering an integrated loopback mode for system diagnostics. The SY58620L transmitter features a programmable, differential CML compatible output with a programmable swing range between 100mV and 400mV with 50ohm internal source termination to minimize round trip reflections. The SY58621L transmitter output is differential LVPECL-compatible with a programmable swing range from 100mV to 800mV. The receiver for both devices accept any differential, AC-coupled input signal down to10mV (20mVp-p), and provides a Loss of Signal (LOS) alarm when the input signal is invalid. Both parts are offered in a 4mm x 4mm footprint, 24-pin MLF™ (QFN) package.

The SY58626L transmitter and SY58627L receiver feature a distinctive input stage that accepts AC- or DC-coupled input signals. Both devices offer guaranteed throughput from DC-to-6.4Gbps. The SY58626L transmitter includes a new programmable pre-emphasis feature — the pre-emphasis magnitude and duration are both programmed individually to optimize the emphasis level for many different transmission lines, data rates and backplane applications. The output is CML- compatible with 50ohm internal source termination and a programmable swing between 100mV and 1.5Vpk (3Vp-p). The SY58627L receiver accepts a degraded, differential input signal as low as 10mV and recovers the signal with an equalizer front-end. The equalizer is programmed in four discrete levels that correspond to typical FR4 transmission lengths between 9- and 36-inches. Both parts come in a 5mm x 5mm footprint, 32-pin MLF™ (QFN) package.
