Micrel Announces Lowest Crosstalk 2x2 Crosspoint Switch Solutions

SAN JOSE, California, August 25/PRNewswire/ --


- SY58023U/SY58024U Chips Feature Low Jitter, Guaranteed AC Performance Over Temperature and Voltage

Micrel Inc. (Nasdaq: MCRL), an industry leader in Power, Connect and Protect IC solutions, today announced two new 2x2 ultra fast crosspoint switch ICs, the SY58023U and the SY58024U. The ICs are part of Micrel's high-speed, Precision Edge(TM) product line and are ideal for demanding networking applications that require low jitter and high crosstalk isolation between channels. The chips are currently shipping in volume with pricing starting at US$11.90 in 1K quantity.

Stubs become a major source of jitter as speeds increase to 2.5Gbps and beyond. Micrel's new SY58023U/ SY58024U, designed with internal termination, eliminate stubs resulting in unsurpassed jitter performance in a streamlined, reduced space design. The chips are optimized to provide two identical output copies with less than 20ps of skew and ultra-low jitter and can route data up to 10.7Gbps. The differential inputs include Micrel's patent-pending, 3-pin input internal-termination architecture allowing direct interfacing to any differential signals (AC-coupled or DC-coupled) using the termination resistors inside the IC. The CML outputs feature 400mV swing into 50 Ohm loads, and provide an extremely fast rise/fall times guaranteed to be less than 60ps.

Micrel has also created a patent-pending input isolation design reducing jitter contribution from channel-to-channel crosstalk to less than 0.7 psec (RMS). Internal termination and improved crosstalk isolation, combined with a guaranteed 10.7Gbps AC performance over voltage and temperature, make it possible for Micrel to offer the industry's most advanced family of ultra-low jitter solutions.

'Micrel's performance for these products is truly unique,' said Thomas S. Wong, vice president High Bandwidth, Micrel. 'Thanks to our innovative crosstalk isolation design work, we are the first chip maker to specify, and guarantee, crosstalk induced jitter in the sub-pico second range.'
