Micrel Launches New Post Amplifier Featuring Improved Sensitivity for Datacom and Telecom Digital Applications

SAN JOSE, Calif., Sept. 26 /PRNewswire-FirstCall/ -- Micrel, Inc. (NASDAQ: MCRL), an industry leader in analog, high-bandwidth communications and Ethernet IC solutions, today added to its family of limiting Post Amplifiers by introducing the SY88903ALKG, a 1.25 Gbps Limiting post Amplifier featuring 3.3V operation with better than 5mV sensitivity. The IC is the latest part in Micrel's next-generation family of Post Amplifiers, first launched in early 2005, and designed to work at Gigabit and fiber channel data rates. The new IC is offered in a small form factor package and is ideally suited for optical modules and passive Optical Network (PON) systems. The SY88903ALKG is currently available in volume with pricing starting at $1.95 for 10K quantities.

"Some of the fastest growing communications systems and markets currently are found in the Fiber to the Home arena," said Thomas S. Wong, vice president high bandwidth products for Micrel. "Micrel's newest Post Amplifier addresses a strong need in this area because it has been optimized to address both the low input signals levels encountered in optical network applications and the wide variations in input levels that are typically found in many PON market applications."

The SY88903ALKG features high sensitivity loss of signal (LOS) circuitry which can reduce system cost by allowing the use of lower gain TIAs. It also offers fast LOS switching times, PECL data outputs with a TTL compatible LOS output -- ideal for applications where the LOS function is in the critical timing path. The IC's LOS switching thresholds has 3db (typical) electrical hysteresis between the LOS Assert and Deassert levels to eliminate chattering. It is backward compatible with Micrel's existing family of Post Amplifiers with minimal changes required. The part is offered in a small 3mm x 3mm footprint, 10-pin MSOP packaging.
