Micrel Inc. expanded its family of limiting post amplifiers with the introduction of the SY88903ALKG, SY88149CL, SY88313BLNG and SY88343BL devices, a series of 1.25Gbps to 3.2Gbps post amplifiers featuring 3.3V power supply, higher gain and higher sensitivity for either signal or loss of signal indicators.

The new chips are the latest solutions to be rolled out as part of the company's next-generation family of post amplifiers. These solutions were first launched in early 2005 and are designed to work for Fast Ethernet, OC3 to OC48 and parallel 10GE data rates.

"Micrel's newest post amplifiers are optimized for detecting wide variations in input levels and for sensing the low input signal levels typically encountered in optical network and PON applications," said Thomas Wong, VP of high bandwidth products at Micrel.

The SY88149CL, SY88315BL and the SY88343BL all feature high sensitivity SD or LOS path, and the ability to either detect signal or to detect loss of signal, which is a crucial feature for reducing system cost by allowing the use of lower gain TIAs.

The new amps are offered in the MSOP packaging, with backward-compatibility to Micrel's existing family of post amplifiers, with most also available in the tiny 10-pin MLF packaging. The SY88903ALKG, SY88149CL, SY88313BLNG and SY88343BL are already available for volume orders, with pricing starting at $1.95 for 10,000-unit quantities.
