Discovery Semiconductors, Inc. Introduces 10 Gb/s InGaAs APD + TIA + CDR Lab Buddy Instrument


Ewing, NJ - January 12, 2012

Discovery Semiconductors, a leading supplier and innovator of optical receivers, introduces 10 Gb/s InGaAs APD + TIA + CDR Lab Buddy instrument for SONET, Ethernet, PON, and Fiber Channel applications. In addition, Discovery is now offering both its 10GHz linear PIN + TIA and 10 Gb/s High-Sensitivity Limiting PIN + TIA with a CDR Lab Buddy option. The O/E section provides the receive and regenerate functions, and the CDR provides the clock and data recovery function from the input signal.

Discovery’s APD + CDR Lab Buddy includes a limiting amplifier with LOS power detector, and PLL data re-timer with a LOL indicator. The Lab Buddy supports multi-rate operation from 9.5 Gb/s thru 11.1 Gb/s. The CDR function has a 7mVp-p Input Sensitivity and 0.6UIp-p total high-frequency jitter tolerance. The clock and data outputs are compatible with BER test stations.

Furthermore, the APD + CDR Lab Buddy has a programmable bias voltage source and a built-in temperature controller for improved gain stabilization and increased reliability. The bias and temperature can be set either from the front panel or via a remote computer interface. The APD + CDR Lab Buddy monitors the bias, temperature, and average DC photocurrent of the APD in real-time.

Mr. Roy Howard, Applications Specialist at Discovery Semiconductors added, “The new APD + CDR Lab Buddy aims to maximize your test time by simplifying your measurement. This is accomplished through the combination of the O/E & CDR functions by providing both clock and data electrical outputs conveniently to your scope or BERT.”
