Digi-Key – Burst-mode limiting amplifier with ultra-fast signal assert timing (SY88149HALMG)

Mar 26 2012 - Semiconductors [More Semiconductors Articles]

Now available from Digi-Key, Micrel’s SY88149HAL is a high-sensitivity, burst-mode capable, limiting-post amplifier designed for FTTH PON optical line terminal (OLT) receiver applications.

The SY88149HAL satisfies the strict timing restrictions of the GPON standards by providing ultra-fast loss-of-signal (LOS) or signal-detect (SD) output. Auto reset and manual reset options are provided to control LOS/SD output timing. The device can be connected to burst-mode capable transimpedance amplifiers (TIAs) using AC or DC coupling, says the company.
