SY88149HL - 3.3V 1.25Gbps Burst-Mode Limiting Amplifier
The SY88149HL is a high-sensitivity, burst-mode capable limiting post amplifier designed for Optical Line Terminal (OLT) receiver applications.
The SY88149HL satisfies the strict timing restrictions of the GPON standards by providing ultra-fast Loss-of-Signal (LOS) or Signal-Detect (SD) output.

SY88149HL Features
* a JAM function which, when active, disables the LVPECL outputs. JAM is active LOW when SD is selected and active HIGH when LOS is selected. The LOS/SD output should be fed back to the JAM input to maintain output stability under an invalid signal condition. Typically, 3dB SD hysteresis is provided t
