General Description
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.
Key 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 to prevent chattering. The SY88149HL operates from a single +3.3V power supply over temperatures ranging from.
- 40oC to +85oC. With its wide bandwidth and high gain, signals up to 1.25Gbps and a.
