Device Overview

Summary

The 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. The SY88149HAL generates a high-gain LVTTL LOS or SD output. A programmable LOS/SD level set pin (LOS/SD LVL) sets the sensitivity of the input amplitude detection. For increased flexibility, this device also includes an option to select between LOS or SD output by using the LOS/SD SEL pin . The LOS/SD output can be fed back to the JAM input to maintain data output stability under an invalid input signal conditions. Typically, 3dB LOS/SD hysteresis is provided to prevent chattering. The SY88149HAL operates from a single +3.3V power supply, over temperatures ranging from -40°C to +85°C. With its wide bandwidth and high gain, signals up to 1.25Gbps and as small as 5mVPP can be amplified to LVPECL levels.
