Product Overview

The SY88149NDLMG is a high-sensitivity burst-mode capable limiting Post Amplifier designed for Optical Line Terminal (OLT) receiver applications. The amplifier 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. For increased flexibility, this device also includes an option to select between LOS or SD output. The device can be connected to burst-mode capable trans impedance amplifiers (TIAs) using AC or DC coupling. The SY88149NDL features a selectable proprietary noise discriminator that aids by filtering out input signals that do not qualify as a 1.25Gbps GPON preamble signal in the initial startup phase. This feature minimizes false SD asserts that can be triggered by random noise.
  • High-sensitivity LOS/SD signal detect
  • Low-noise LVPECL data outputs
  • Squelching function to maintain output stability
  • Programmable LOS/SD level set (LOS/SDLVL)
  • 5mVp-p Input sensitivity
  • 1.25Gbps Operation
