Microchip | SY88149NDLMG-TR

The SY88149NDLMG TR is a 1.25 Gbps burst mode limiting post amplifier designed for optical line terminal receiver application. Available in surface mount QFN-16 package.

This device features a selectable proprietary Noise Discriminator that aids by filtering out input signals that do not qualify as a 1.25 Gbps GPON preamble signal in the initial startup phase. This feature minimizes false SD Asserts that can be triggered by random noise.

Features:

• 5 ns SD Assert (LOS Deassert) time
• Option to AUTO RESET or manual RESET LOS/SD output
• Selectable LOS/SD output option
• High-sensitivity LOS/SD signal detect
• Low-noise LVPECL data outputs
• Squelching function to maintain output stability
• Programmable LOS/SD level set (LOS/SDLVL)
• 5mVPP input sensitivity
• 1.25 Gbps operation
• Single 3.3 V power supply
• Available in a 16-pin (3 mm x 3 mm) QFN package

Applications:

• GE-PON/GPON
• Gigabit Ethernet
• Fibre Channel
• OC-3/12/24 SONET/SDH
• High-gain line driver and line receiver
• Low-gain TIA interface
