SY84403BL Limiting Post Amplifier

Ultra Small 3.3V 4.25Gbps CML Low-Power Limiting Post Amplifier with TTL LOS - Available at Digi-Key

Click to Enlarge - SY84403BL Diagram Micrel, Inc.'s SY84403BL is the industry’s smallest limiting post amplifier ideal for compact copper and fiber optic module applications. The device connects to typical transimpedance amplifiers (TIAs). The linear signal output from TIAs can contain significant amounts of noise and may vary in amplitude over time. The SY84403BL quantizes these signals and outputs typically 800mVPP voltage-limited waveforms.     SY84403BL Datasheet
