SY88403BL 3.3V 4.25Gbps CML Low-Power Limiting Post Amplifier with TTL LOS General Description The SY88403BL is a low-power limiting post amplifier optimized for copper 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 SY88403BL quantizes these signals and outputs typically 800mVPP voltage-limited waveforms. The SY88403BL operates from a single +3.3V ±10% power supply, over an industrial temperature range of –40°C to +85°C. With its wide bandwidth and high gain, signals with data rates up to 4.25Gbps and as small as 5mVPP can be amplified to drive devices with CML inputs or AC-coupled PECL inputs.
