The HMC6590 is a high-speed, high gain, low-power limiting transimpedance amplifier (TIA) used in optical receivers with data rates up to 43Gbps. It features low input referred noise, 39 GHz bandwidth, 4kΩ differential small signal transimpedance and output cross point adjustment. HMC6590 exhibits an optical input dynamic range between -10dBm and +5dBm while maintaining 10e-12 BER at 43Gbps operation.The HMC6590 is available in die form, includes an on-chip VCC bypass capacitor. It requires only supply decoupling capacitor as external component.The HMC6590 requires a single 3.3V ±5% supply and it typically dissipates less than 300mW. The device is characterized for operation from –5°C to +85°C case (IC back side) temperature.Applications40 GbE-F440 GBps VSR/SFFShort, intermediate, and long-haul optical receivers
