Product Details
The HMC7590 is a high-speed, high gain, low-power limiting transimpedance amplifier (TIA)
used in optical receivers with data rates up to 43 Gbps. It features low input referred noise, 36
GHz bandwidth, 4 kΩ differential small signal transimpedance and output cross point
adjustment. HMC7590 exhibits an optical input dynamic range between -10 dBm and +5 dBm
while maintaining 10e-12 BER at 43 Gbps operation.
The HMC7590 is available in die form, includes an on-chip VCC bypass capacitor. It requires
only supply decoupling capacitor as external component.
The HMC7590 requires a single 3.3V ±5 % supply and it typically dissipates less than 300 mW.
The device is characterized for operation from –5 °C to +85 °C case (IC back side) temperature.
Applications
• 40 GBase-FR4
• 40 GBps VSR / SFF
• Short, intermediate, and long-haul optical receivers
