HMC7590-SX

Overview

The HMC7590-SX is a high-speed, low-power limiting transimpedance amplifier designed for optical receivers supporting data rates up to 43 Gbps. It features a 36 GHz bandwidth and a 4 kΩ differential small-signal transimpedance gain. The device provides an optical input dynamic range from -10 dBm to +5 dBm while maintaining a bit error rate of 10e-12. It operates on a single 3.3V ±5% supply with power dissipation under 300 mW. The component is characterized for case temperatures between -5 °C and +85 °C.

Feature Summary

• Features internal DC feedback with external adjustment options for output cross point control
• Includes an on-chip VCC bypass capacitor requiring only external supply decoupling
• Provides low input referred noise suitable for high-speed optical detection

Applications

• 40 GBase-FR4 systems
• 40 GBps VSR / SFF applications
• Short, intermediate, and long-haul optical receivers

Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Confirm that the SX designation corresponds to the correct tray packing quantity and die specifications. Ensure compatibility with the required 3.3V supply voltage and thermal management requirements for the specified operating temperature range.

Selection Notes

Select this component for designs requiring high bandwidth and low power consumption in optical receiver circuits. Consider the availability of external adjustment pins for optimizing the output cross point and bandwidth. Evaluate the thermal performance within the -5 °C to +85 °C case temperature range to ensure reliable operation under intended load conditions.
