HMC6590

Overview

The HMC6590 is a high-speed, low-power limiting transimpedance amplifier (TIA) designed for optical receivers with data rates up to 43 Gbps. It features a 36 GHz bandwidth, 4 kOhm differential small-signal transimpedance gain, and an input-referred noise density of 20 pA/√Hz. The device operates on a single 3.3V ±5% supply, dissipating less than 300 mW. It provides an optical input dynamic range from -10 dBm to +5 dBm while maintaining a 10^-12 BER at 43 Gbps. Available in die form, it includes an on-chip VCC bypass capacitor.
