Renesas offers a comprehensive selection of linear and limiting optical transimpedance amplifiers (TIA), and driver modulators for optical networks in data center applications and long-haul and metro applications. Our TIAs deliver flexible power-level control with programmable transimpedance and frequency range, all in a small footprint.
Low-power transimpedance amplifiers, with integrated post-amplifier (TIA+PA), provide high performance and data rates, as well as low power and emissions. These TIA+PA receiver arrays enable chip-to-chip, board-to-board, and system-to-system optical interconnects—removing the constraints of copper cabling and enabling higher data rates with significantly less EMI and power consumption.
Available in die form, Linear TIAs feature excellent gain, noise performance, and power dissipation. We also offer limiting TIAs in die and packaged form for DPSK and DQPSK receivers. Our TIA solutions address a wide variety of ROSA requirements—high input sensitivity, superior transimpedance gain, minimal noise/jitter, low power consumption, or high voltage output, or a combination of these.
