New M02025 and M02028 Transimpedance Amplifiers from Mindspeed

Developer of semiconductor products for wireless and wireline networks, Mindspeed Technologies, has introduced new, advanced 2.5 Gb/s M02025 and 1.25 Gb/s M02028 transimpedance amplifiers.

The 1.25 Gb/s M02028 and the 2.5 Gb/s M02025 transimpedance amplifiers enhance the dynamic range and optical sensitivity and includes new features to support numerous transmission distance needs. The high-sensitive amplifiers can identify signals in a noisy setting and is suitable for high-split-ratio PON networks. The M02025 amplifiers’ sensitivity, in Receiver Optical Sub Assembly applications, is better than -30dBm at 2.5 Gb/s and better than -28dBm at 3 Gbps when utilized with a PIN diode.

The M02025 transimpedance amplifier supports multiple data rates from 1.25 to 3 Gb/s, while the M02028 supports data rates from 100 Mb/s to 1.25 Gb/s. The amplifiers utilize the internal Receiver Optical Sub Assembly power supply decoupling caps and the photodiode filtering caps to reduce the costs of Receiver Optical Sub Assembly. The devices are designed with photodiode current outputs, which support both APD and PIN based photodiode monitoring with enhanced precision. They also contain on-die temperature sensors that are ideal for APD temperature monitoring applications.
