VI Systems Intros Low Power 40 Gbit/s TIA For Optical Transceivers

A new generation of ultrahigh-speed transimpedance amplifier(TIA) chips for future high speed optical transceivers is available for testing. VI Systems offers these very low power TIA chips in addition to their line of low power ultrahigh-speed VCSEL and photodetector PIN diode components at 850nm and 980nm for data rates of up to 40 Gbit/s.

Berlin, Germany - VI Systems GmbH, a leader in ultra-high speed optical components for data communications, introduces the T40-150C integrated circuit for optical transceivers. This transimpedance amplifier (TIA) chip is designed for the use in high speed optical transceivers with a data rate of up to 40 Gbit/s. The T40-150C is specified for PIN photodetectors and is capable to amplify input currents of up to 2mA p-p with low duty cycle distortion. The chip provides an input sensitivity of -13 dBm while maintaining a BER of 10-12. The TIA operates off a single + 3.3V power supply and is in available as die. It features a low power consumption of only 145mW.

Target applications are short reach and very short reach optical receivers and transceiver modules used in optical communication networks as well in chip-to-chip optical interconnects in the computer industry. Future serial standards at data rates of more than 10 Gbit/s are currently developed within Common Electrical Standard (CEI-11Gbit/s) , SATA 11Gbit/s, Fiber Channel 17 Gbit/s and Ethernet IEEE 40/100 Gbit/s as well as in a number of custom specific application.

The T40-150C chip is available as engineering sample in die form. The dimensions are 800 µm x 600 µm.
