Optical Modulator Driver Designed for High-Speed Comms

Manufactured by TriQuint Semiconductor, the new MSA-compatible device comprises two high-performance wideband amplifiers combined with off-chip circuitry, all assembled into a surface-mount package measuring only 11.4 x 8.9 x 2.0mm.

The TGA4954-SL provides a number of essential features for designers of
metropolitan and long-haul systems, including data rates of 9.9 to
12.5Gbit/s, a wide drive range of 3 to 9V, low power dissipation of
typically just 1.1W, low rail ripple and low output jitter.

Other key performance specifications include 25ps edge rates, a low input
drive sensitivity of 250mV, input and output return losses of 9dB, and a
noise figure of 2.5dB at 3GHz.
