iT5060 12.5 Gb/s, 8 Vpp Modulator Driver
(for use with bias-tee)
Description
The iT5060 is a low-cost, plastic-packaged (QFP-N) broadband GaAs traveling-wave MMIC amplifier with high output voltage. In optical communication systems, it is well suited as a driver for EO/LiNo3 modulators by providing from 3 to 8 Vpp output voltage for NRZ signals up to 12.5 Gb/s. In low-voltage mode, the iT5060 can be used as a pre-driver for a 1.5 to 3 Vpp output voltage. The amplifier can also be used as an optical receiver amplifier gain stage for photodiodes or as a limiting amplifier after the transimpedance amplifier. It can operate from DC to 12.5 GHz with 14 dB linear gain, a +21 dBm P1dB compression point, and +23 dBm Psat.
