General Description
Pin Configuration
The TriQuint TGA4947-MOD is a 4-channel optical modulator driver amplifier designed to operate at frequencies that target the 100 Gb/s optical market using a 45.0 x 33.4 x 7.0 mm surface mount module. The TGA4947-MOD consists of four channels of high performance wideband amplifiers and integrated broadband bias tees, DC blocking caps, and necessary bypass caps assembled in a metal surface mount housing. A single TGA4947-MOD placed between the MUX and OIF pliant Optical Modulator provides OEMs with a modulator driver solution. The TGA4947-MOD provides Metro and Long Haul designers with system critical Features such as: low power dissipation, high signal to noise (SNR) ratio, high voltage drive capability (3 Vpp amplitude adjustable up to 9 Vpp), low output jitter, and low input drive sensitivity (0.4 Vpp
- 1 Vpp at Vout = 8 Vpp). The TGA4947-MOD finish is lead-free. RoHS pliant. Evaluation boards and bias boards are available upon request.
