The TGA4943-SL consists of three high performance wideband amplifiers assembled in a surface mount package combined with a minimum of off-chip components. A single TGA4943-SL placed between the MUX and Optical Modulator Vin = 0.5 Vpp, Vout = 8Vpp, 21.5 Gbps, PRBS 2 31 -1 provides OEMs with a modulator driver surface mount solution. The TGA4943-SL provides Metro and Long Haul designers with system critical features such as: low power dissipation, low rail ripple, 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 = 8Vpp). The TGA4943-SL finish is lead-free. RoHS compliant. Evaluation boards are available upon request.
