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 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 is lead-free and RoHS compliant. Evaluation boards are available upon request. Datasheet subject to change without notice.

For maximum life, it is recommended that channel temperatures be maintained at the lowest possible levels. jc is modeled based upon hottest stage (stage 3) because there is negligible thermal coupling between stages. It is the thermal resistance of the part calculated from the junction to the bottom of the TGA4943-SL package. To calculate the temperature rise, calculate the dissipated power in the third stage (Pdiss = Idq3*Vd3) and multiply by jc. For example: Tbase = 85 Idq3 = 190 mA, Vd3 = 7V. Pdiss_stage3 = 1.33 W.
