    Key Features

    • Metro MSA compatible
    • Wide drive range (3 to 10 V)
    • Single-ended input / output
    • Low power dissipation (1.1 W at Vo = 6V)
    • Very low rail ripple
    • 25 ps edge rates (20/80)
    • Small form factor: 11.4 x 8.9 x 2 mm (0.450 x 0.350 x 0.080 in)

    Qorvo's TGA4953-SL is part of a series of surface mount modulator drivers suitable for a variety of driver applications and is compatible with Metro MSA standards.

    The TGA4953-SL consists of two high performance wideband amplifiers combined with off chip circuitry assembled in a surface mount package. A single TGA4953-SL placed between the MUX and Optical Modulator provides OEMs with a board level modulator driver surface mount solution.

    The TGA4953-SL provides Metro and Long Haul designers with system critical features such as: low power dissipation (1.1 W at Vo = 6 V), very low rail ripple, high voltage drive capability at 5V bias (6 V amplitude adjustable to 3 V), low output jitter (1 ps rms typical) and low input drive sensitivity (250 mV at Vo = 6V).

    The TGA4953-SL requires external DC blocks, a low frequency choke and control circuitry. The part is RoHS compliant. Evaluation boards are available upon request.
