1/ These ratings represent the maximum operable values for this device
2/ Combinations of supply voltage, supply current, input power, and output power shall not exceed PD at a package base temperature of 80°C
3/ When operated at this bias condition with a baseplate temperature of 80°C, the MTTF is reduced
4/ Junction operating temperature will directly affect the device median time to failure (MTTF). For maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels.
5/ Assure V_CTRL1 never exceeds V_D1, and V_CTRL2 never exceeds V_D2T during bias up and down sequences.

Description

The TriQuint 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 (1.1W at Vo = 6V), very low rail ripple, high voltage drive capability at 5V bias (6 V amplitude adjustable to 3 V), low output jitter (1ps rms typical), and low input drive sensitivity (250mV at Vo = 6V).

The TGA4953-SL requires external DC blocks, a low frequency choke, and control circuitry.

The TGA4953-SL is available on an evaluation board.

RoHS compliant version available.
