The 4953 consists of two high performance wideband amplifiers combined with off chip circuitry assembled in a surface mount package. A single 4953 placed between the MUX and Optical Modulator provides OEMs with a board level modulator driver surface mount solution. The 4953 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).
