TGA4959-SL

TGA4959-SL 32Gb/s Differential Modulator Driver Applications 40 Gb/s Optical Market: DQPSK and DP-BPSK Product Features 40 Gb/s Performance Differential Input and Output Adjustable Output Amplitude, 6 Vpp – 9 Vpp Low Additive RMS Jitter, 580 fsec High Output Drive, 9 Vpp differential output with 1 Vpp differential input Gain, 24 dB at 16 GHz Low DC Power Dissipation, 2.2 W for Vout = 8Vpp at Vd=5 V Rise and Fall Times 13 psec Package Size: 10 x 7 x 2 mm Typical Electrical Eye, 32 Gbps Vout = 8Vpp, Vin = 0.5 Vpp per side, Vd = 5V, Id = 428 mA General Description The TriQuint TGA4959-SL is a differential input and output optical modulator driver designed to operate at frequencies that target the 40 Gb/s optical market. The TGA4959-SL consists of a wideband amplifier assembled in a surface mount package combined with a minimum of external components. A single TGA4959-SL placed between the MUX and Optical Modulator provides OEMs with a differential modulator driver surface mount solution. The TGA4959-SL provides Metro and Long Haul designers with system critical features such as: low power dissipation, low rail ripple, high voltage drive capability (6 Vpp amplitude adjustable up to 9 Vpp), and very low output jitter. Several of the bias pins on the TGA4959-SL are internally set to simplify the users PCB design. Alternatively, these same pins can be adjusted by the user, if desired. Duplicate pins are available to enable biasing from either side of the packa...
