TGA4943-SL

TGA4943-SL 28 Gb/s 8Vpp Optical Modulator Driver Key Features 28 Gb/s Performance Single Ended Input and Output Adjustable Output Amplitude, 3 Vpp – 9 Vpp Low Additive RMS Jitter, 400 fsec High Output Drive, 8Vpp with 0.4 Vpp Input Gain, 32 dB at 20 GHz Low DC Power Dissipation, 1.7 W for Vout = 8Vpp at Vd=6 V Rise Times <12 psec Hot Pluggable Package Size: 14.4 x 7 x 2 mm Measured Performance Bias conditions: Vd1,2,3 = 7 V, Idq = 310 mA, Vc1,2,3 = 0.7, 0.7, 0.8 V Typical 22 Gb/s, 0.48 Vpp Input, Vout = 8 Vpp. Primary Applications 40 GB/s Optical Market: DQPSK (2x) 100 GB/s Optical Market: DP-QPSK (4x) DQPSK Product Description The TriQuint TGA4943-SL is a three stage optical modulator driver amplifier designed to operate at frequencies that target the 28 Gb/s optical market using an 14.4 x 7 x 2 mm surface mount system in package (SIP). 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. Ev...
