TGA4954-SL

Advance Product Information April 4, 2006 9.9 - 12.5 Gb/s Optical Modulator Driver TGA4954-SL Wide Drive Range (3V to 10V) Single-Ended Input/Output Low Power Dissipation (1.1W @ 6Vo) Low Rail Ripple 25psec Edge Rates (20/80%) Hot-pluggable Package Dimensions: 11.4 x 8.9 x 2.0 mm (0.450 x 0.350 x 0.080 inches) Key Features and Performance Product Description The TriQuint TGA4954-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 4954 consists of two high performance www.DataSheet4U.com wideband amplifiers combined with off chip circuitry assembled in a surface mount package. A single 4954 placed between the MUX and Optical Modulator provides OEMs with a board level modulator driver surface mount solution. The 4954 provides Metro and Long Haul designers with system critical features such as: low power dissipation (1.2W at Vo = 6V), low rail ripple, high voltage drive capability at 5V bias (6 V amplitude adjustable to 3 V), low output jitter, and low input drive sensitivity (250mV at Vo = 6V). The 4954 requires external DC blocks, a low frequency choke, and control circuitry. Evaluation boards available upon request. Lead Free & RoHS compliant. 36 32 28 24 S21 (dB) 20 16 12 8 4 0 0 S21 S11 S22 Primary Applications Mach-Zehnder Modulator Driver Measured Data Vdd=5V; Id1=65mA; Id2=115mA; Vctrl1=-0.2V; Vctrl2=+0.2V 15 10 5 S11,S22 (dB) 0 -5 -10 -15 -20 -25 -30...
