9.9-12.5Gb/s Optical Modulator Driver
TGA4953-SL
OC-192 Metro and Long Haul Applications
Surface Mount Package
Key Features and Performance
• Metro MSA Compatible
• Wide Drive Range (3V to 10V)
• Single-ended Input / Output
• Low Power Dissipation
(1.1W at Vo = 6V)
• Very Low Rail Ripple
• 25ps Edge Rates (20/80)
• Small Form Factor
- 11.4 x 8.9 x 2 mm
Description
- 0.450 x 0.350 x 0.080 inches
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).
Primary Applications
• Mach-Zehnder Modulator Driver forwww.DataSheet.net/
Metro and Long Haul
• IRZ & Duobinary Applications
Measured Performance
TGA4953-SL Evaluation Board (Metro MSA Conditions)
10.7 Gb/s, Vdd = 5 V, Idd = 210 mA, (Pdc = 1.1W)
VOUT = 6 VPP, CPC = 50%, VIN = 500 mVPP
Scale: 2 V/div, 15 ps/div
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.

Table III Notes:
1/ Verified at package level RF test
2/ Typical Package RF Test Bias Conditions: Vdd = 5V, adjust VG1 to achieve Idd = 65mA then
adjust VG2 to achieve ID2T = 115 – 155 mA (Idd = 180 - 220mA), VCTRL1 = -0.2V & VCTRL2 =
+0.2 V
3/ Verified by design, SMT assembled onto a demonstration board detailed on sheet 6.
4/ VIN = 250mV, Data Rate = 10.7Gb/s, VD1 = VD2T or greater, VCTRL2 and VG2 are adjusted for
maximum output. Typical final Idd under drive ~ 220 mA.
5/ Computed using RSS Method where JRMS_DUT = √(JRMS_TOTAL2 - JRMS_SOURCE2)
6/ Verified at die level on-wafer probe
7/ Power Bias Die Probe: VTEE = 8V, adjust VG to achieve Idd = 175mA ±5%, VCTRL = +1.5V
Note: At the die level, drain bias is applied through the RF output port using a bias tee, voltage
is at the DC input to the bias tee
