Description
The TriQuint TGA4953-EPU 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 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
(1.1 W at Vo=6 V), very low rail ripple, high voltage drive
capability at 5V bias (6 V amplitude adjustable to 3 V), low
output jitter (10 ps typical), and low input drive sensitivity
(250 mV at Vo=6 V).
Primary Applications
•
Mach-Zehnder Modulator Driver for
Metro and Long Haul.

10.7 Gb/s, Vplus=5 V, Id=210 mA, (Pdc=1.1 Watt)
Vout=6 Vpp, CPC=50%, Vin = 500 mVpp
Scale: 2 V/div, 15 ps/div
The 4953 requires external DC blocks, a low frequency
choke, and control circuitry.
The TGA4953-EPU is available on an evaluation board.
Note: Devices designated as EPU are typically early in their characterization process prior to finalizing all electrical and process
specifications. Specifications are subject to change without notice.

Assure the combination of Vd and Id does not exceed maximum power dissipation rating.
When operated at this bias condition with a base plate temperature of 800C, the median life is reduced.
Assure Vctl1 never exceeds Vd1 and assure Vctrl2 never exceeds Vd2 during bias up and down sequences.
These ratings apply to each individual FET.
Junction operating temperature will directly affect the device median time to failure (MTTF). For maximum
life, it is recommended that junction temperatures be maintained at the lowest possible levels.
6/ These ratings represent the maximum operable values for the device.
Note: Devices designated as EPU are typically early in their characterization process prior to finalizing all electrical and process
specifications. Specifications are subject to change without notice.

Notes:
1. Based on a detailed thermal model of the output stage where channel temperature is highest.
Assumes worst case power dissipation condition (where no RF is applied at the input (no
power is dissipated in the load).
2. Thermal transfer is conducted thru the bottom of the TGA4953EPU package into the motherboard.
Design the motherboard to assure adequate thermal transfer to the base plate.

1. Disable the output of the PPG
1. Disable the output of the PPG
2. Set Vd=0V Vctrl1=0V Vctrl2=0 Vg1=0V
2. Set Vctrl2=0V
and Vg2=0V
3. Set Vd=0V
3. Set Vg1=-1.5V Vg2=-1.5V Vctrl1=-0.2V
4. Set Vctrl1=0V
4. Increase Vd to 5V observing Id.
5. Set Vg2=0V
- Assure Id=0mA
6. Set Vg1=0V
5. Set Vctrl2=+0.2V
- Id should still be 0mA
6. Make Vg1 more positive until Idd=65mA.
- This is Id1 (current into the first stage)
- Typical value for Vg1 is -0.65V
7. Make Vg2 more positive until Idd=220mA.
- This sets Id2T to 155mA.
- Typical value for Vg2 is -0.55V
8. Enable the output of the PPG.
- Set Vin=500mV
9. Output Swing Adjust: Adjust Vctrl2 slightly positive to increase output swing or adjust
Vctrl slightly negative to decrease the output swing.
- Typical value for Vctrl2 is +0.22V for
Vo=6V.
10. Crossover Adjust: Adjust Vg2 slightly positive to push the crossover down or adjust
Vg2 slightly negative to push the crossover up.
- Typical value for Vg2 is -0.57V to center
crossover with Vo=6V.
Note: Devices designated as EPU are typically early in their characterization process prior to finalizing all electrical and process
specifications. Specifications are subject to change without notice.
