The HMC870LC5 is ideal for:
Wide Supply Range from 3.3V to 7V
• 10 Gbps NRZ MZ & Low VΠ Modulator Driver
Adjustable Output Amplitude: 2.5 to 8 Vp-p
• 10 Gbps RZ Transmission
Low Additive RMS Jitter, <300 fs
• 40 Gbps DQPSK
Low DC Power Consumption
1W for Vout = 8 Vp-p at Vdd = 7V
• Broadband Gain Block for
Test & Measurement Equipment
OPTICAL & MODULATOR DRIVERS - SMT
Cross Point Adjustment
• Military & Space
32 Lead 5x5mm SMT Package: 25mm²
Functional Diagram
General Description
The HMC870LC5 is a GaAs MMIC pHEMT Distributed Driver Amplifier packaged in a leadless 5x5 mm
surface mount package which operates between
DC and 20 GHz. The amplifier provides 17 dB of gain,
8Vp-p saturated output swing and features output
swing cross point adjustment. Gain flatness is excellent at ±0.5 dB as well as very low additive RMS jitter
of 300 fs for 10 Gbps operation. HMC870LC5 provides Metro and Long Haul designers with scalable
power dissipation for varying output drive requirements. (<0.4W at Vout = 3.6 Vp-p and <1W at Vout
= 8.5 Vp-p) The HMC870LC5 has a very wide supply
(Vdd) operating range from +3.3V to +7V, and the RF
I/Os are internally matched to 50 Ohms.

The circuit board used in the application should
use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the package
ground leads and package bottom should be
connected directly to the ground plane similar to
that shown. A sufficient number of via holes should
be used to connect the top and bottom ground
planes. The evaluation board should be mounted
to an appropriate heat sink. The evaluation circuit
board shown is available from Hittite upon request.

MZ OPTICAL MODULATOR
DRIVER, DC - 20 GHz
Device Operation
These devices are susceptible to damage from Electrostatic Discharge. Proper precautions should be observed
during handling, assembly and test.
The input to this device should be AC-coupled. To provide the typical 8Vp-p output voltage swing, a 1.2Vp-p
AC-coupled input voltage swing is required.
Device Power Up Instructions
1. Ground the device
2. Set Vgg to -2V (no drain current)
3. Set Vctl to +1V (no drain current)
4. Set Vdd to +5V (no drain current)
5. Adjust Vgg for Idd = 140mA
• Vdd may be increased to +7V if required to achieve greater output voltage swing.
• Vctl may be adjusted between +2V and +0V to vary the output voltage swing.
Device Power Down Instructions
1. Reverse the sequence identified above in steps 1 through 4.

• Vgg may be varied between -1V and 0V to provide the desired eye crossing point percentage (i.e. 50% crosspoint)
and a limited cross point control capability.
