General Description
OPTICAL & MODULATOR DRIVERS - SMT
Low Additive RMS Jitter, <300 fs
The HMC871LC5 is a GaAs MMIC PHEMT Distributed Driver Amplifier packaged in a leadless 5x5mm
surface mount package. The amplifier operates
between DC and 20 GHz and provides 15 dB of
gain. The output swing cross point is adjustable
and saturated output swing is 4Vp-p. Gain flatness
is excellent at ±0.5 dB as well as very low additive
RMS jitter of 300 fs for 10 Gbps operation. The
HMC871LC5 provides VSR and Gigabit Ethernet
designers with scalable power dissipation for
varying output drive requirements (<0.25W at Vout =
2.5 Vp-p and <0.6W at Vout = 4 Vp-p). The HMC871LC5 has a very wide supply (Vdd) operating range
from +5V to +8V and the I/Os are internally matched to
50 Ohms.

[1]
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.

Application Circuit
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 4Vp-p output voltage swing, a 0.5Vp-p AC
coupled input voltage swing is required.
Device Power Up Instructions
1. Ground the device, no RF signal applied to device
2. Set Vgg to -2V (no drain current)
3. Set VC to +0.5V (no drain current)
4. Set Vdd to +5V or +8V (no drain current)
5. Adjust Vgg for Idd = 50mA (Vdd = 5V) or Idd = 75mA (Vdd = 8V)
6. Apply RF signal.
• 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 (±20%)
Device Power Down Instructions
1. Reverse the sequence identified above in steps 1 through 6.
