HIGH SPEED LOGIC - SMT

3 - 1

The HMC721LP3E is a XOR/XNOR gate function

designed to support data transmission rates of up to 14

Gbps, and clock frequencies as high as 14 GHz.

All differential inputs to the HMC721LP3E are CML and

terminated on-chip with 50 Ohms to the positive supply,

GND, and may be DC or AC coupled. Outputs can be

connected directly to a 50 Ohm ground-terminated

system or drive devices with CML logic input. The

HMC721LP3E also features an ouput level control pin,

VR, which allows for loss compensation or signal level

optimization. The HMC721LP3E operates from a single

-3.3 V supply and is available in ROHS-compliant 3x3

mm SMT package..

[1] Reference this number when ordering complete evaluation PCB

[2] Circuit Board Material: Arlon 25FR or Rogers 4350

The circuit board used in the application should use

RF circuit design techniques. Signal lines should

have 50 Ohm impedance while the package gro-

und leads should be connected directly to the

ground plane similar to that shown. The exposed

package base should be connected to Vee. A suffi-

cient number of via holes should be used to connect

the top and bottom ground planes. The evaluation

circuit board shown is available from Hittite upon

request. Install jumper on JP1 to short VR to GND

for normal operation.
