General Description

The HMC744LC3 is a 1:2 Fanout Buffer designed to

support data transmission rates up to 14 Gbps, and

clock frequencies as high as 14 GHz.

All differential inputs to the HMC744LC3 are CML and

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

Vcc, and may be AC or DC coupled. The differential

CML outputs are source terminated to 50 Ohms and may

also be AC or DC coupled. Outputs can be connected

directly to a 50 Ohm Vcc-terminated system, while DC

blocking capacitors may be used if the terminating

system is 50 Ohms to ground. The HMC744LC3 also

features an output level control pin, VR, which allows

for loss compensation or signal-level optimization. the

HMC744LC3 operates from a single 3.3 V supply and

is available in ROHS-compliant 3x3 mm SMT package.

Electrical Specifications, TA = +25 ºC, Vcc = 3.3 V, VR = 3.3 V
