Functional Diagram

General Description

The HMC749LC3C is a T Flip-Flop w/Reset desig-

ned to support clock frequencies as high as 26

GHz. During normal operation, with the reset pin not

asserted, the output toggles from its prior state on the

positive edge of the clock. This results in a divide-by-

two function of the clock input. Asserting the reset

pin forces the Q output low regardless of the clock

edge state (asynchronous reset assertion). Reversing

the clock inputs allows for negative-edge triggered

applications.

All differential inputs to the HMC749LC3C 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 HMC749LC3C also

features an output level control pin, VR, which allows

for loss compensation or signal-level optimazation. the

HMC749LC3C operates from a single 3.3 V supply and

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