HMC727LC3C
v04.0514
14 Gbps, FAST RISE TIME
D-TYPE FLIP-FLOP
The HMC727LC3C is a D-Type Flip-Flop designed to
support data transmission rates of up to 14 Gbps, and
clock frequencies as high as 14 GHz. During normal
operation, data is transferred to the outputs on the
positive edge of the clock. Reversing the clock inputs
allows for negative-edge triggered applications.
All differential inputs to the HMC727LC3C are CML
and terminated on-chip with 50 Ohms to the positive
supply, GND, and may be DC or AC coupled. The
differential CMl outputs are source terminated to to 50
Ohms and may also be AC or DC coupled. Outputs can
be connected directly to a 50 Ohm ground-terminated
system or drive devices with CML logic input. The
HMC727LC3C operates from a single -3.3 V supply and
is available in ROHS-compliant 3x3 mm SMT package.

[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 GND. A
sufficient 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.
