HMC853LC3
v01.0614
28 GBPS, D-TYPE FLIP-FLOP
w/ PROGRAMMABLE OUTPUT VOLTAGE
The HMC853LC3 is a D-Type Flip-Flop designed to
support data transmission rates of up to 28 Gbps, and
clock frequencies as high as 28 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 HMC853LC3 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
HMC853LC3 also features an output level control pin,
VR, which allows for loss compensation or signal-level
optimazation. the HMC853LC3 operates from a single
3.3 V supply and is available in ROHS-compliant 3x3
mm SMT package.

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
metal package base must be connected to Vee. 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. Install jumper on JP1 to short
VR to GND for normal operation.
