Functional Diagram
General Description
the HMC759LP3e is a 7-bit BiCMos Digital
Attenuator in a low cost leadless sMt package. this
versatile digital attenuator incorporates off-chip AC
ground capacitors for near DC operation, making it
suitable for a wide variety of rF and IF applications.
the control interface is CMos/ttL compatible and
accepts a three wire serial input. the HMC759LP3e
features user selectable power up states and a serial
output port for cascading other Hittite serial controlled
components. the HMC759LP3e is housed in a
roHs compliant 3x3 mm QFn leadless package, and

Serial Control Interface
the HMC759LP3e contains a 3-wire
sPI compatible digital interface
(serIn, CLK, Le). the 7-bit serial
word must be loaded MsB first.
the positive-edge sensitive CLK
and Le requires clean transitions.
If mechanical switches are used,
sufficient debouncing should be
provided. When Le is high, 7-bit
data in the serial input register is
transferred to the attenuator. When
Le is high, CLK is masked to prevent
data transition during output loading.

If Le is set to logic LoW at power-up, the logic state
