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
occupies only 9 mm2.

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.
