Functional Diagram
General Description
The HMC677G32 is a multi-function BiCMOS control
interface IC which is ideal for driving the gates of FET
and pHEMT based MMIC control devices. This unique
IC can be used to simplify the control of microwave
and millimeterwave transmit/receive modules, mili-
tary subsystems, and multi-throw/multi-port test
and measurement equipment. The HMC677G32
accepts serial or parallel data, and can drive up to 6
complementary sets of outputs.
The HMC677G32 also provides additional functionality
such as a power-up state selection, adjustable
output voltage levels, and a latched parallel control
mode which allows multiple control devices to share
a common data bus. The HMC677G32 is ideal for
controlling digital phase shifters, digital attenuators,
digital variable gain amplifiers, and switching matrices
embedded in complex microwave and millimeterwave
assemblies.

6-Bit SERIAL/PARALLEL SWITCH
DRIVER/CONTROLLER
Serial Control Interface
The HMC677G32 contains a 3-wire SPI compatible digital interface (DATA, CLK, LE). It is activated when P/S
is kept high. The 6-bit serial word must be loaded MSB first. The positive-edge sensitive CLK and LE requires
clean transitions. Standard logic families work well. When LE is high, 6-bit data in the serial input register is transferred
to the outputs. When LE is high CLK is masked to prevent data transition during output loading.
When P/S is low, 3-wire SPI interface inputs (DATA, CLK, LE) are disabled and the serial input register is loaded
asynchronously with parallel digital inputs (I0-I5). When LE is high, 6-bit parallel data is transferred.
For all modes of operations, the outputs will stay constant while LE is kept low.

Timing Diagram
(Latched Parallel Mode)
Parallel Mode (
Direct Parallel Mode & Latched Parallel Mode)
Note:
The parallel mode is enabled when P/S is set to low.
Direct Parallel Mode
- Outputs are changed by the Control Voltage Inputs directly. The LE (Latch Enable) must be at
a logic high to control in this manner.
Latched Parallel Mode
- Outputs are selected using the Control Voltage Inputs and set while the LE is in the Low
state. This will not change state while LE is Low. Once all Control Voltage Inputs are at the desired states the LE is
pulsed. See timing diagram above for reference.

Power-Up States
If LE is set to logic LOW at power-up, the logic state
of PUP1 and PUP2 determines the power-up state of
the part per PUP truth table. If the LE is set to logic
HIGH at power-up, the logic state of I5-I0 determines
the power-up state of the part per truth table. The
attenuator latches in the desired power-up state
approximately 200 ms after power-up.
Power-On Sequence
The required power-up sequence is: GND, Vdd, Vee,
Voph, Digital Inputs (I

- I

). The relative application
of input signal order of the digital inputs are not
important. Deviations from this sequence may
inadvertently forward bias ESD protection structures
and damage them. For added protection you may
install 2 kOhm resistors in series with each digital
input signal line, however these resistors will increase
the RC time constant.
