General Description
The HMC677LP5(E) 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, military subsystems, and multithrow/ multiport test and measurement equipment. The HMC677LP5(E) accepts serial or parallel data, and can drive up to 6 complementary sets of outputs. The HMC677LP5(E) 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 HMC677LP5(E) 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 HMC677LP5(E) 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 ideal power-up sequence is: GND, Vdd, Vee, Voph, digital inputs. The relative order of the digital inputs are not important as long as they are powered after Vdd / Vee / Voph / GND.
