Digital Interface

Analog Devices announces the release of HMC677LP5E within its Interface product line. This digital interface product is ideal for applications within the digital control sections of military EW, test and measurement equipment, and multi-function assemblies from DC to 110 GHz.

The HMC677LP5E 6-Bit serial/parallel switch driver/controller is a multi-function BiCMOS control interface IC which is ideal for driving the gates of FET and HEMT-based MMIC control devices. This unique IC can be used to simplify the control of microwave and millimeterwave transmit/receive modules, military subsystems, and multi-throw/multi-port test and measurement equipment. The HMC677LP5E accepts TTL/CMOS logic data in either 3-wire SPI or parallel format, and can drive up to six complementary sets of parallel outputs.

The HMC677LP5E provides additional functionality such as a power-up state selection, adjustable output voltage levels, and a latched parallel input mode which allows multiple switch driver/controllers to share a common parallel data bus. The HMC677LP5E is ideal for controlling MMIC-based digital phase shifters, attenuators and variable gain amplifiers, and switching matrices embedded in complex microwave and millimeterwave assemblies.
