The MADR-010269-DIE is a CMOS driver designed to work with MACOM’s digital attenuators and phase shifters. It translates 3.3 V or 5.0 V CMOS inputs to negative gate control voltages.
This driver offers 6-bit serial and parallel control interface. The serial control interface is compatible with the SPI protocol. SEROUT is the SERIN delayed by 6 clock cycles which can be used in daisy-chain operation. Complementary 0 V / -5 V outputs provide up to 1 mA bias current.
