Function
Description of Function
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.

Output
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.
