Piscataway, NJ, November 16, 2011– MIPI Alliance today announced it has chartered the Analog Control Interface (ACI) Working Group and Envelope Tracking (ET) Subgroup to address the growing high data rate demands for mobile devices. The ACI Working Group will develop control interface specifications for analog chip-to-chip connections. The ET Subgroup will specifically address the interface between the transmitter and envelope tracking power supply.
