The Analog Control Interface Working Group is chartered to develop control interface specifications which impact analog chip-to-chip connections. In addition to the Working Group, an Envelope Tracking Subgroup has been formed to specifically address the interface between the transmitter and Envelope Tracking power supply.
The Envelope Tracking Subgroup's charter covers the following;
In June, 2011, the Board of Directors established an Investigation Group named the RFIC-to-PA IG. This action was taken in response to several member companies inquiring, "Do we need a unified specification for the RFIC-to-power amplifier control interface supporting Envelope Tracking?" The IG presented their findings to the Board in Vancouver in October 2011. The Board established an Analog Control Interface Working Group to address all analog interface needs, and the Envelope Tracking Subgroup to focus on specifying the interface between a Transmitter and ET power supply.
The ACI WG is currently working on drafting the envelope reference interface specification and a supporting application note. The ACI WG targets Q1 2013 for submitting specification draft to MIPI Alliance Board for review and approval. Specification release is expected a few months later in Q2 2013.
