RADIO FRONT END - BASEBAND (RF-BB) INTERFACE
The normative information in this standard is intended to provide a technical design team to construct the interface on a FED and a BED such that they will operate correctly with each other (at the interface level), when designed to this specification. Additional informative information is provided in the appendices to help illustrate the normative material. This document addresses the following interface topics: 1) RF-BB Electrical layer: time and amplitude specifications for lines, drivers, receivers, clocks; 2)RF-BB Link layer: bits, clock-data synchronization, power modes; 3) RF-BB Transport layer: data types, data framing, data bandwidth, connection to core IC; 4) RF-BB Interface Registers
This document defines a high-speed serial link that enables the bi-directional transfer of data and control information between the FED and BED. The document does not mandate the use of specific signaling, standard framing or standard messaging needed to make this an interoperable interface standard for RF devices or BB devices.
