Detail

The DigRF v3 standard specifies a digital serial interface, which replaces the analog interface in previous generation mobile handset architectures. The DigRF v3 standard supports a variety of 3GPP air standards. The basic physical layer of DigRF v3 standard is implemented with a six wire interface. Independent transmit (Tx) and receive (Rx) differential signal pairs allow for concurrent bi-directional communication between the RF-IC and the BB-IC. SysClk and SysClkEn provide the timing references for digital serial data transmission and recovery. The DigRF v3 standard defines two basic packet types. Control packets are typically generated by the BB-IC for the purpose of configuring the RF-IC. Control packets are also utilized to communicate status between the RF-IC and the BB-IC. Digital IO data is transferred between the RF-IC and the BB-IC in DigRF v3 data packets. An analog or analogue signal is an allergy continuous in both time and amplitude. ...

Baseband is an adjective that describes signals and systems whose range of frequencies is measured from 0 to a maximum bandwidth or highest signal frequency; it is sometimes used as a noun for a band of frequencies starting at 0. ...

DigRF Testing

Test products and solutions must evolve to enable debug and characterization of DigRF v3 based components and mobile handsets. Test and measurement tools like spectrum analyzers and RF signal sources that have historically been used in the debug and characterize phase are necessary, but not sufficient to do the job on DigRF v3 based products. The air interface from the RF-IC still requires the traditional RF test and measurement tools. However, as the DigRF v3 interface standard replaces the analog interface between the RF-IC and the Baseband-IC, a spectrum analyzer can no longer measure this critical point in the system.
