RH-12/RH-28 System Module CCS Technical Documentation The antenna of the FM Radio is created with the headset. The wires of the headset are used as poles of the antenna. Only version TEA5767HN-VF1 and newer can be used. The previous versions have a 2.78V digital interface and need level shifters. While W/R (WRITE/READ) is HIGH the TIKU can transmit data to the TEA5767. At the rising edge of the Bus clock, the register shifts and accepts the stable bit. At clock low the TIKU writes the following bit.
RH-12/RH-28 System Module CCS Technical Documentation Interface to Engine This interface receives data from and transmits data to peripheral equipment. It transforms serial data to parallel data for the MCU or DSP and vice versa. The IAccIF IR interface is divided into two blocks, MIR and FIR. IR is a UART-based block for baud rates in the range 9600 bit/s to 115.2 kbit/s, and FIR is for the 1.152 Mbit/s rate. Both parts have the same physical connections so they cannot be used simultaneously.

RH-12/RH-28 System Module CCS Technical Documentation RF Module Introduction The RF module performs the necessary high frequency operations of the EGSM900/ GSM1800/GSM1900 triple band (EDGE) engine in the RH-12/RH-28 product. The EGSM900 is rematched to GSM850 in the RH-28 product. Both, the transmitter and receiver have been implemented by using direct conversion architecture, which means that the modulator and demodulator operate at the channel frequency.
RH-12/RH-28 System Module CCS Technical Documentation meallized frame and ground plane of the UI-board. RF Frequency Plan RF frequency plan is shown below. The VCO operates at the channel frequency multiplied by two or four, depending on the frequency band of operation. This means that the baseband-modulated signals are directly converted up to the transmission frequency and the received RF signals directly down to the baseband frequency.
RH-12/RH-28 System Module CCS Technical Documentation The seven regulators are named VR1 to VR7. VrefRF01 and VrefRF02 are used as the reference voltages for the Helgo, VrefRF01 (1.35V) for the bias reference and VrefRF02 (1.35V) for the RX ADC (analog-to-digital converter) reference. The regulators (except for VR7) are connected to the Helgo. Different modes of operation can be selected inside the Helgo according to the control information coming through the RFBus.
