Release 1.0 In addition, the base-band section integrates A/D and D/A converters which provide automatic on- chip correction of DC offsets. The three switched gain stages in each channel are DC coupled and provide 90dB gain control range with 2dB step size. The first PGA has a voltage gain range (x8-x1) with 6dB steps. -
Page 9: Vcxo Operation
Release 1.0 A secondary advantage of the OPLL is that the output signal, coming from a VCO, is truly constant envelope. This removes the problem of spectral spreading caused by AM to AM and AM to PM conversion in the power amplifier. The OPLL is formed from an on chip Gilbert cell down converter, limiter and phase detector with on chip passive loop filter. -
Page 10: Logic (Base-Band)
6 Logic (Base-Band) Introduction: E61 utilizes TI’s chipsets (CALYPSO and IOTA) and RENESAS’s chipset (SHJ2SLSL) as base- band solution. Base-band is composed with three potions: Logic, Analog/Codec and MMP. CALYPSO is a GSM/GPRS digital base-band logic solution included microprocessor, DSP, and peripherals. - Page 11 Release 1.0 IOTA 06/2006 Technical Documentation TTD_Repair_L3 _Theory of Operation_E61_R1.0.pdf Page 11 of 33...

Page 12: Calypso
In E61, we implement software flow control by only two signals: TXD0 and RXD0. General Purposes I/O (GPIO) Calypso provides 16 GPIOs configurable in read or write mode by internal registers. In E61, we utilize all of them as follows: IO0: Let MMP power-on reset;... - Page 13 It also provides 6 chip-select signals corresponding each to an address range of 8 mega bytes. One of these chip-select is dedicated to the selection of an internal memory. In E61, we employ nCS0/nCS1 (nCS0_NROM/nCS1_NROM) for external Flash and nCS2 (nCS2_NSRAM) for external SRAM.
- Page 14 The parallel interface allows control 13 external individual outputs and 1 internal signal with a time accuracy of the quarter of GSM bit. These parallel signals are mainly used to control the RF activity. In E61, we employ 7 of them to control RF activity. TSPACT1:...

Page 15: Iota
Release 1.0 6.2 IOTA Together with a digital base-band device (Calypso), IOTA is part of a TI DSP solution intended for digital cellular telephone applications including GSM 900, DCS 1800 and PCS 1900 standards (dual band capability). It includes a complete set of base-band functions to perform the interface and processing of voice signals, base-band in-phase (I) and quadrature (Q) signals which support single-slot and multi- slot mode, associated auxiliary RF control features, supply voltage regulation, battery charging control and switch ON/OFF system analysis. - Page 16 Release 1.0 Automatic Power Control (APC) Purpose of the Automatic Power Control (APC) is to generate an envelope signal to control the power ramping up, ramping down and power level of the radio burst. The APC structure is intended to support single slot and multi-slots transmission with smooth power transition when consecutive bursts are transmitted at different power level.
- Page 17 Release 1.0 SIM card shifters (SIMS) The SIM card digital interface in ABB insures the translation of logic levels between DBB and SIM card, for transmission of 3 different signals; a clock derived from a clock elaborated in DBB, to the SIM card (DBBSCK SIMCLK).
- Page 18 Release 1.0 Battery charger Interface (BCI) The main function of the ABB charger interface is the charging control of either a 1-cell Li-ion Battery or 3-serie Ni-MH cell batteries with the support of the micro-controller. The battery monitoring uses the 10 bit ADC converter from the MADC to measure the battery voltage, battery temperature, battery type, battery charge current, battery charger input voltage.
