| GSM Analog Interfacing Module (GAIM) PMB 2905 General Description The GSM Analog Interfacing Module (GAIM) is part of a chip set, which covers all functions of a mobile radio provided for the Global System for Mobile communications, GSM. A mobile terminal which contains this chip set will meet all performance requirements set down in the GSM recommendations for speech and data services. GAIM is provided for analog-to-digital and digital-to-analog conversion of baseband and voiceband signals as well. Moreover digital-to-analog conversion of an RF power control signal can be performed by this circuit. Type PMB 2905-F Features Package P-TQFP-64-1 (SMD) * Baseband receive A-to-D converter analog antialiasing filter (2nd order Bessel) 2nd order sigma-delta modulators for baseband receive and battery measurements * Baseband transmit D-to-A converter 10 bit switched-capacitor-type DAC analog postfilter (6 th order Bessel) * Power ramping control D-to-A converter 8-bit resistor-string-type DAC * Voiceband receive D-to-A converter low pass filter following digital --modulator on GOLD-SP two programmable earpiece gain stages * Voiceband transmit A-to-D converter 2nd order sigma-delta modulator analog antialiasing filter two programmable microphone gain stages * Package P-TQFP-64-1, 10 x 10 mm, 0.5 pitch * 3-V supply voltage ( 10 %) Battery RF Demodulator Battery RF Modulator PA Module Micro Phones Loud Speakers Switch Q Switch Q DAC DAC DAC ADC ADC Latches Latch ADC DAC Baseband Filters Block Diagram GMSK Modulators PA Control Voiceband Filters ITB08458 Siemens Aktiengesellschaft 1 |
