It enables main LCDand small LCD with DSP IP pins.7. CSP1093CSP1093 integrates the timing and control functions for GSM 2+ mobile application with the ADC and DAC functions.The CSP1093 interfaces to the trident, via a 16-bit parallel interface. It serves as the interface that connects a DSP to theRF circuitry in a GSM 2+ mobile telephone. DSP can load 148 bits of burst data into CSP1093s internal register, andprogram CSP1093s event timing and control register with the exact time to send the burst. When the timing portion ofthe event timing and control register matches the internal quarter-bit counter and internal frame counter, the 148 bits inthe internal register are GMSK modulated according to GSM 2+ standards. The resulting phase information is translatedinto I and Q differential output voltages that can be connected directly to an RF modulator at the TXOP and TXON pins.The DSP is notified when the transmission is completed. For receiving baseband data, a DSP can program CSP1093sevent timing and control register with the exact time to start receiving I and Q samples through TXIP and TXIN pins.When that time is reached, the control portion of the event timing and control register will start the baseband receivesection converting I and Q sample pairs. The samples are stored in a double-buffered register until the register contains32 sample pairs. CSP1093 then notifies the DSP which has ample time to read the information out before the next 32sample pairs are stored. The voice band ADC converter issues an interrupt to the DSP whenever it finishes converting a16-bit PCM word. The DSP then reads the new input sample and simultaneously loads the voice band output DACconverter with a new PCM output word. The voice band output can be connected directly to a speaker via AOUTAN andAOUTAP pins and be connected to a Ear-mic speaker via AOUTBN and AOUTBP pins.8. X-TAL(13MHz)This system uses the 13MHz TCXO, TCO-9141B, Toyocom. AFC control signal form CSP1093 controls frequency from13MHz x-tal. It generates the clock frequency. This clock is inverted through NOT gate, TC7S04FU and is connected toCSP1093. 13MHz clock for YMU759 uses a not-inverted clock. Clock for RF parts uses same type.SAMSUNG Proprietary-Contents may change without notice
