    3. TECHNICAL BRIEF 3. TECHNICAL BRIEF 3.1 Transceiver (SI4210, U401) The RF parts consist of a transmitter part, a receiver part, a digitally-controlled crystal oscillator. The Aero® II transceiver is a complete RF front end for multi-band GSM and GPRS wireless communications.
  • Page 15 3. TECHNICAL BRIEF (1) Receiver Part The Aero II transceiver uses a digital low-IF receiver architecture that allows for the on-chip integration of the channel selection filters, eliminating the external RF image reject filters, and the IF SAW filter required in conventional superheterodyne architectures.
  • Page 16 3. TECHNICAL BRIEF The ADC output is downconverted to baseband with a digital quadrature local oscillator signal. Digital decimation and FIR filters perform digital filtering, and remove ADC quantization noise, blockers, and reference interferers. The response of the FIR filter is programmable to a flat pass band setting (FILTSEL = 0, Register 08h) and a linear phase setting (FILTSEL = 1, Register 08h).
  • Page 17 3. TECHNICAL BRIEF Figure. 3-3 SI4210 TRANSMITTER PART (3) Digitally-controlled crystal oscillator The Aero II transceiver integrates the DCXO circuitry required to generate a precise system reference clock using only an external crystal resonator. The DCXO replaces a discrete VC-TCXO module. The DCXO allows for the use of a standard 26 MHz crystal, which reduces both cost and area compared to using a VCTCXO module.
  • Page 18 3. TECHNICAL BRIEF The Aero II transceiver can be configured in DCXO mode or VC-TCXO mode by the XMODE pin. To use the transceiver in DCXO mode, the XMODE pin is tied high. The XTAL1 and XTAL2 pins are then connected directly to the 26 MHz crystal.
