Preliminary Information SATURN Electrical Characteristics (Mode Control) Description ENAVLE STARTUP MODE CDMA BAND 1900 Conditions Standby Mode 0 0 X X All circuits powered down except logic inputs Start up Mode 0 1 X 1 For high band IF (210.38MHz) 0 1 X 0 For low band IF (85.38MHz) Turns on VCO circuits, DLL quadrature generation, prescaler and IQ demodulator. All other circuits remain powered down CDMA mode 1 1 1 1 For high band IF (210.38MHz) 1 1 1 0 For low band IF (85.38MHz) All circuits operational except for IF output buffer, CDMA input stage selected. FM Mode 1 1 0 0 All circuits operational except for IF output buffer, FM input stage selected. Alternative FM mode 1 1 0 1 Note 4 CDMA IF AGC 1 0 1 X Demodulator and LO only mode generation circuitry powered down. IF output buffer enabled FM IF AGC 1 0 0 X Demodulator and LO generation circuitry powered down. IF output buffer enabled. X = Don’t Care Notes 1. STARTUP mode is provided to allow VCO/DLL/prescalers to stabilise before signal path is activated. This is a power-saving feature since the signal path is redundant during this period. If this feature is not required, the ENABLE and STARTUP control pins can be shorted together so that all circuitry is activated at the same time. 2. In high band mode (Band 1900 = 1) the VCO operates at twice the IF frequency. For example if IF = 210.38MHz then the oscillator operates at 420.76MHz. A delay locked loop (DLL) circuit then generates the quadrature LO signals. The prescaler output, VHFBUF, is VCO frequency divided by 8 (52.494MHz). 3. In low band mode (Band 1900 = 0) the VCO operates at 4 times the IF frequency. for example if IF = 85.38MHz the oscillator operates at 341.52MHz. This is then divided and uses DLL circuit to provide the quadrature LO signals. The prescaler output, VHFBUF, is VCO frequency divided by 8 (42.69MHz). 4 This mode can be used for FM. The VCO operates at twice the LO frequency. This mode is not normally used as a large tuning range is required on the VCO. Prescaler output is LO frequency divided by four.
