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. 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. 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.

DLL and Prescaler divide ratios The BAND 1900 and DIV2 EN inputs allow the overall divide ratio to control the total divide ratio in MGCR01 as shown in the following table. Notes: if DIV2 EN is set low then the total divider ratio is always 8. If DIV2 EN is set high then the prescaler divide ratio is always 2. For example with BAND 1900 high and if the oscillator frequency is 300MHz, then the DLL output (the mixer LO frequency) will be 150MHz and the prescaler output will be 75MHz. Electrostatic handling precautions must be applied.
