MGCR01

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.

Table 3 - Prescaler Ratios

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.
