27-BIT SEQUENCE
Conditions:
fosc = 750 MHz
Port register PUHF is ‘on’
Reference divider is set at 80
ICP =60 A
No test function.
Table 29 27-bit sequence
To change the oscillator frequency to 600 MHz in 50 kHz steps a 19-bit sequence or an 18-bit sequence can be used.
The charge pump current remains at 60
A.
