• FMIN is selected when DVS in the serial data is set to 1.
• Input frequency: 10 to 160 MHz
Local
• The signal is passed through an internal divide-by-two prescaler and
17
oscillator
then input to the swallow counter.
signal input • The divisor can be set to a value in the range 272 to 65535. Since
the internal divide-by-two prescaler is used, the actual divisor will be
twice the set value.
• AMIN is selected when DVS in the serial data is set to 0.
• When SNS in the serial data is set to 1:
• Input frequency: 2 to 40 MHz
• The signal is input to the swallow counter directly.
Local
• The divisor can be set to a value in the range 272 to 65535. The
16
oscillator
set value becomes the actual divisor.
signal input • When SNS in the serial data is set to 0:
• Input frequency: 0.5 to 10 MHz
• The signal is input to a 12-bit programmable divider directly.
• The divisor can be set to a value in the range 4 to 4095. The set
value becomes the actual divisor.
