Analog Switch (1511 only)
The analog switch is useful for radio systems that utilize a frequency scanning mode and a narrow band mode The purpose of
the analog switch is to decrease the loop filter time constant allowing the VCO to adjust to its new frequency in a shorter
amount of time This is achieved by adding another filter stage in parallel The output of the charge pump is normally through the
Do pin but when LE is set HIGH the charge pump output also becomes available at BISW A typical circuit is shown below The
second filter stage (LPF-2) is effective only when the switch is closed (in the scanning mode)
TLW12340 – 25
Typical Crystal Oscillator Circuit
A typical circuit which can be used to implement a crystal
oscillator is shown below
TLW12340 – 26
Typical Lock Detect Circuit
A lock detect circuit is needed in order to provide a steady
LOW signal when the PLL is in the locked state A typical
circuit is shown below
TLW12340 – 27
