Description
Equivalent Circuit
18
CSD
Initial reset pulse generation and protection circuit
reference oscillator
Connect a capacitor between this pin and ground.
19
FGS
FG Schmitt trigger output
20
LD
Phase lock detection output
This output goes to the on state (low-level output)
in the phase locked state.
21
S/S
Start/stop control
Low : 0V to 1.0V
High : 2.0V to VREG
Hysteresis : about 0.25V
This pin goes to the high level when open.
A low level specifies the start state.
22
CLK
Clock input
Low : 0V to 1.0V
High : 2.0V to VREG
Hysteresis : about 0.25V
fCLK = 10kHz max.
If there is noise on this signal, insert a noise
rejection capacitor at this input.
