●Description
General-purpose VCO Series ICs (BU2373FV and BU2374FV) have a built-in VCO and phase comparator and facilitate the
configuration of a PLL system through the external connection of a LPF and frequency divider.
Furthermore, in order to facilitate the loop constant settings of the PLL system, the application manual has been enhanced to
ensure studies on the application.
●Features
1) The VCO enables midpoint settings within the range of oscillation through the external resistance.
2) The rising edge trigger type of phase comparator is built in.
3) Power-down mode setting can be made independently with the VCO and the phase comparator.
4) The VCO output frequency division can be selected on the SELECT pin.
5) Compact SSOP-B14 Package is adopted.
