No.11069EBT07
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.

*1 Operating is not guaranteed.
*2 In the case of exceeding Ta = 25, 4.0mW should be reduced per 1.
*3 The radiation-resistance design is not carried out.
*4 Power dissipation is measured when the IC is mounted to the printed circuit board.
