Data Sheet P10871EJ3V0DS00
PIN DESCRIPTIONS
Functions and Explanation
Input frequency from an external VCO output.
Must be coupled with capacitor (e.g. 1 000 pF) for DC cut.
Supply voltage 3.0
±
0.3 V for operation. Must be connected bypass
capacitor (e.g. 1 000 pF) to minimize ground impedance.
Divided ratio and modulus control can be governed by following input
data to these pins.
This frequency output can be interfaced to CMOS PLL.
Must be coupled with capacitor (e.g. 1 000 pF) for DC cut.
Must be connected to the system ground with minimum inductance.
Ground pattern on the board should be formed as wide as possible.
(Track length should be kept as short as possible).
ON/OFF-operation control can be governed by following input data to
this pin.
Must be connected bypass capacitor (e.g. 1 000 pF) to minimize
ground impedance.
