Data Sheet P10872EJ3V0DS00
Input frequency from an external VCO output.
Must be coupled with capacitor (e.g. 1 000 pF) for DC cut.
Supply voltage 5.0 0.5 V for operation. Must be connected bypass capacitor
(e.g. 1 000 pF) to minimize ground impedance.
Divided ratio 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.
This pin 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.)
This pin must be connected bypass capacitor (e.g. 1 000 pF) to minimize ground
impedance.
