Description:

The NTE1581 is a frequency divider manufactured by aluminum CMOS technology. It produces a frequency of 1/59719 or 1/88672 of the input frequency (3.58MHz to 60Hz or 4.43MHz to 50Hz).

Features:

• Makes Possible a Crystal Oscillator Circuit

• Capable of Handling Small−Amplitude Input Signals as low as 0.3Vpp

• Frequency−Dividing Ratio Selected Through Terminal N

• Reset Function

• Produces a Shaped−Waveform Output of the same Frequency as the Input Signal or Oscillation Output

• Derives a Vertial Scanning Frequency from TV Color Subcarrier

Applications:

• Frequency Divider for VTR
