CD4750-Frequency synthesizer

CD4750 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4750 has a Frequency synthesizer

CD4750 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.

CD4750 Features

• Program range 6 1⁄ 2 decades, including up to 3 decades of Prescaler control.
• Division range extension by cascading.
• Built-in phase modulator.
• Fast lock feature.
• Out-of-lock indication.
• Low power dissipation and high noise immunity
