MC1648数据手册恩XP中文资料规格书

描述 Description

The MC1648 requires an external parallel tank circuit consisting of the inductor(L) and capacitor(C). For Maximum Performance QL2100 at Frequency of Operation.

A varactor diode may be incorporated into the tank circuit to provide a voltage variable input for the oscillator (VCO). The MC1648 was designed for use in the Motorola Phase-Locked Loop shown in Figure 9.

This device may also be used in many other applications requiring a fixed or variable frequency clock source of high spectral purity.(See Figure 2) The MC1648 may be operated from a +5.0Vdc supply or a-5.2Vdc supply, depending upon system requirements.
