• Manufacturer Part Number: CPLL66-4160
• Description: PLL/Synthesizer needing only an external frequency reference and supply voltages for the internal PLL (phase lock loop) and VCO
• Manufacturer: CRYSTEKMICROWAVE [CRYSTEK CORPORATION]

Introduction
The CPLL66 uses a simple 3 wire interface to program four internal registers. See Figure 1.
There are four 24 bit registers that need to be programmed. Which register is written into is
simply controlled by Control Bits C1 and C2. Table I summarizes the Truth Table for Control
Bits C1 and C2.
Table II shows the details of the four 24 bit registers.
