The CPLL66 uses a simple 3 wire interface to program four internal registers. See Figure 1. Table II shows the details of the four 24 bit registers. Figure 1. Timing Diagram

When using the CPLL66 family in a synthesizer application, all four 24 bit registers need to be written into after power-up. After writing all four latches the first time, subsequent frequency step changes can be accomplished by changing the N Counter Latch only. Page 5 of 6 0.60" SQ SMD CPLL66-2175-2175 Table II.

Programming Crystek p/n: CPLL66-2175-2175 The following is specific programming for CPLL66-2175-2175 (2.175GHz fixed freq. with 100KHz Step Size and 10MHz input reference frequency). Program all three registers with the following: Function Latch: 9F8083 H N Counter Latch: 02A759 H R Counter Latch: 000190 H The above values will set the CPLL66-2175-2175 to 2.175GHz Page 6 of 6 0.60" SQ SMD CPLL66-4240-4240
