Component and PCB Design PLL

The type and number of components required for assembly PLL are given in Table 1 below and the layout of components on the PCB can be examined in Figure 1 and the PCB as shown in Figure 2.

List of components.
Component parts primarily to the circuit loop filter and VCO circuit Is C1, C2, C3 and C4 is preferable to use Condensator NPO type C3, while for more preferred tantalum.

How to assembly

How to install the components on the PCB is recommended to use sequential order as the following :
1. Installation of voltage regulator
2. Installation of VCO and then in a state of components in other parts not yet installed pengecheckan held output at OUTPUT terminals. The frequency of the output should be located in between 13 ~ 14 MHz.
3. Installation of feedback oscillator, then the output frequency was observed at 3 and the TEST POINT fine tuner to start, he should be able to move between the frequency of up to 12,700 + 1KHz untill 12,700 - 1KHz.
4. Installation DEVIDER 1 (TC5082) and checked on the TEST POINT 1, the output frequency must exactly 10 KHz.
5. Installation DEVIDER 2 (TC4017) and checked on the TEST POINT 2, the output frequency must exactly 1 KHz.
6. Installation of programmable DEVIDER (TC9122) and the phase detector (TC5081). With all installed components, PLL must be locked in position thumb wheel or thumb wheel 000 not installed (LED should be extinguished). If not locked, then the L1 adjusted on ferrite so that the PLL can be locked.
7. Installation of thumb wheel and then dial 999 is placed in position, the LED should remain off, if not then the ferrite from the L1 reset. In other words the PLL to the design must can be locked from the frequency to 13,700 MHz to 14,699 MHz.
8. Furthermore thumb wheel 000 is set at the position, then dial the unit level increased by equivalent to the number 9 position as observed whether the increase of output frequency exactly 1 KHz. Unless appropriate increase the frequency of 1 KHz is not swayed. So done also for the tens dial and dial hundreds. Please note that each will hold a checking, always considered first whether the component is fully installed and already well construction. Important is whether the voltage at the IC pins and pad at the foot of the transistor is correct.
