Kajigar I dont know how to resolve themand I have checked my design circuits again and again,and I am sure that they are good,but the results is disappointed,how I do it? Bypass capacitors should be placed as close as possible to this pin and be connected directly to the ground plane. When LE goes HIGH, data stored in the shift registers datasehet loaded into one of the 3 appropriate latches control bit dependent. Binary Serial Data Input. The complementary input can be left. The oscillator input is driven from a reference oscillator.

Supply voltage can range from to 5. Features to 5. For connection of parallel resistor to the loop filter. See Section 1. Charge Pump Output.
For connection to a loop filter for driving the input of an external VCO. Charge Pump Ground. Analog Ground. RF Prescaler Complementary Input. A bypass capacitor should be placed as close as possible to this pin and be connected directly to the ground plane. The complementary input can be left unbypassed, with some degradation in RF sensitivity. RF Prescaler Input. Small signal input from the VCO. Analog Power Supply Voltage Input. Input may range from to 5.
Bypass capacitors should be placed as close as possible to this pin and be connected directly to the ground plane. I Oscillator Input. The oscillator input is driven from a reference oscillator. Digital Ground. I Chip Enable. Data for the various counters is clocked in on the rising edge into the bit shift register. Binary Serial Data Input.
Data entered MSB first. The last two bits are the control bits. High impedance CMOS input. When LE goes HIGH, data stored in the shift registers is loaded into one of the 3 appropriate latches control bit dependent. CMOS output. See Table 4. Digital Power Supply Voltage Input. Power Supply for Charge Pump.
Must be VCC. Recommended operating conditions indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits.
For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed.
Handling and assembly of this device should only be done at ESD protected work stations.
