Description



Features:

` Programmable Divider Divided by 3 to 255
` 10Bit Divider
` Phase Detector
` Reference Oscillation Circuit
` OnChip Filter Amplifier
` Code Converter
` Only two or three crystals required for CB radio AM frequency selection
` Unlocked signals are detected at instant stop "IS" terminal
` Two type program mode can be selected to change input mode level
  M: Low level . Binary code input enables, divided by 3 to 255
  M: High level . BCD code enables that the data at P1 to P6 port is offset 90 by code converter
` Internal active filter amplifier has a long holding time due to very high input impedance characteristics
  of the CMOSthis is to obtain very good spurious response.
` Output signal of the "I" can be used to stop the spurious radiation when the channel selector
  makes misprogramming such as rotary switch's lose contact.
` High speed and low power consumption due to CMOS
` Single power supply and fully TTL compatible: VDD = 5 ± 0.5 Volts
` Operating Temperature: TA = 30° to 65°C
` Pull down resistors installed in program and mode switch inputs
