NTE1536 Integrated Circuit CB Transceiver PLL Frequency Synthesizer
Description: The NTE1536 is a CMOS LSI device for the 27MHZ Citizen’s Band Transceiver. Function: The NTE1536 composes a Phase Lock Loop (PLL) frequency synthesizer system with only one crystal for an AM CB transceiver. Features: D Only one crystal is required for AM CB transceiver. D Two types of intermediate frequency can be selected: IF1 = 10.695MHZ IF2 = 9.785MHZ D Two types of lock monitor outputs: LM: When PLL is locked/unlocked, LM is high/low level. LM: When PLL is locked/unlocked, LM is low/high level. D The amplifier for low pass filter. D The amplifier for programmable counter input. D The detecting circuit for the mis–programming. D BCD code input to the programmable counter.
