NTE1536
Integrated Circuit
CB Transceiver PLL Frequency Synthesizer
Description:
The NTE1536 is a CMOS LSI device for the 27MH_Z 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 = 10.695MH_Z
IF₂ = 9.785MH_Z
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.
D The buffer output for the reference oscillator.
D The output for the half frequency of the reference oscillator.
D The reference frequency oscillation amplifier (with feedback resistance).
