NTE1536 IC CB Transceiver PLL Frequency Synthesizer

Formerly: ECG1536

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:
- Only one crystal is required for AM CB transceiver.
- Two types of intermediate frequency can be selected:
IF1 = 10.695MHZ
IF2 = 9.785MHZ
- 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.
- The amplifier for low pass filter.
- The amplifier for programmable counter input.
- The detecting circuit for the mis-programming.
- BCD code input to the programmable counter.
- The buffer output for the reference oscillator.
- The output for the half frequency of the reference oscillator.
- The reference frequency oscillation amplifier (with feedback resistance).
