Overview
NTE1254 Integrated Circuit Phase–Lock Loop (PLL) Frequency Synthesizer for CB
Features: D Programmable Divider – Divided by 3 to 255 D 10–Bit Divider D Phase Detector D Reference Oscillation Circuit D On–Chip Filter Amplifier D Code Converter D Only two or three crystals required for CB radio AM frequency selection D Unlocked signals are detected at instant stop “IS” terminal D 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 D Internal active filter amplifier has a long holding time due to very high input impedance chara...
