General Description

The NJU7512 is a 1200bps MSK (Minimum Shift Keying) modem IC, which operates from 1.8V power supply.It includes 14.7456MHz oscillator and selectable OSC buffer for an external output, and a frame detector for receiving.MSK modem is especially used for low power data communication, which requires high receiving sensitivity and noise susceptibility characteristics.
