This manual introduces the related information of NJU6322 series products, including product overview, pin definition, electrical characteristics, package form, application circuits and attention points.
The NJU6322 series is a CMOS quartz crystal oscillator that integrates an oscillation amplifier, a 3‑stage divider and a 3‑state TTL‑compatible output buffer. It offers selectable output frequencies of fo, fo/2, fo/4 or fo/8 and operates up to 50 MHz with a symmetry of 45‑55%.
The document lists pin assignments, absolute maximum ratings, electrical characteristics such as supply voltage 0.5‑7.0 V, low operating current, and measurement circuits for signal rise/fall times. A note indicates that only the NJU6322K variant includes an oscillation‑stop function; other variants provide only output standby.
