The MG362x1A can provide phase modulation (ΦM) of the output signal using modulating signals from either its internal ΦM generator or an external source.

The MG362x1A has two ΦM operating modes—Narrow ΦM and Wide ΦM. In Narrow ΦM mode, the maximum ΦM deviation is the lesser of ±3 radians or ±5 MHz for DC to 8 MHz rates. In Wide ΦM mode, the maximum ΦM deviation is the lesser of ±400 radians or ±10 MHz for DC to 1 MHz rates.
