Spread Spectrum EMI Reduction Clocks | NB3H60113GH4
概览
The NB3H60113GH4, which is a member of the OmniClock family, is a one−time programmable (OTP), low power PLL−based clock generator that supports output frequency of 39.6 MHz. The device accepts fundamental mode parallel resonant crystal frequency of 19.8 MHz. It generates one single ended LVCMOS output. The output signal is modulated using the spread spectrum feature of the PLL (programmable spread spectrum type, deviation and rate) to meet demanding low electromagnetic interference (EMI). The device can be powered down using the Power Down pin (PD#). It is possible to program the internal input crystal load capacitance and the output drive current provided by the device. The device also has automatic gain control (crystal power limiting) circuitry which avoids the device overdriving the external crystal.
