The NB3H63143G is a one−time programmable (OTP), low power
PLL−based clock generator that supports any output frequency from
8 kHz to 200 MHz. The device accepts fundamental mode parallel
resonant crystal or a single ended (LVCMOS/LVTTL) reference clock
as input. It generates either three single ended (LVCMOS/LVTTL)

outputs, or one single ended output and one differential
(LVPECL/LVDS/HCSL/CML) output. The output signals can be

modulated using the spread spectrum feature of the PLL
(programmable spread spectrum type, deviation and rate) for
applications demanding low electromagnetic interference (EMI).
Individual output enable pins OE[2:0] are available to enable/disable

the outputs. Individual output voltage pins VDDO[2:0] are available
to independently set the output voltage of each output. Up to four
different configurations can be written into the device memory. Two
selection pins (SEL[1:0]) allow the user to select the configuration to
use. Using the PLL bypass mode, it is possible to get a copy of the
input clock on any or all of the outputs. 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
(Note: Microdot may be in either location)
(crystal power limiting) circuitry which avoids the device overdriving
the external crystal.
