NB3H63143G

3.3 V / 2.5 V Programmable

OmniClock Generator

with Single Ended (LVCMOS/LVTTL) and

Differential (LVPECL/LVDS/ HCSL/CML)

Outputs with Individual Output Enable

and Individual VDDO

The NB3H63143G, which is a member of the OmniClock family, 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

(crystal power limiting) circuitry which avoids the device overdriving

the external crystal.
