NB3N65027
3.3V Programmable 3-PLL Clock
Synthesizer with
6 LVTTL/LVCMOS Outputs w/OE
The NB3N65027 is a LVCMOS PLLsynthesized clock generator.
It accepts a 10 MHz to 27 MHz clock or fundamental mode crystal as
the reference source and drives three independent, low noise
phaselocked loops (PLLs).
Control lines ACSx, BCSx and CCS will select their appropriate
bank output frequencies. ACS1 and BCS1 are twolevel
LVTTL/LVCMOS inputs, High and Low. ACS0, BCS0 and CCS are
threelevel LVCMOS inputs, High, Mid and Low.
The NB3N65027 has three independent LVTTL/LVCMOS output
banks of two outputs each. Banks A and B offer a 1X and a 1/2X
output. Using a 25 MHz crystal, the selectable output frequencies
range from 16 2/3 MHz to 133 1/3 MHz. A 12.5 MHz crystal offers
from 8 1/3 MHz to 66 2/3 MHz. In addition, the NB3N65027 will
generate a buffered reference LVTTL/LVCMOS output, REFOUT,
output frequencies. The OE pin, when set LOW, will disable the output
drivers to high impedance.
The NB3N65027 operates from a single +3.3 V supply across the
operating temperature range from 40
°C to +85°C, and is offered in a
QSOP20 RoHS compliant package.
The NB3N65027 provides the optimum combination of low cost,
flexibility, and high performance for Network, PCI and SDRAM
applications.
