2.5V, 3.3V Differential 1:8
HCSL Fanout Buffer
Description
The NB3L208K is a differential 1:8 Clock fanout buffer with
High−speed Current Steering Logic (HCSL) outputs. Inputs can
directly accept differential LVPECL, LVDS, and HCSL signals.
Single−ended LVPECL, HCSL, LVCMOS, or LVTTL levels are
accepted with a proper external Vth reference supply per Figures 4
and 6. The input signal will be translated to HCSL and provides eight
identical copies operating up to 350 MHz.

MARKING
DIAGRAM
1
The NB3L208K is optimized for ultra−low phase noise, propagation
delay variation and low output–to–output skew, and is DB800H
compliant. As such, system designers can take advantage of the
NB3L208K’s performance to distribute low skew clocks across the
backplane or the motherboard making it ideal for Clock and Data
distribution applications such as PCI Express, FBDIMM, Networking,
Mobile Computing, Gigabit Ethernet, etc.
Output drive current is set by connecting a 475 W resistor from
IREF (Pin 27) to GND per Figure 11. Outputs can also interface to
LVDS receivers when terminated per Figure 12.

26.Measured with oscilloscope, averaging off, using min max statistics. Variation is the delta between min and max.
27.Matching applies to rising edge rate for clock and falling edge rate for Clock#. It is measured using a ©75 mV window centered on the average
crosspoint where clock rising meets Clock# falling. The median crosspoint is used to calculate the voltage threshold the oscilloscope is to
use for the edge rate calculations.

31.Measured from differential cross−point to differential cross−point with scope averaging on to find mean value.
32.The differential input clock is expected to be sourced from a high performance clock oscillator.

NB3L208K
Figure 3. Typical Phase Noise Plot at fcarrier = 156.25 MHz at an Operating Voltage of 3.3 V, Room Temperature
The above phase noise data was captured using Agilent
E5052A/B. The data displays the input phase noise and
output phase noise used to calculate the additive phase jitter
at a specified integration range. The additive RMS phase
jitter contributed by the device (integrated between 12 kHz
and 20 MHz) is 45.7 fs.
To obtain the most accurate additive phase noise
measurement, it is vital that the source phase noise be
notably lower than that of the DUT. If the phase noise of the
source is similar or greater than the device under test output,
the source noise will dominate the additive phase jitter
calculation and lead to an artificially low result for the
additive phase noise measurement within the integration
range.
The additive RMS phase jitter performance of the fanout
buffer is highly dependent on the phase noise of the input
source.

37.The outputs are tri−stated, but the termination networks pull them low
38.OE# pins are asynchronous asserted−low signals.
39.Each OE# pin controls two pair of DIF outputs.
OE# Assertion (Transition from ‘1’ to ‘0’)
OE# De−Assertion (Transition from ‘0’ to ‘1’)
The maximum latency from the de−assertion to tristated
(low due to termination pull down) outputs is 12 DIF clock
periods.
All differential outputs that were tri−stated (low due to
termination pull down) will resume normal operation in a
glitch free manner. The latency from the assertion to active
outputs is 4 − 12 DIF clock periods.
Note: Input clock must remain running for a minimum of
12 clock cycles.
