Low Phase Noise, Dual 1-to-6, 3.3V, 2.5V
LVPECL Output Fanout Buffer
8SLVP2106
DATA SHEET
General Description
The 8SLVP2106 is a high-performance differential dual 1:6 LVPECL
fanout buffer. The device is designed for the fanout of high-frequency,
very low additive phase-noise clock and data signals. The
8SLVP2106 is characterized to operate from a 3.3V or 2.5V power
supply. Guaranteed output-to-output and part-to-part skew
characteristics make the 8SLVP2106 ideal for those clock distribution
applications demanding well-defined performance and repeatability.
Two independent buffers with six low skew outputs each are
available. The integrated bias voltage references enable easy
interfacing of single-ended signals to the device inputs. The device is
optimized for low power consumption and low additive phase noise.

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is
mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equilibrium
has been reached under these conditions.
NOTE 1: Measured from the differential input crosspoint to the differential output crosspoint.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the differential crosspoints.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: Defined as skew within a bank of outputs at the same supply voltage and with equal load conditions. Measured at the differential
crosspoints.
NOTE 5: Defined as skew between outputs on different devices operating at the same supply voltage, same frequency, same temperature and
with equal load conditions. Using the same type of inputs on each device, the outputs are measured at the differential crosspoints.
NOTE 6: Characterized with input signal meeting the input edge rate minimum specification.
NOTE 7: For single-ended LVCMOS input applications, please refer to the Applications Information,
