The device is designed for the fanout of high-frequency, very low additive phase-noise clock and data signals. The 8SLVP1212 is characterized to operate from a 3.3V and 2.5V power supply. Guaranteed output-to-output and part-to-part skew characteristics make the 8SLVP1212 ideal for those clock distribution applications demanding well-defined performance and repeatability. Two selectable differential inputs and twelve low skew outputs are available. The integrated bias voltage generators enables easy interfacing of single-ended signals to the device inputs. The device is optimized for low power consumption and low additive phase noise. Block Diagram Features • Twelve low skew, low additive jitter LVPECL outputs • Two selectable, differential clock inputs • Differential pairs can accept the following differential input levels: LVDS, LVPECL, CML • Maximum input clock frequency: 2GHz • LVCMOS interface levels for the control input (input select) • Output skew: 33ps (maximum) • Propagation delay: 550ps (maximum) • Low additive phase jitter, RMS at fREF = 156.25MHz, VPP = 1V, 12kHz–20MHz: 60fs (maximum) • Full 3.3V and 2.5V supply voltage • Device current consumption (IEE): 131mA (maximum) • Available in Lead-free (RoHS 6), 40-VFQFPN package • -40°C to +85°C ambient operating temperature • Differential PCLK0, nPCLK0 and PCLK1, nPCLK1 pairs can also accept single-ended LVCMOS levels.
