Dual 1:2, LVDS Output Fanout Buffer 8SLVD2102 Datasheet Description Features The 8SLVD2102 is a high-performance differential dual 1:2 LVDS Two 1:2, low skew, low additive jitter LVDS fanout buffers fanout buffer. The device is designed for the fanout of high-frequency, Two differential clock inputs very low additive phase-noise clock and data signals. The Differential pairs can accept the following differential input 8SLVD2102 is characterized to operate from a 2.5V power supply. levels: LVDS and LVPECL Guaranteed output-to-output and part-to-part skew characteristics make the 8SLVD2102 ideal for those clock distribution applications Maximum input clock frequency: 2GHz demanding well-defined performance and repeatability. Output bank skew: 15ps (maximum) Two independent buffers with two low skew outputs each are Propagation delay: 300ps (maximum) available. The integrated bias voltage generators enables easy interfacing of single-ended signals to the device inputs. The device is Low additive phase jitter: 200fs, RMS (maximum) optimized for low power consumption and low additive phase noise. f = 156.25MHz, V = 1V, V = 1V, REF PP CMR Integration Range 10kHz - 20MHz 2.5V supply voltage Maximum device current consumption (I ): 90mA DD Lead-free (RoHS 6) 16-Lead VFQFPN package -40C to 85C ambient operating temperature Block Diagram Pin Assignment V DD QA0 nQA0 PCLKA 16 15 14 13 1 12 nQA1 GND nPCLKA QA1 nQA1 11 2 QA1 EN 8SLVD2102I 10 nQA0 3 PCLKB 8XXXXXX V DD QB0 nQB0 9 QA0 4 PCLKB nPCLKB 5 6 78 nPCLKB QB1 nQB1 Voltage V REF Reference 1616-pin,-pin, 33.0mm.0 x 3.0x m3.0mmm VFQFPNVFQFN PPacackagekage V DD EN 8SLVD2102 January 21, 2018 1 2018 Integrated Device Technology, Inc.
