IDT8T53S111I

1:10 LVPECL Output Fanout Buffer IDT8T53S111I DATA SHEET General Description The IDT8T53S111I is a high-performance differential LVPECL fanout buffer. The device is designed for the fanout of high-frequency, very low additive phase-noise clock and data signals. The IDT8T53S111I 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 IDT8T53S111I ideal for those clock distribution applications demanding well-defined performance and repeatability. Two selectable differential inputs and ten low skew outputs are available. The integrated VREF voltage generator enables easy interfacing of single-ended signals to the device inputs. The device is optimized for low power consumption and low additive phase noise. Features Ten low skew, low additive jitter LVPECL outputs Two selectable, differential LVPECL clock inputs Differential pairs can accept the following differential input levels: LVDS, LVPECL and CML Maximum input clock frequency: 2.5GHz LVCMOS interface levels for the control input (input select) Output skew: 15ps (typical) Propagation delay: 250ps (typical) Additive phase jitter, RMS; fREF = 156.25MHz (12kHz - 20MHz): 30fs (typical) Full 3.3V and 2.5V supply voltage Maximum device current consumption (IEE): 126mA Lead-free (RoHS 6) 32-Lead VFQFN package -40°C to 85°C ambient operating temperature Block Diagram PCLK0 nPCLK0 Pulldown PU / PD PCLK1 nPCLK1 Pulldown ...
