DATASHEET
General Description
The IDT8SLVP1104I 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
IDT8SLVP1104I 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 IDT8SLVP1104I ideal for those clock
distribution applications demanding well-defined performance and
repeatability.Four low skew outputs are available. The integrated bias
voltage reference 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
• Four low skew, low additive jitter LVPECL differential output pairs
• Differential LVPECL input pair can accept the following differential
input levels: LVDS, LVPECL, CML
• Differential PCLKx pairs can also accept single-ended LVCMOS
levels. See the Applications section Writing the Differential Input
Levels to Accept Single-ended Levels (Figures 1 and 2)
• Maximum input clock frequency: 2GHz
• LVCMOS interface levels for the control input (input select)
• Output skew: 5ps (typical)
• Propagation delay: 320ps (maximum)
• Low additive phase jitter, RMS; f_REF = 156.25MHz, V_PP = 1V,
12kHz - 20MHz: 40fs (maximum)
• Maximum device current consumption (I_EE): 60mA (maximum)
• Full 3.3V or 2.5V supply voltage
• Lead-free (RoHS 6) packaging
• -40°C to 85°C ambient operating temperature
