Dual 1:8, 3.3V, 2.5V LVPECL Output Fanout Buffer
The IDT8SLVP2108I is a high-performance differential dual 1:8 LVPECL fanout buffer. The device is designed for the fanout of high-frequency, very low additive phase-noise clock and data signals. The IDT8SLVP2108I 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 IDT8SLVP2108I ideal for those clock distribution applications demanding well-defined performance and repeatability. Two independent buffers with eight 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.
