Overview
Description
The 8SLVP1204 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 8SLVP1204 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 8SLVP1204 ideal for those clock distribution applications demanding well-defined performance and repeatability. Two selectable differential inputs and 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.

Description
Overview of IDT's 8LSVP (LVPECL) and 8SLVD (LVDS) families of low-jitter fanout buffers from IDT. Fanout buffers are a useful building block of many clock trees, providing signal buffering and multiple low-skew copies of the input signal. IDT's high-performance, low additive phase noise, differential clock fan-out buffers offer up to 2 GHz clock operation, low additive phase jitter (12kHz - 20MHz) of 50 to 100 femtoseconds RMS max, fast output rise & fall times (less than 150ps), and single and dual channel functions (dual: matched propagation delay). Presented by Baljit Chandhoke, Product Marketing Manager at Integrated Device Technology, Inc. To learn more about IDT's industry-leading portfolio of fanout buffers, visit Renesas's RF Buffer page.
