Description

The IDT8SLVD1204-33I is a high-performance differential LVDS fanout buffer. The device is designed for the fanout of high-frequency, very low additive phase-noise clock and data signals. The IDT8SLVD1204-33I is characterized to operate from a 3.3V power supply. Guaranteed output-to-output and part-to-part skew characteristics make the IDT8SLVD1204-33I 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.

For a 2.5 V version of this device, please refer to the 8SLVD1204I.

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).
