CDCLVC1310
Overview
The CDCLVC1310 is a highly versatile, low-jitter, lowpower clock fanout buffer which can distribute to ten low-jitter LVCMOS clock outputs from one of three inputs, whose primary and secondary inputs can feature differential or single-ended signals and crystal input. Such a buffer is good for use in a variety of mobile and wired infrastructure, data communication, computing, low-power medical imaging, and portable test and measurement applications.
- High-Performance Crystal Buffer With Ultralow Noise Floor of -169 dBc/Hz
- Additive Phase Noise/Jitter Performance Is 25 fsRMS (Typ.)
- Level Translation With 3.3-V or 2.5-V Core and 3.3-V, 2.5-V, 1.8-V, or 1.5-V Output Supply
- Device inputs consist of primary, secondary, and crystal inputs, and manually selectable (through pins) using the input MUX. The primary and secondary inputs can accept LVPECL, LVDS, HCSL, SSTL or LVCMOS signals and crystal input. - Crystal Frequencies Supported Are From 8 MHz to 50 MHz - Differential and Single-Ended Input Frequencies Supported Are up to 200 MHz
