Description

The 8V44S269 is a ten LVDS/LVTTL output clock synthesizer designed for instrumentation and wireless applications. The device generates four copies of a 125MHz, two copies of a 100MHz differential LVDS clock, and one 50MHz (LVCMOS) signal with excellent phase jitter performance. The PLL is optimized for a reference frequency of 25MHz. Both a crystal interface and a single-ended input are supported for the reference frequency. Three LVCMOS outputs duplicate the reference frequency and are provided for clock tree cascade purposes. Each of the four LVCMOS outputs can be supplied with either 3.3V, 2.5V, or 1.8V, forming the respective LVCMOS output levels of 3.3V, 2.5V, or 1.8V. The device uses Renesas' third-generation FemtoClock® technology for an optimum of high clock frequency and low phase noise performance, combined with a low power consumption. The device supports a 3.3V voltage supply and is packaged in a small, lead-free (RoHS 6) 48-lead VFQFN package.
