Crystal-to-3.3V LVDS/LVCMOS 10-Output Clock Synthesizer ICS844S259I DATA SHEET The ICS844S259I is a 10 LVDS/LVTTL output clock synthesizer designed for instrumentation and wireless applications. The device generates 4 copies of a 125MHz, and 2 copies of a 100MHz differential LVDS clock 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. Four LVCMOS outputs duplicate the reference frequency and are provided for clock tree cascade purpose. 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 IDT’s third generation 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.
