ICS843S104I-133

Crystal-to-LVPECL 133MHz Clock Synthesizer ICS843S104I-133 DATA SHEET General Description The ICS843S104I-133 is a PLL-based clock ICS synthesizer specifically designed for low phase noise HiPerClockS™ applications. This device generates a 133.33MHz differential LVPECL clock from an input reference of 25MHz. The input reference may be derived from an external source or by the addition of a 25MHz crystal to the on-chip crystal oscillator. An external reference is applied to the PCLK, nPCLK pins.The device offers spread spectrum clock output for reduced EMI applications. An I2C bus interface is used to enable or disable spread spectrum operation as well as to select either a down spread value of -0.35% or -0.5%.The ICS843S104I-133 is available in a lead-free 32-Lead VFQFN package. Features Four LVPECL output pairs Crystal oscillator interface: 25MHz Differential PCLK/nPCLK input pair PCLK/nPCLK supports the following input types: LVPECL, CML, SSTL Output frequenc...
