The CDCE913 and CDCEL913 devices are modular PLL-based, low-cost, high-performance, programmable clock synthesizers. They generate up to three output clocks from a single input frequency. Each output can be programmed in-system for any clock frequency up to 230 MHz, using the integrated configurable PLL.
●The CDCx913 has separate output supply pins, VDDOUT, which is 1.8 V for CDCEL913 and 2.5 V to 3.3 V for CDCE913.
●The input accepts an external crystal or LVCMOS clock signal. A selectable on-chip VCXO allows synchronization of the output frequency to an external control signal.
●The PLL supports SSC (spread-spectrum clocking) for better electromagnetic interference (EMI) performance.
●The device supports nonvolatile EEPROM programming for easy customization of the device to the application. All device settings are programmable through the SDA/SCL bus, a 2-wire serial interface.
●The CDCx913 operates in a 1.8-V environment. It operates in a temperature range of –40°C to 85°C.
