The CDCE913PWR 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 230MHz, using the integrated configurable PLL.
The CDCx913 has separate output supply pins, VDDOUT, which is 1.8V for CDCEL913 and 2.5V to 3.3V 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.
