Texas Instruments  CDCE813QPWRQ1

The CDCE813-Q1 device is a modular Phase-locked-loop-based (PLL), low-cost,high-performance, programmable clock synthesizers. They generate up to three output clocks from asingle input frequency. Each output can be programmed in-system for any clock frequency up to230 MHz, using the integrated configurable PLL.

The CDCE813-Q1 has separate output supply pins, VDDOUT, providing2.5 V to 3.3 V.

The input accepts an external crystal or LVCMOS clock signal. A selectable on-chip VCXOallows 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 deviceto the application. All device settings are programmable through the I2C bus, a 2-wire serialinterface.

The CDCE813-Q1 operates in a 1.8-V core environment as well as eliminating the need foradditional, independent XTAL oscillators which reduces component count and board size. It operatesin a temperature range of –40°C to 105°C.
