Texas Instruments CDCE(L)913 Programmable Clock Synthesizers
Texas Instruments CDCE(L)913 Programmable Clock Synthesizers offer high-performance and low-cost. The devices generate up to three output clocks from a single input frequency. These outputs can be programmed in-system for any clock frequency up to 230MHz, using the integrated configurable PLL. Separate output supply pins are supplied on the CDCE(L)913 VDDOUT, which is 1.8V for CDCEL913 and 2.5V to 3.3V for CDCE913. The PLL supports SSC (spread-spectrum clocking) for better electromagnetic interference (EMI) performance. The Texas Instruments CDCE(L)913 operates in a 1.8V environment, with a temperature range of –40°C to 85°C.Features
