    产品信息

    描述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.特性Member of Programmable Clock Generator Family CDCE913/CDCEL913: 1-PLL, 3 Outputs CDCE925/CDCEL925: 2-PLL, 5 Outputs CDCE937/CDCEL937: 3-PLL, 7 Outputs CDCE949/CDCEL949: 4-PLL, 9 Outputs In-System Programmability and EEPROM Serial Programmable Volatile Register Nonvolatile EEPROM to Store Customer SettingsFlexible Input Clocking ConceptExternal Crystal: 8 MHz to 32 MHz On-Chip VCXO: Pull Range ±150 ppm Single-Ended LVCMOS Up to 160 MHzFree Selectable Output Frequency Up to 230  MHzLow-Noise PLL CorePLL Loop Filter Components Integrated Low Period Jitter (Typical 50 ps)Separate Output Supply Pins CDCE913: 3.3 V and 2.5 V CDCEL913: 1.8 VFlexible Clock Driver Three User-Definable Control Inputs [S0/S1/S2], for Example, SSC Selection, Frequency Switching, Output Enable, or Power Down Generates Highly Accurate Clocks for Video, Audio, USB, IEEE1394, RFID, Bluetooth®, WLAN, Ethernet™, and GPS Generates Common Clock Frequencies Used With TI-DaVinci™, OMAP™, DSPs Programmable SSC Modulation Enables 0-PPM Clock Generation1.8-V Device Power SupplyWide Temperature Range: –40°C to 85°CPackaged in TSSOPDevelopment and Programming Kit for Easy PLL Design and Programming (TI Pro-Clock™)APPLICATIONSD-TVs, STBs, IP-STBs, DVD Players, DVD Recorders, and PrintersAll other trademarks are the property of their respective owners
