CDCEL949

The CDCEL949 is modular PLL-based low cost, high-performance, programmable clock synthesizers, multipliers and dividers. It generate up to 9 output clocks from a single input frequency. Each output can be programmed in-system for any clock frequency up to 230 MHz, using up to four independent configurable PLLs.The CDCx949 has separate output supply pins, VDDOUT, 1.8 V for the CDCEL949.

Features of the CDCEL949 are:(1)Member of Programmable Clock Generator Family CDCE913/CDCEL913: 1 PLLs, 3 Outputs CDCE925/CDCEL925: 2 PLLs, 5 Outputs CDCE937/CDCEL937: 3 PLLs, 7 Outputs CDCE949/CDCEL949: 4 PLLs, 9 Outputs; (2)In-System Programmability and EEPROM Serial Programmable Volatile Register Non-Volatile EEPROM to Store Customer Settings; (3)Highly Flexible Clock Driver Three User-Definable Control Inputs [S0/S1/S2] e.g. SSC-Selection, Frequency Switching, Output Enable or Power Down Generates Highly-Accurate Clocks for Video, Audio, USB, IEEE1394, RFID,Generates Common Clock Frequencies Used with TI DaVinci, OMAP, DSPs BlueTooth, WLAN, Ethernet and GPS Programmable SSC Modulation Enables 0-PPM Clock Generation.

The absolute maximum ratings of the CDCEL949 can be summarized as:(1)Supply voltage range :0.5 to 2.5 V; (2)Input voltage range(2) (3):0.5 to VDD + 0.5 V; (3)Output voltage range(2):0.5 to VDDOUT + 0.5 V; (4)Input current (VI < 0, VI > VDD): 20 mA; (5)Continuous output current :50 mA; (6)Storage temperature range :65 to 150 °C; (7)Maximum junction temperature :125 °C.
