Part Manufacturer: Maxim


Part Description: MAX9491 DS - NEW

Part Details:

19-3942; Rev 0; 1/06 Factory-Programmable, Single PLL Clock Generator MAX9491 General Description Features The MAX9491 multipurpose clock generator is ideal for 5MHz to 35MHz for Crystal-Clock Reference communication applications. It offers a factory-program-mable PLL output that can be set to almost any frequency, 5MHz to 50MHz for a Driver Clock Reference ranging from 4MHz to 200MHz. The MAX9491 uses a One Fractional-N PLL with Buffered Output one-time-programmable (OTP) ROM to program the PLLoutput. The MAX9491 also features an integrated volt- 4MHz to 200MHz Output Frequency Range age-controlled crystal oscillator (VCXO) that is tuned by a Low RMS Jitter PLL (< 13ps) at 197 MHz DC voltage. The VCXO output is used as the PLL input.The VCXO has a wide ±200ppm (typ) tuning range. The Integrated VCXO with ±200ppm Tuning Range OTP on the MAX9491 is factory preset, based upon the Available in 14-Pin TSSOP and 20-Pin TQFN customer request.
