Part Description: MAX9471 2 DS

Part Details:

19-0524; Rev 1; 8/06 Multiple-Output Clock Generators with Dual PLLs and OTP MAX9471/MAX9472 General Description Features The MAX9471/MAX9472 multipurpose clock generators 5MHz to 50MHz Input Clock Reference are ideal for consumer and communication applica- Crystal or Input-Clock-Based Reference tions. The MAX9471/MAX9472 feature two bufferedphase-locked loop (PLL) outputs that can be indepen- Two Fractional-N Feedback PLLs (4MHz to dently set from 4MHz to 200MHz. These devices also 200MHz) with Buffered Outputs provide one (MAX9472) or two (MAX9471) buffered Two Buffered Outputs of Reference Clock outputs of the reference clock. OTP for Factory-Preset PLL Frequencies The MAX9471 outputs a set of MPEG/AC3 audio and Available (Contact Factory) video frequencies most commonly used in consumerapplications. The MAX9472 outputs a set of common Programmable Through I2C Interface or Three- audio frequencies. These frequencies are selected Level Logic Pins for Video or Audio Clocks through an I2C interface (MAX9471) or by setting the Low-RMS Jitter PLL (14ps for 45MHz) three-level FS pins. The MAX9471/MAX9472 feature a one-time-programmable (OTP) ROM, allowing one-time Integrated VCXO with ±200ppm Tuning Range programming of the two PLL outputs. Available in 20-Pin TQFN and 14-Pin TSSOP The MAX9471/MAX9472 include two basic configura- Packages tions. In one configuration, the OTP ROM sets PLL1 out- +3.3V Supply put to any frequency between 4MHz to 200MHz, and -40°C to +85°C Temperature Range the I2C interface (MAX9471) or programmable pins setthe PLL2 output frequency to a set of audio and videofrequencies. In the other configuration, the OTP ROM Ordering Information sets both PLL1 and PLL2 frequencies to fixed valuesbetween 4MHz to 200MHz. In both cases, the reference PIN- PKG PART TEMP RANGE output is available, but the OTP ROM can disable it. PACKAGE CODE The OTP ROM on the MAX9471/MAX9472 is factory set MAX9471ETP+** -40°C to +85°C 20 TQFN-EP* T2055-5 based on the customer requirements. Contact the factory M A X9 4 7 2 E U D + **
