6 / 12 page Pin Description PIN NAME FUNCTION 1 OUT Oscillator Output 2 SPRD Dither Enable. When the pin is high, the dither is enabled. When the pin is low, the dither is disabled. 3VCC Power Supply 4 GND Ground 5OE Output Enable. When the pin is high, the output buffer is enabled. When the pin is low, the output is disabled but the internal master oscillator is still on. 6 PDN Power-Down. When the pin is high, the master oscillator is enabled. When the pin is low, the master oscillator and the output buffer are disabled (power-down mode). 7 SDA I 2C Serial Data. This pin is for serial data transfer to and from the device. 8 SCL I 2C Serial Clock. This pin is used to clock data into and out of the device. 3.3V Center Spread-Spectrum EconOscillator™ 6 _____________________________________________________________________ 48 50 54 52 56 58 -40 10 -15 35 60 85 DUTY CYCLE vs. TEMPERATURE TEMPERATURE ( °C) 66MHz 50MHz 130kHz 33MHz VCC = 3.3V 48 50 54 52 56 58 DUTY CYCLE vs. SUPPLY VOLTAGE SUPPLY VOLTAGE (V) 2.7 3.0 3.3 3.6 66MHz 50MHz 130kHz 33MHz TA = +25 °C -90 -70 -80 -40 -50 -60 -10 -20 -30 0 44 48 46 50 52 54 56 SPECTRUM COMPARISON (120kHz BW, SAMPLE DETECT) FREQUENCY (MHz) NO SPREAD ±1% ±2% ±4% ±8% fMOSC = 50MHz, DITHER RATE = fMOSC / 4096 Typical Operating Characteristics (continued) (VCC = 3.3V, TA = +25 °C, unless otherwise noted.) |
