The 48 MHz frequency is critical for USB 2.0 Hi-Speed applications, where the oscillator provides the reference clock for the USB PHY. The JO75 series features a stop function where pin 1 controls the oscillator output: when pin 1 is driven low (VIL less than 0.2 x VDC), the oscillator stops and the output goes to high impedance, reducing current consumption to 20uA max for power-saving modes. When pin 1 is open or driven high, the oscillator runs normally. The B stability code specifies \u00b150ppm total stability including tolerance at 25C, temperature variation over -20C to +70C, supply voltage change, aging, shock and vibration. The 15pF output load (code 1) is the standard for most CMOS clock inputs. The ceramic\/metal seam-sealed package ensures excellent hermeticity and long-term frequency stability with phase jitter below 1ps RMS.","working_principle":"The O 48.00000-JO75-B-3.3-1 LF operates as a crystal oscillator (XO) where an internal AT-cut quartz crystal resonator is combined with a sustaining amplifier and output buffer in a single package. The oscillator circuit maintains the crystal in continuous oscillation at its series resonant frequency of 48.000 MHz, with the amplifier providing the gain needed to compensate for crystal losses while maintaining the loop phase condition for stable oscillation. The output buffer converts the internal oscillator signal to HCMOS logic levels (VOH minimum 0.9 x VDC = 2.97V, VOL maximum 0.1 x VDC = 0.33V) suitable for driving standard CMOS clock inputs. The stop function on pin 1 operates by disabling the sustaining amplifier: when pin 1 is driven low (below 0.2 x VDC), the amplifier is turned off, the crystal stops oscillating, and the output buffer goes to high-impedance state. This allows system power management to shut down the clock during sleep modes, reducing supply current from 50mA to 20uA. The start-up time of 10ms maximum is the time from VDC exceeding the minimum threshold (or pin 1 going high) until the output achieves stable oscillation with correct frequency and amplitude.","pin_description":"
