For the smallest 32 kHz XO in CSP (1.2mm2), consider the YSO1532MK 2. Measured peak-to-peak. TestedwithAgilent53132Afrequencycounter. Duetothe lowoperatingfrequency,thegatetime must be >100 mstoensure an accurate frequency measurement. 3. Stability is specified fortwo operating voltage ranges. Stability progressively degrades with supplyvoltage below 1.5V. Measured peak-to-peak. Inclusiveof Initial Tolerance at 25°C, and variations over operating temperature, rated power supply voltage and load. 4. Core operating current does not include output driver operating current or load current. To derive total operating current (no load), add core operating current + (0.065 pA/V) * (peak-to-peak output Voltage swing). 5. Measured from the time Vdd reaches 1.5V.

Figure 2. YSO1533MK Footprint Compatibility with Quartz XTAL Footprint [6] Frequency Stability The YSO1533MK is factory calibrated (trimmed) to guarantee frequency stability to be less than 20 ppm at room temperature and less than 100 ppm over the full -40°C to +85°C temper-ature range. Unlike quartz crystals that have a classic tuning fork parabola temperature curve with a 25°C turnover point,the YSO1533MK temperature coefficient is extremely flat across temperature. The device maintains less than 100 ppm frequency stability over the full operating temperature range when the operating...

Example part number:O201232768KSD144MI • Voh = 1.1V, Vol = 0.4V (VSw = 0.70V) Calculating Load Current No Load Supply Current When calculating no-load power forthe YSO1533MK, the core and output driver components need to be added. Since the output voltage swing can be programmed for reduced swing between 300 mV and 700 mV, the output driver current is...
