- ESD protection levels are 3000 V (HBM), 750 V (CDM), and 300 V (MM).
- Compatible with existing 32 kHz XTALs in the 2012 SMD package.
- Power supply and ground pins are conveniently placed for easy integration.
- Factory calibrated to ensure frequency stability of less than 20 ppm at room temperature and less than 100 ppm over the full temperature range.
- Stability degrades below 1.5V, reaching 250 ppm max between 1.2V and 1.5V.
- Internal power supply filtering eliminates the need for external bypass capacitors.
- Designed to reject AC noise greater than ±150 mVpp and beyond 10 MHz frequency component.
- Two output voltage options: standard LVCMOS and NanoDrive reduced swing.
- Output swing is programmable between 200 mV and 800 mV.
- Starts up to a valid output frequency within 300 ms.
- Power-supply ramp-up should be approximately 10-20 ms to ensure proper start-up.
The document details specifications for the YSO1533MK and NanoDrive™ output levels, with factory programmable VOH and VOL levels. Options include D26, D14, D74, and AA3, each with specific voltage swings and compatibility, nominal at 25°C with a tolerance of ±55 mV across Vdd and an operating temperature range of -40°C to 85°C.
Procedures for calculating load and no-load supply current are outlined. The total supply current without load is calculated using: Total Supply Current (no load) = Idd Core + (65nA/V)(Voutpp). Examples are provided for both full-swing LVCMOS and reduced swing NanoDrive™ configurations.
For calculating total supply current with load, the formula is: Total Current = Idd Core + Idd Output Driver (65nA/V*Voutpp) + Load Current (C*V*F). Examples illustrate the power reduction benefits of using a 1.8V logic compatible NanoDrive™ output voltage.
Table 1 lists acceptable VOH/VOL NanoDrive™ levels with corresponding voltage swings and comments on compatibility. Figures illustrate typical output waveforms and operating curves, including power supply noise rejection and frequency stability over temperature.
The document emphasizes understanding the power consumption characteristics of the YSO1533MK, particularly regarding the programmable output voltage swing and its impact on supply current. It also highlights the device's compatibility with different logic levels and its performance across a range of temperatures.
