When interfacing to an MCU’s XTAL, the CLK Out is typically connected to the receiving IC’s X IN pin. The ULPPO oscillator output includes an internal driver. As a result, the output swing and operation is not dependent on capacitive loading. This makes the output much more flexible, layout independent, and robust under changing environmental and manufacturing conditions. Power Supply Connect to power supply 1.5V ≤ Vdd ≤ 3.63V.

The silicon oscillator technology enables a 32.768 kHz high-precision oscillator in the smallest footprint of 1.5x0.8mm housing. Typical core supply current is only 1 µA. And unlike standard oscillators, the ULPPO features programmable output swing, a factory programmable output that reduces the voltage swing to minimize power. HIGH-PRECISION FREQUENCY STABILITY OUTPUT VOLTAGE The ULPPO has two output voltage options. One option is a standard DC-coupled rail-to-rail LVCMOS output swing. The second option is the programmable output swing reduced swing output and current. Output swing is customer specific and factory programmed between 200 mV and 800 mV. For DC-coupled applications, output VOH and VOL are individually factory programmed to the customers’ requirement. VOH programming range is between 600 mV and 1.225V in 100 The ULPPO is factory calibrated over multiple temperature points to mV increments. Similarly, VOL programming range is between 350 guarantee extremely tight stability over temperature. Unlike quartz mV and 800 mV. For example; a PMIC or MCU is internally 1.8V logic crystals that have a classic tuning fork parabola temperature curve compatible, and requires a 1.2V VIH and a 0.6V VIL. Simply select with a 25°C turnover point with a 0.04 ppm/C temperature coeffi- ULPPO programmable output swing factory programming code to be cient, the ULPPO temperature coefficient is calibrated and corrected “D14” and the correct output thresholds will match the downstream over temperature with an active temperature correction circuit.

POWER SUPPLY NOISE IMMUNITY In addition to eliminating external output load capacitors common with standard XTALs, the ULPPO includes special power supply filtering and thus, eliminates the need for an external VDD bypassdecoupling capacitor to keep the footprint as small as possible. Internal power supply filtering is designed to reject more than ±150 mV noise and frequency components from low frequency to more than 10 + When the output is interfacing to an XTAL input that is internally AC-coupIed, the ULPPO output can be factory programmed to match the input swing requirements. For example, if a IC or MCU input is internally AC-coupIed and requires an 800mV swing, then simply choose the ULPPO programming code "AA8“ in the part number. It is important to note that the ULPPO does not include internal AC-coupling capacitors. Please see the Part Number Ordering section at the end of the datasheet for more information about the part number ordering scheme. MHz. START-UP AND STEADY-STATE SUPPLY CURRENT The ULPPO starts-up to a valid output frequency within 300 ms (180 ms typ). To ensure the device starts-up within the specified limit, make sure the power-supply ramps-up in approximately 10 - 20 ms ULPPO PROGRAMMABLE OUTPUT SWING Figure 2 shows a typical ULPPO output waveform (into a 10 pF load) when factory programmed for a 0.70V swing and DC bias (VOH/VOL) for (to within 90% of VDD).

The “ACcoupled” terminology refers to the programming description for applications where the downstream chipset includes an internal ACcoupling capacitor, and therefore, only the output swing is important and VOH/VOL are not relevant. For these applications, refer to Table 2 for the acceptable voltage swing options. When calculating no-load power for the ULPPO, the core and output driver components need to be added. Since the output voltage swing can be programmed for reduced swing between 250 mV and 800 mV, the output driver current is variable. Therefore, no-load operating supply current is broken into two sections; core and output driver. The equation is as follows: Total Supply Current (no load) = IDD Core + (65nA/V)(Voutpp) EXAMPLE 1: FULL-SWING LVCMOS + + + + IDD Core = 990nA (typ) Voutpp = 1.8V (LVCMOS) Idd Output Driver: (Cdriver)(Vout)(Fout) = (3.5pF)(1.8V)(32768Hz) = 206nA Supply Current = 990nA + 206nA = 1.2µA TABLE 2.
