A good PCB layout for the DS1340Z-33+T&R involves keeping the crystal oscillator circuitry away from noisy digital signals, using a solid ground plane, and minimizing trace lengths and widths to reduce parasitic inductance and capacitance.
To ensure reliable startup, make sure the power supply is stable and within the recommended range, the crystal oscillator circuit is properly biased, and the load capacitance is within the recommended range (15pF to 30pF).
The maximum frequency deviation of the DS1340Z-33+T&R oscillator over temperature (-40°C to 85°C) and voltage (2.7V to 5.5V) is ±100 ppm.
Yes, the DS1340Z-33+T&R can be used in battery-powered devices. The typical current consumption is 1.5µA at 3V and 25°C, making it suitable for low-power applications.
To troubleshoot issues, check the power supply, crystal oscillator circuit, and load capacitance. Verify that the crystal is properly connected and not damaged. Use an oscilloscope to measure the oscillator output and verify the frequency.
