4.2.1.5

LDO_SVNS_1P8

1.8 V LDO from coin cell to generate 1.8 V power for SNVS and 32 K RTC. The LDO_SNVS_1P8

regulator implements a fixed linear-regulator function from VDD_SNVS_IN (see Table 9 for minimum

and maximum input requirements). The typical output is 1.7 V. It is intended for use with the internal

SNVS circuitry and 32 K RTC. For additional information, see the i.MX 7Dual Application Processor

Reference Manual (IMX7DRM).

On-chip oscillators

4.4.1

OSC24M

Power for the oscillator is supplied from a clean source of VDDA_1P8. This block implements an

amplifier that when combined with a suitable quartz crystal and external load capacitors implements an

oscillator. The oscillator is powered from VDDA_1P8.
