Hyperstream IV modulator that produces a device that is well suited for all Audiophile and PRO Audio applications.
These features include TDM & SPI support as well as a Hardware (HW) mode for simplifying configuration of the ES9027PRO.
TDM / I2S / LJ / RJ / DSD / DoP & S/PDIF interfaces are supported.
Sample rates up to 768kHz with PCM data and DSD rates up to DSD1024 are supported. 7 selectable build-in digital filters are also available.
Configuration Modes
The ES9027PRO has 4 control programming modes. They are controlled by the state of the MODE (pin 17):
