Notes
1.
A 3rd overtone crystal of 48 MHz must be used in combination with a filter connected to the oscillator output (XTAL2),
(L = 1.5

Strongly depends on the external decoupling capacitor connected to V

The audio information from the USB interface is fed directly to the ADAC.

APPLICATION INFORMATION
The UDA1321 is designed to be used as a self-powered device.
The I
2
C-bus EEPROM is optional and can be used e.g. to program your own Vendor ID and Product ID. In order to help
customers with defining there own configuration map, a special program called ‘Configuration map editor’ has been
developed. It is available from your local Philips Semiconductors Field Application Engineer.
More information about the firmware, descriptors and configurations can be obtained from several application notes.
