Philips Semiconductors Preliminary specification
Universal Serial Bus (USB) CODEC UDA1325
Notes
1. This value depends strongly on the application. The specified value is the typical value obtained using the application
diagram as illustrated in Fig.8.
2. At start-up of the OSCAD oscillator.
3. At start-up of the OSC48 oscillator.
4. Exclusive the IDDE current which depends on the components connected to the I/O pins.
