DC ELECTRICAL CHARACTERISTICS

AGND = DGND = 0 V; all voltages with respect to 0 V.

Notes:

3.

Power-Down Mode is defined as RST = LOW with all clocks and data lines held static and no crystal
attached across XTI - XTO.

4.

Normal operation is defined as RST = HIGH. The typical values shown were measured with the digital
interface receiver in differential mode, serial audio output port 1 in master mode sourced by the SRC,
and serial audio output port 2 in master mode sourced by the AES3 receiver output.
