All performance plots represent typical performance. Measurements for all performance plots were taken under the
following conditions, unless otherwise stated:
• VD = 2.5 V, VL = 3.3 V
• Serial Audio Input port set to slave
• Serial Audio Output port set to slave
• Input and output clocks and data are asynchronous
• XTI/XTO = 27 MHz
• Input signal = 1.000 kHz, 0 dBFS
• Measurement Bandwidth = 20 to (Fso/2) Hz
• Word Width = 24 Bits
