DESCRIPTION
TOLERANT
NAME NO.
AVDD 2 P 3.3-V analog power supply
3, 4,
AVSS P Analog supply ground
7
Active-low. A back-end error sequence is generated by applying logic
BKND_ERR 27 DI Pullup LOW to this terminal. BKND_ERR results in no change to any system
parameters while VALID2 goes low.
DVDD 11 P 3.3-V digital power supply
12,
DVSS 28, P Digital ground
29
DVSS_OSC 13 P Digital ground for oscillator
LRCLK 19 DI 5-V Pulldown Input serial audio data left/right clock (sampling rate clock)
MCLK is a 3.3-V clock master clock input. The input frequency of this
MCLK 8 DI 5-V Pulldown
clock can range from 4 MHz to 50 MHz.
Performs a soft mute of outputs, active-low (muted signal = a logic low,
normal operation = a logic high). The mute control provides a noiseless
MUTE 16 DI 5-V Pullup
volume ramp to silence. Releasing mute provides a noiseless ramp to
previous volume.
OSC_RES 14 AO Oscillator trim resistor
(1) TYPE: A = analog; D = 3.3-V digital; P = power/ground/decoupling; I = input; O = output
(2) All pullups are 20- µ A weak pullups, and all pulldowns are 20- µ A weak pulldowns. The pullups and pulldowns are included to ensure
proper input logic levels if the terminals are left unconnected (pullups = > logic 1 input; pulldowns = > logic 0 input). Devices that drive
inputs with pullups must be able to sink 20 µ A while maintaining a logic-0 drive level. Devices that drive inputs with pulldowns must be
able to source 20 µ A while maintaining a logic-1 drive level.
