Normally connected to AGND with a large electrolytic capacitor and connected
to VREFL− with a 0.22µF ceramic capacitor.
Normally connected to AGND with a large electrolytic capacitor and connected
to VREFL+ with a 0.22µF ceramic capacitor.
This pin controls the calibration reference signal.
“L” :VCOML and VCOMR
“H” : Analog Input Pins (AINL±, AINR±)
“H” means the offset calibration cycle is in progress. Offset calibration starts
when RSTN pin goes “H”. CAL goes “L” after 8704 LRCK cycles for DFS pin =
“L”, 17408 LRCK cycles for DFS pin = “H”.
When “L”, the digital section is powered-down. Upon returning “H”, an offset
calibration cycle is started. An offset calibration cycle should always be initiated
after power-up.
MSB first, 2’s compliment.
SMODE2 SMODE1
When RSTN pin = “L” in master mode, LRCK outputs “L”.
