ALED Audio Synchronization 7.3.3.1 Control of Audio Synchronization Table 4 describes the controls required for audio synchronization. ALED brightness control through serial interface is not available when audio synchronization is enabled. Table 4. Audio Synchronization Control (Registers 0Dh And 0Eh) NAME BIT DESCRIPTION GAIN_SEL[2:0] Register 0Dh Bits 7-5 Input signal gain control. Gain has a range from 0 dB to -46 dB. [000] = 0 dB, [001] = –6 dB, [010] = –12 dB, [011] = –18 dB, [100] = -24 dB, [101] = -31 dB, [110] = -37 dB, [111] = –46 dB DC_FREQ Register 0Dh Bit 4 Control of the high-pass filter's corner frequency: 0 = 80 Hz 1 = 510 Hz EN_AGC Register 0Dh Bits 3 Automatic gain control. Set EN_AGC = 1 to enable automatic control or 0 to disable. When EN_AGC is disabled, the audio input signal gain value is defined by GAIN_SEL. EN_SYNC Register 0Dh Bits 2 Audio synchronization enabled. Set EN_SYNC = 1 to enable audio synchronization or 0 to disable. SPEED_CTRL[1:0] Register 0Dh Bits 1-0 Control for refreshing frequency. Sets the typical refreshing rate for the ALED output [00] = FASTEST, [01] = 15 Hz, [10] = 7.6 Hz, [11] = 3.8 Hz THRESHOLD[3:0] Register 0Eh Bits 3-0 Control for the audio input threshold. Sets the typical threshold for the audio inputs signals. May be needed if there is noise on the audio lines. Table 5. Audio Input Threshold Setting (Register 0Eh) THRESHOLD[3:0] THRESHOLD LEVEL (mV, typical) 0000 Disabled 0001 0.2 0010 0.4 ... ... 1110 2.5 1111 2.7 |
