ALC Datasheet, PDF – Alldatasheet

EAPD output low enable external amplifier 1: This register used to control the master volume of LFE and center output. S-OUT is the real surround output. Write 1 to clear this status bit. When this register is written, the bit values that come in on AC-Link will have no effect on read only bits and bit Vref is up to normal level 0: The 6th bit implementation is optional. Bit Type Function Stereo output with 5-bit volume control.

This register used to control the master volume of surround output. Cold, Warm and Register reset which listed below: External amplifier power down capability.

Drive GPIO0 as high. MX38 is the master volume control of surround output. GPIO0 is driven low by external device input. Not yet Analog Mixer Status 1: Analog Performance Characteristics Standard test condition: Writing 1xxxxx will be interpreted as x and respond when read with x as well. Intel Pentium 4 Proces Reading this register returns the ID code of the specific part.

Mono output is the same data sent on all output channels. GPIO1 datasheett driven low by external device input.

Sample Frequency in channel status By changing the values, sampling rates from to can be chosen. Mono output datqsheet 5-bit volume control. Read as 0 Depth control DP[ Combined rise or fall plus flight times are provided for worst case scenario modeling purpose.

Not yet ADC Status 1: And there is no gain for MX Enable Reserved Bit 13 is used to turn on 3D effects in both front and surround path.

Set GPIO1 as input pin. Bit Type Function 15 Reserved Bit 13 enables or disables 3D control.

A transaction which polarity depends on MX Not yet DAC Status 1: Bit 9 allows selection of mono output. The ALC Datasheeet provides two pairs of stereo outputs with independent volume controls, a mono output, and multiple stereo and mono inputs, along with flexible mixing, gain and mute functions to provide a complete integrated audio solution for PCs. Writing dataasheet will be interpreted as x and read as x Below is an example of differential CD input.


For this reason, when 6th bit is written by 1, it is equivalent to writing low 5-bit with 1. This register is used to adjust the sample rate. If validity control is set MX3A.

Note that the 3D bit in the general purpose register bit 13 must be set to 1 to enable this function. Bit 2 is used to select the clock source for the ALC Finally, datasehet PLL circuits generate required timing signals, eliminating the need for external clocking devices.

Locked R Ca [1: The clock source is The 3D stereo enhancement function provides for a deeper and datssheet sound experience with a potential 6-speaker arrangement. Bit 8 controls the mic selector.
