The ALC will return any uninstalled bits or registers with 0 for the read operation. Write 1 to clear this status bit. Reading this register returns the ID code of the specific part. And there is no gain for MX Stereo output with 5-bit volume control. Drive GPIO0 as low. The first three codes have been assigned by Microsoft for Plug and Play definitions.

D or later Change Version from 0. Correct dimension typing error in section Update section 6.
Ordering Information, page Add a note to, and change Susceptibility Voltage data in section 7. General Description Block Diagram Pin Assignments Pin Description Electrical Characteristics Analog Performance Characteristics Design Suggestions Application Circuits Mechanical Dimensions Ordering Information The ALC CODEC provides three pairs of stereo outputs with 5-Bit 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.
Pin Assignments 4. Pin Description 5. CMOS output, internal pulled low by a K resistor. The clock source is See section 7. Registers 6. Reading unimplemented registers will also return a 0. MX38 is the master volume control of surround output. Reading this register returns the ID code of the specific part. The written data is ignored. Each step on the left and right channels corresponds to a 1. Mono output is the same data sent on all output channels. Each step in bits corresponds to a 1.
Because software modem applications may not have a speaker, the CODEC can offer a speaker-out service. Each step in bit 6 corresponds to a magnification of 20dB increase in volume. Each step in bits selects a recording source for the right channel.
Each step in bits selects a recording source for the left channel. Bit 13 enables or disables 3D control. Bit 9 allows selection of mono output. Bit 8 controls the mic selector. Bit 7 enables loopback of the AD output to the DA input without involving the AC-Link, allowing for full system performance measurements.
The status will change regardless of interrupt enable I0. This bit reflects the cause of the first interrupt event generated. Software should read it after interrupt status I4 has been confirmed as interrupting. I2 will be zero when I4 is cleared. In ALC, this bit controls the interrupt of sense cycle. ALC supports 48KHz sample rate. If validity control is set MX3A. Sample Frequency in channel status It is combined with FC. Always read as 0. Write 1 to clear this status bit.
Bit 2 is used to select the clock source for the ALC Software must set this bit to disable Vrefout output before MX6A. Default 1: Enable, when MX7A. Internal MX This function should be implement by digital designer.
The first three codes have been assigned by Microsoft for Plug and Play definitions. The fourth code is a Realtek assigned code identifying the ALC Electrical Characteristics 7. Customer designing with a different AVDD should contact Realtek technical support for special testing support. Minimum 36 36 Typical Design Suggestions 9. NC: Not connected or pulled high. The ALC should use external The ALC will return any uninstalled bits or registers with 0 for read operations.
Reset all registers to its default value. Below is an example of differential CD input. Example of Differential CD Input 9. It is possible to design a system which will save op-amp circuitry and pass CD output directly to the speaker. Application Circuits The application circuit is for design reference only. To get the best compatibility in hardware design and software driver, any modifications of application circuits should be confirmed by Realtek. Ordering Information Table 1.
