9 / 28 page Connection Diagram 20123502 Top View Order Number LM4549BVH See NS Package Number VBH48A Pin Descriptions ANALOG I/O Name Pin I / O Functional Description PC_BEEP 12 I Mono Input This line level (1 Vrms nominal) mono input is mixed equally into both channels of the Stereo Mix signal at MIX2 under the control of the PC_Beep Volume control register, 0Ah. The PC_BEEP level can be muted or adjusted from 0 dB to -45 dB in 3 dB steps. The Stereo Mix signal feeds both the Line Out and Line Level Out analog outputs and is also selectable at the Record Select Mux. During Initialization or Cold Reset, (reset pin held active low), PC_BEEP is switched directly to both channels of the Line Out stereo output, bypassing all volume controls. This allows signals such as PC power-on self-test tones to be heard through the PC’s audio system before the codec registers are configured. PHONE 13 I Mono Input This line level (1 Vrms nominal) mono input is selectable at the Record Select Mux for conversion by either channel of the stereo ADC. It can also be mixed equally into both channels of the Stereo Mix signal at MIX2 under the control of the Phone Volume register, 0Ch. The PHONE level can be muted or adjusted from +12 dB to -34.5 dB in 1.5 dB steps. The Stereo Mix signal feeds both the Line Out and Line Level Out analog stereo outputs and is also selectable at the Record Select Mux. www.national.com 9 |
