Port Characteristics
Universal (Bi-directional) jacks are supported on ports A,C, and F. Ports A and B are designed to
drive 32 ohm (nominal) headphones or a 10K (nominal) load. Line Level outputs are intended to
drive an external 10K load (nominal) and an on board shunt resistor of 20-47K (nominal). However,
applications may support load impedances of 5K ohms and above. Input ports are 50K (nominal) at
the pin.
DAC full scale outputs and intended full scale input levels are 1V rms at 5V. Line output ports and
Headphone output ports on the 92HD99 codec may be configured for +3dBV full scale output levels
by using a vendor specific verb.
Output ports are always on to prevent pops/clicks associated with charging and discharging output
coupling capacitors. This maintains proper bias on output coupling caps even in power state D3 as
long as AVDD is available. Unused ports should be left unconnected. When updating existing
