Definitions
KTXN
78
I
Low-voltage DAA analog differential negative input
TXN
79
O
Codec negative analog output. The DC level is Vcm, and the full-scale ac output is 2.8V p-p±5%. The maximum loading
is 1k Ω, in parallel with 20 pF for modem applications. For audio applications with low-impedance load, the maximum
distortion-free (THD <–60-db) current is 10 mA rms.
TXP
80
O
Codec positive analog output. The DC level is Vcm, and the full-scale ac output is 2.8V p-p±5%. The maximum loading is
1k Ω, in parallel with 20 pF for modem applications. For audio applications with low-impedance load, the maximum
distortion-free (THD <–60-db) current is 10 mA rms.
VAUX
83
I
Power to device during implementation of the D3_cold state required by PCI Power Management Interface specification.
PF0
84
I
Pulled to VDD through a 4.7k Ω resistor.
PME#
85
O
Power management enable interrupt output to wake up the system.
VAUXP
86
I
V_AUX support detection. V_AUXP pin is driven high to indicate that ACPI is supported with D3_cold state. No support when
driven low.
RST#
87
I
Active-low ES2839 reset input.
INTA#
88
O
Interrupt request, active-low. This pin is the level triggered interrupt pin dedicated to servicing internal device interrupt
sources.
PCICLK
90
I
System bus clock input.
