ORDERING INFORMATION
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
, 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
,
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

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
