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 D3cold 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 VAUX support detection. VAUXP pin is driven high to indicate that ACPI is supported with D3cold 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.
