3 / 29 page DS241PP5 3 CS4610/11 CrystalClear™ SoundFusion™ PCI Audio Accelerator AC CHARACTERISTICS (PCI SIGNAL PINS ONLY) (T A = 70° C; PCIVDD = CVDD = CRYVDD = 3.3 V; VDD5REF = 5 V; PCIGND = CGND = CRYGND = 0 V; Logic 0 = 0 V, Logic 1 = 3.3 V; Reference levels = 1.4 V; unless otherwise noted; (Note 4)) Notes: 4. Specifications guaranteed by characterization and not production testing. 5. Refer to V/I curves in Figure 1. Specification does not apply to CLK and RST# signals. Switching Current High specification does not apply to SERR# and INTA# which are open drain outputs. 6. Cumulative edge rate across specified range. Rise slew rates do not apply to open drain outputs. 7. Equation A: IOH = 11.9 * (Vout - 5.25) * (Vout + 2.45) for 3.3 V > Vout > 3.1 V 8. Equation B: IOL = 78.5 * Vout * (4.4 - Vout) for 0 V < Vout < 0.71 V Parameter Symbol Min Max Unit Switching Current High (Note 5) 0 < Vout < 1.4 1.4 < Vout < 2.4 3.1 < Vout < 3.3 IOH -44 - - - Note 7 mA mA Switching Current Low (Note 5) Vout > 2.2 2.2 > Vout > 0.55 0.71 > Vout > 0 IOL 95 Vout/0.023 - - - Note 8 mA mA Low Clamp Current -5 < Vin < -1 ICL -mA Output rise slew rate 0.4 V - 2.4 V load (Note 6) slewr 1 5 V/ns Output fall slew rate 2.4 V - 0.4 V load (Note 6) slewf 1 5 V/ns 44 – Vout 1.4 – 0.024 --------------------------- + 25 – Vin 1 + 0.015 ------------------- + Pull Up Pull Down Equation B: Equation A: 3.3 3.3 2.2 0.55 2.4 voltage voltage 1.4 DC drive point DC drive point AC drive point I = 11.9*(Vout-5.25)*(Vout+2.45) for 3.3V > Vout > 3.1V OH I = 78.5*Vout*(4.4-Vout) for 0V < Vout < 0.71V OL AC drive point test point test point -2 3, 6 95 380 -44 Current (mA) Current (mA) -176 Figure 1.
