The Audio Data Format supports 16-bit, 2-channel, and 48kHz, 44.1kHz, 32kHz, 8kHz PCM. It has three interfaces. Interface 1 supports four sampling frequencies. The sampling rate is changed by FS_SEL0 and FS_SEL1. For Interface 2, this device transmits data at a rate that is locked to frame timing. When user uses the recording format (ex. 8kHz) to record speech other than 48kHz stereo format, the application software will transform 48kHz data to 8kHz data. Interface 3 is HID pipe which is used to read user data. The EKA8566A defines a PSTN + Skype protocol to communicate with an external MCU. The device can use the protocol to by pass USB vendor data to external MCU or read data from external MCU to USB host. 8 Absolute Maximum Rating Symbol Temperature under bias Storage temperature Input voltage Output voltage Min 0 -65 -0.5 -0.5 Max 70 150 6.0 6.0 Unit C C V V 6* Product Specification (V0.1) 10.23.2006 (This specification is subject to change without further notice) EKA8566A USB Audio Controller 9 Electrical Characteristic 9.1 DC Electrical Characteristic Ta = 0C~70C, VBus = 5V, DGND = 0V Symbol IIL VIH VIL VIHX VILX VOH1 VOH2 VOL1 VOL2 VOL3 IPH IPL ISB1 ISB2 ICC Parameter Input Leakage Current Input High Voltage Input Low Voltage Clock Input High Voltage Clock Input Low Voltage Output High Voltage (Port 5, Port 6) Output High Voltage 2 (I S Interface Pin) Output Low Voltage (Port 5, Port 6) (P5 : Normal Mode) Output Low Voltage (P5 : LED driver Mode) Output Low Voltage 2 (I S Interface Pin) Pull-high Current (Port 5 and Sel_Vref pin) Pull-low Current (Test pin) Power Down Current Power Down Current Operating Supply Current OSCI OSCI Condition VIN = VBus, DGND - - Min - 2.0 Typ - - - - - - - - 1.3 - -125 125 - - - Max 1 - 0.8 - 1.0 - - 0.4 +10% 0.4 +20% +20% 50 100 10 Unit A V V V V V V V V V A A A A mA 2.5 - 2.4 2.4 - -10% - IOH = -10.0mA IOH = -6.67mA IOL = 10.0mA IOL = 10.0mA VBus = 5 V IOL = 6.67mA Pull-high active, input pin at DGND -20% (PH resistor = 25K) Test pin at VBus (PL resistor = 25K) All input and I/O pin at VBus, output pin floating, WDT disabled All input and I/O pin at VBus, output pin floating, WDT enabled Fosc= 6.0 MHz , output pin floating -20% - - - Product Specification (V0.1) 10.23.2006 (This specification is subject to change without further notice) *7 EKA8566A USB Audio Controller 9.2 Analog Electrical Characteristic Parameter ADC ADC Resolution ADC Sampling Frequency Internal High Reference Voltage for ADC Internal Low Reference Voltage for ADC Pre-Amplifier Spec.

When EKA8566A sends command/data to CID, CRS is used to indicate if CID receives the command/data. CRS is asserted after CLK is asserted, CRS is de-asserted after CLK is de-asserted. If CRS is not asserted, then indicate that CID does not receive command/data. When CID requests to send command/data to EKA8566A, CRS will be asserted. CLK is asserted after CRS is asserted, CLK is de-asserted after CRS is de-asserted. If CLK is not asserted, then indicate that the EKA8566A does not receive command/data.
