Page 5 of 8 CS1007 USB 2 Ch D. Amp Rev.A, 2006.02.07 Function Description Operation Clock Connect To operate CS1007, it requires an external 12MHz Crystal Oscillator thru XIN of pad 62. Figure 1 shows the recommend application circuit to connect a 12MHz Crystal Oscillator with CS1007. CS1007 XIN XOUT 10MW 12MHz 10pF 10pF Figure 1. CS1007 Use One 12MHz Crystal Application Circuit Embedded PLL CS1007 is embedded a set of PLL to generate the operation clock for internal use. In order to operate PLL normally, it is required to connect FILT of pad 54 with a set of RC circuit to ground. Figure 2 illustrates the recommend application circuit of connect FILT with RC circuit. 3.3V 10uF 330 W VDD (Pad52~53) FILT (Pad 54) VSS (Pad 55~56) 1uF Figure 2. CS1007 FILT (Pad 54) External RC Circuit Reset RESET_B pad of CS1007 is the Global Reset for all internal circuit. Table 1 is the setup of RESET_B. When reset CS1007, RESET_B must be set to Low, and remain Low at least 1ms.Then return to High to complete the process of Reset. Therefore, it is recommended to discharge RC in the application circuit and design a simple Power On Reset to stable CS1007 after power on. _________________________________________________________________________________________________ ChipSale Technology, Inc., reserves the right to change product or specifications without notice.

RESET_B Configuration RESET_B CS1007 Status 0 Reset 1 Normal Operation USB Active Indication LED CS1007 provides USB_ACT_LED of pad 10 to connect a LED to indicate the current status of CS1007 receiving USB data. Table 2 lists the configuration of the output of USB_ACT_LED. There are three conditions as stated below. 1. When USB_ACT_LED outputs Low, CS1007 has not yet been completely configured by USB Host. Or USB Host is under Suspend Mode and cannot configure CS1007. 2. When USB_ACT_LED outputs High, CS1007 has been completely configured by USB Host and waiting for the transmission of Audio Data. 3. When Audio Data is transmitted to CS1007, USB_ACT_LED will output the 1 second period pulse. Table 2. USB_ACT_LED Configuration USB_ACT_LED CS1007 Receive USB Data Status 0 USB Configure Non Ready or USB Host In Suspend Mode 1 USB Configure Ready 1 Sec Period Pulse Receive Audio Data From USB Single 5V Power Regulation CS1007 can use the power directly from USB Port of PC. The power supply from USB is 5.0V 500mA. Figure 3 illustrates how CS1007 built-in Voltage Regulator connects with USB power. CS1007 is required only serial connecting two 1N4004 to VREG_I (Pad 16) and the 5V power supply from USB and output 3.3V voltage for digital circuits from VREG_O (Pad 15). And also connect VREG_O and VDD (Pad 48-49, 52-53, 64-66), link one 1.5K resist between DP (Pad 1) and VREG_O. _________________________________________________________________________________________________ ChipSale Technology, Inc., reserves the right to change product or specifications without notice.
