Use a power supply VDD 5 voltage that corresponds to the switching levels of clock input(s) (i.e. 1.8V, 2.5V, or 3.3V). Device Control Mode Select OPEN = Device Configured via pins (Pin Mode) HIGH = Device Configured via I2C MODE 30 LOW = Device Configured via SPI Note: For information on control via the serial interface (I2C/ SPI), see DEVICE CONTROL USING THE HOST INTERFACE section. Input Divider Pin Control DIVIDE 1 (HIGH = /4, LOW = /2, OPEN = /1) Device Output Enable OE 32 HIGH = Enable, LOW = Disable Output Edge Rate Control ERC 31 HIGH = Medium, LOW = Slow, OPEN = Fast INSEL 2 Input Multiplexer Control ITTP 8 Input Type Select (HIGH = HCSL, LOW = LVDS, OPEN = LVCMOS) IN1P 3 Universal Input 1 – Positive Terminal IN1N 4 Universal Input 1 – Negative Terminal, Ground if using IN1 in single-ended mode IN2P 6 Universal Input 2 – Positive Terminal IN2N 7 Universal Input 2 – Negative Terminal, Ground if using IN2 in single-ended mode OTTP 19 Output Type Select (HIGH = HCSL, LOW = LVDS, OPEN = LVCMOS) OUT1P 9 Output 1 – Positive Terminal OUT1N 10 Output 1 – Negative Terminal VDDO1 11 Output Power Supply – OUT1, OUT2 OUT2P 12 Output 2 – Positive Terminal (1) This pin list applies to operation of the device in pin mode. In host mode, certain pins take on an alternate function as outlined in Table 9. Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Link(s) :CDCUN1208LP |
