maxim integrated 9 max9273 coax evaluation kit evaluates: max9272/max9273 with fakra coaxial cable www.maximintegrated.com detailed description of hardware the max9273 coax ev kit provides a proven layout for the max9273 gmsl serializer. on-board level translators and easy-to-use usb-pc connection are included on the ev kit. the max9272 coax ev kit board layout is divided into four principal sections: 1) power-supply circuitry. on-board ldo regulator u2 powers the avdd, dvdd, and iovdd supplies from vin. 2) max9272 and its support components. 3) microcontrollers (u10Cu14). 4) i 2 c slave device (u15). the microcontroller and i 2 c slave device sections are identical on the max9271Cmax9273 coax ev kits. microcontroller-supplied i 2 c interface the microcontroller-supplied i 2 c interface (through u12 and u14) is intended to operate while both serializer and deserialzer boards are powered on and locked. if the microcontroller-supplied i 2 c interface is to be used in any other case, one of the following should be done: use an iovdd of 2.2v or greater with the i 2 c interface, or use a 100kbps i 2 c data rate. user-supplied interface to use the max9273 coax ev kit with a user-supplied interface, first cut the pcb traces at jumpers ju141 and ju142. next, apply your own tx/scl signal at the u1 side of ju141 and rx/sda at the u1 side of ju142. refer to the max9273 and max9272 ic data sheets for details about uart protocol for base mode, write data format, read data format, selecting base mode or bypass mode, and selecting a uart or i 2 c slave device. user-supplied power supply the max9273 and max9272 coax ev kits are powered completely from the usb port by default. jumper ju_usb+5v connects the 5v usb supply and the vin power supply. to provide different power supplies to avdd, dvdd, and iovdd, remove the shunts from jumpers ju21Cju23 and apply external user-supplied power at the avdd, dvdd, and iovdd oval pcb pads, respectively. detailed description of firmware the ds89c450 microcontroller (u12) runs custom firmware that ensures that no breaks occur within register read/write commands. the firmware records 9-bit even- parity data received from the usb interface while rts is set, and plays back the 9-bit data with 1.5 stop bits timing when rts is cleared. data received from the max9273 is immediately relayed to the usb. the firmware also supports a small set of commands, available when rts is clear. since all register read/ write requests are sent with rts set, there is no conflict between register data and firmware commands. these firmware commands are issued automatically by the max9273 coax ev kit software gui. the following infor - mation is provided for reference only: firmware command ? prints the firmware version banner message and brief command list. firmware command b changes the baud rate by changing the internal th1 baud-rate divisor. refer to the firmware help command ? for details. pressing sw122 resets the usb baud rate to 921600 baud. the software gui automatically sends the baud-rate change command. firmware command t supports waking up the max9273 from the max9272 side of the link. command t performs a dummy read, followed by a delay on the order of 1ms to 8ms, and finally writes a register value. for example, send t810504800483 to read from device address 0x81 register 0x05, delay 4ms, then write to device address 0x80 register 0x04 data 0x83. this is the max9273 wake-up sequence for the default device addresses. firmware commands r and w read and write device registers. the 8-bit device address, register address, length, and data are sent in hexadecimal. on success, the return code is + followed by the read data. on failure, the return code is -. some commands are used only during firmware devel - opment. firmware command s simulates a dummy device using on-chip memory instead of device reg - isters, used during firmware development. firmware command ~ prints a diagnostic trace dump used during firmware development. firmware commands 1 and 2 perform hdcp link authentication check operations, used during firmware development. in normal operation, these operations not used for the max9273. downloaded from: http:///
