AWR1243: AWR1243P cascade

Bill973872

Part Number: AWR1243

Hello all,

I want to configure 4 AWR1243P(including Master) in HW trigger mode and provide the SYNC pulse from external processor to trigger the frame at all the devices.But I don't know the parameter of the signal "SYNC_IN". Can anybody provide the electrical parameters of this signal to me?Or,how can I get these parameters from a AWE1243BOOST EVM?

Thank you so much.

Best regards

Hi Bill,

The digital SYNC_IN and SYNC_OUT are powered by the VDDIO 1.8V/3.3V supply. These are LVCMOS buffers just like the I2C, SPI, UART...etc. The specs for those LVCMOS IO can be found int the AWR datasheets, under the recommended operating conditions table. Below I have excerpted the relevant spec.

Thank you,

-Randy
