Part Number: SN74CBTLV3257
Hi,
We are using SN74CBTLV3257PWR in one of our application. The enable pin and switch select pin is both pulled to ground via 10K resistor, which makes the data flow between port A and Port B1.
We have used all the four channels(specifically we are using SPI signal CLK, CS, MISO and MOSI). The speed of the SPI signal is 80MHz. We are using it in a camera application where the data flow is between FPGA and SFLASH via SN74CBTLV3257PWR. We are unable to get exact output.
When we connect the SPI lines directly between FPGA and SFLASH the operation is fine and we are able to get the output. Not sure where we are missing when using SN74CBTLV3257PWR part.
Any reply regarding this is much appreciated. Thank You.
