SN65LV1023A analog and digital supply

Other Parts Discussed in Thread: SN65LV1023A, SN65LV1224B

Hi

 I am using SN65LV1023A/SN65LV1224 and facing some problem 

connection for SN65LV1023A

TCLK_R/F & DEN connected to 3.3v

TCLK connected to  48Mhz

connection for SN65LV1224B

RREFCLK connected to  48Mhz

RCLK_R/F & REN connected to 3.3v

after sync1 held high for 6T lock goes low and i am receiving data  successfully with latching on RCLK

Now my problem is that i want to transmit Din for only one time is their any way to do that

or is their any Dene pin to indicate the 10bit is  transmitted successfully??

    Hi Nishant,


    I am a little confused on what it is that you want to do. You want to send only ten bits of data and then stop the transmission?


    If so on the serializer you could pull the PWRDN pin, which is active low, low and place the outputs into a high impedance state. There is no function on the SN65LV1xxx devices that will report out that 10 bits of data were successfully transmitted. You could check this via the receiving the device and build a circuit with GPIO that will pull the PWRDN pin low on either IC?
