Part Number: CDCI6214

Tool/software: Linux

Hi

what is the programming procedure for the CDCI6214?

when i follow the section 9.5.1 as per the data sheet(SNAS734 – JULY 2017), not able to observe any clock at he output Channels.

the register are configured with the default values as specified in Table 14 (even tried with EEPROM 0) of the datasheet.

A reference clock to the PLL is fed to pins 1 (XIN) and 2 (XOUT) 25MHz. Pin OE and RST are set to HIGH.

please suggest what are the registers need to  check for enabling the output frequency at CDCI6214.

thanks

    HI Lane

    Thanks for the reply.

    I am setting the registers  as per data sheet default values. I am expecting some default clock at output CH1/2/3/4.

    Please help us to check which register setting  are we missing to ENABLE the OUTPUT.

    Address -16 bit, followed by data - 16 bit

    Following is the format  feeding to the CDCI through I2C.
