CDCM6208V1EVM: Are there Linux spi drivers cdcm6208?

Hi Patrick,

Yes your frequency can be implemented. There's no Linux driver for the EVM, but you can flywire the SPI lines.

Looking for a Linux driver to forward to software developer for use with my system using this clock generator.

Hi Patrick,

We don't have Linux SPI drivers.

Typical development flow for these products is:

1. Configure the desired register settings using TICS Pro software (Windows-based)
2. Export the register settings from TICS Pro as hexadecimal values in a text file. Text file is printed in register programming order.
3. Load the hex values to memory somewhere in your host processor, and write to the device using the SPI peripheral

Historically, we have not provided Linux drivers for our devices, as the use cases have typically been loading a static configuration file and maybe reading a handful of registers or I/O levels to decode status information. However, if this is something that seriously impedes development with our devices, we can look into providing these drivers.

If you don't mind me asking, what do you (or your software developer) require or expect from the device drivers? For example:

• Loading initialization sequences?
• Changing PLL parameters, input buffer properties, or output divider and buffer properties?
• Reading status registers or I/O state?

Regards,

I have run the EVM software to get a feel for this part.

Does not seem like I can get this part to achieve my goals:with Input 160 MHz

Y4 / Y5 = 160 MHz pass thru

Y0 - Y3 = 100 MHz

Y6 / Y7 = 80 MHz / 100 MHz switchable.<<< This is where software says not possible. Need for sampling mode change for TI AFE5832ZBV

If you can get this to work, send me a file to load.

Hi Derek,

Is it possible to also gate Y0-Y3 100 MHz outputs with an OE PIN?
