...
200MHz CLK is enabled after power up.
I2C
Connect SI5338, LTM and FMC, SODIMM I2C and internal FAN Control to FPGA I2C Bus.
Si5338 configuration is not implemented.
FAN1
I2C Baseaddress: 0x74 (changeable with Firmware update). I2C with 8Bit Register Address with 8Bit Data. I2C CLK currently 20 MHz supported.
Write Access:
| Register Address | Name | Description |
|---|---|---|
| 0 | FAN CTRL | Enable FAN1 (Bit7) |
| 1 | FAN1 PWM | FAN1 PWM (0%-100%, Default 80%) |
Read Access:
| Register Address | Name | Description |
|---|---|---|
| 0 | FAN CTRL | FAN Control register |
| 1 | FAN1 RPS | FAN1 Revolutions per second |
Button
Button is debounced and controls PROG_B signal from FPGA.
...
- BUGFIX: PCIe Reset
- USER LED accessible
- I2C for SI5338, LTM, FMC, SODIMM
- Add FAN Control over I2C
