ds90cr287 Debugging Summary

The ds90cr287 transmitter converts bits of LVCMOS/LVTTL data into four LVDS data streams.

Here is the pin chart for it:

Rxoutn corresponds to the TXINN,TXCLK in corresponds to the RXCLK out

Principle schematic:

Debugging Success Precautions:

①PLL VCC decoupling capacitance:

② Power Integrity: sufficient current supply

③ pin 32PWR dwn processing:

When the PWR Dwn is high and the device is enabled, the input clock must be present when the pin is high.

The clock first, after the PWR dwn for high can start normally, or all modules at the same time power can be started normally.
