Hello Sevender,
The SSCG modulation frequency is the rate at which the clock frequency is varied. If you measure the jitter of the oscillator in the BW of 200kHz - 10MHz, then the SSCG modulation frequency should not appear in your measurement.
It…
Hello Puneeth,
The 954 deserializer MUST have a 25MHz clock fed into its XIN/REFCLK pin. Below is an excerpt from the DS90UB954 datasheet on ti.com.
I don't recognize the Figure that you shared, but the latest version of the dataasheet states that…
Part Number: DS90UB954-Q1 Hello Team,
I got a question from customer about unused XIN/REFCLK pin of 954.
They will use non-synchronous mode so they don't input any Xrystal/REFCLK into 954. If so, how do they deal the XIN/REFCLK pin? (NC or Tied to…
Part Number: DS90UB954-Q1 Dear Team,
Customer are designing with our deseri 954, and want to know XIN spec.
I have found an E2E post which recommend follow datasheet for XIN design.
Did we need to follow REFCLK spec(datasheet 7.4.4) even when…
Part Number: DS90UB954-Q1 Tool/software: I have designer deserializer using DS90UB954-Q1 and Serializer using DS90UB953 But my Serializer is not get detected all the time at serializer some time it detects some time it won't detect If my serializer is…
Part Number: DS90UB954-Q1 Hello everyone,
When using deserializer UB954 is it mandatory to connect an external clock to UB954's XIN/REFCLK pin (e.g. a crystal source), in order to achieve successful connection with ,lets say, UB953 serializer via…
Part Number: DS90UB954-Q1 Dears,
I use deserializer DS90UB954, have n o image output after 4 to 5 minutes of work, the I2C communication is normal, could you help to review sch, thanks!
