Other Parts Discussed in Thread: TUSB9261
Hello TI,
Would you please tell me about the internal oscillation circuit of TUSB9261-Q1?
Background:
This is a question from my customer. They expect prompt answers.
Among the devices of other manufacturers they use,
Some devices increase the gain of the internal oscillator circuit when the reset pin input is low and lower the gain when the reset pin input is High.
They will need to specify the measurement conditions when asking the crystal oscillator manufacturer to confirm matching of the oscillation,
so they want to check if TUSB9261-Q1 is doing similar switching.
They have a 20 MHz crystal externally attached to TUSB9261-Q1.
Questions:
(1)Is there a function to change the margin of the oscillation circuit depending on the state of the device?
(2)Does the oscillation gain become higher at power-on than during normal operation?
(2)Is the oscillation gain switched depending on the frequency band?
Best regards,Orobianco
