Other Parts Discussed in Thread: , TUSB522P,
Hi, I am going to use TUSB1002 for my usb 3.2 device.
I have 4 questions for using this. Please help me.
-----------------------------------------------------------
Tusb1002 has too many options for setting.
But there is no pcb area for put pin header for options like TUSB1002EVM.(EQ1, EQ2, CF1, CF2, ..etc)
I am using this TUSB1002 first time, so I have no idea about how these settings wil effect USB Signals.
-----------------------------------------------------------------------------------------------------------------
1. What do you think about make all the pins for floating and put NC resistor for later tuning options?
Are making Floating these pins are kind of default mode?
-----------------------------------------------------------
2. I have another question about mode pin.
Mode 0 = Basic Redriver mode
Mode F = USB 3.2 Dual channel operation.
Could you tell me what is different between Basic Redriver mode and Dual channel operation?
---------------------------------------------
3. I have used TSUB522P before.
When I used this, No accoupling capacitors are placed on the RX2P and RX2N pins
because it is assumed the device downstream of the TUSB522P will have ac-coupling capacitors on its transmitter as defined by the USB 3.1 specification.
But In the datasheet TUSB1002, there says like below.
Is this mean I don't have to put ac coupling capacitor?
Or If I put 330nF and 220k Resistors as options, how does it will effect?
---------------------------------------------------
4. If I use TUSB522P for USB3.2 Devices, won't this work properly?
5. Can I tie EN pin to VCC?
Thanks.
