Part Number: TUSB564 Hi Team,
1. We use I2C control for adjusting DPEQ. How could we know what is the DPEQ level setting by register? I only see DPEQ table for GPIO mode in datasheet.
2. Customer found TUSB564 cannot symbol lock when they did RX test…
Part Number: TUSB564
Mainly failure symbol below stations:
1, cannot pass USB type-c hot plug and detect .
2.we already confirm failed symbol follow material
Issue. We have follow below analysis:
Swap a new U8 can pass , all the symbol follow material…
Hi Jason,
You need to follow the below writes to the I2C registers. Table 7. TUSB564 Receiver Equalization GPIO Control shows the EQ settings which are the same for I2C mode.
Set register 0x0A bit 4 = "1"
USB EQ: Set registers 0x20 and 0x2…
Part Number: TUSB564 Other Parts Discussed in Thread: TUSB1064 We use TUSB564(TUSB564IRNQT) as DP sink device re-driver. It have a performance issue. The output frame can not higher than 40frame @4K. Our schematic is the picture "schematic.jpg".…
Hello Chris,
I am grateful for your tremendous support.
We would like to control the TUSB1046(source) with I2C from the TPS65987, not the TUSB564(sink).
While I was searching E2E for a way to control the TUSB1046 via I2C, I found a thread introducing…
Part Number: TUSB564 Other Parts Discussed in Thread: TPS65987 hi Sir,
my customer application is DP UFP device(no usb3) with battery. when PC is in sleep mode, TUSB564 still works with full power. there is AUX snoop feature for power saving. due to the…
Part Number: TUSB564 Hi Team,
Customer would like to design TUSB564 on monitor application.
Would you please help review and provide comment on the TUSB564 schematic?

Hi James,
I believe you have a typo, 300mA * 3.3V = 990 mW. The 300 mA recommendation is to allow margin for additional pull-up resistors that may be used in the circuit. I expect TUSB564 to consume ~242mA (max) at its greatest power consumption level…
Part Number: TUSB564 Hi,
We would configure TUSB564 from PD controller IC using I2C mode, and have some questions as below.
Should we write EQ_OVERRIDE bit to '1' before or after we configure EQ setting in 0x10/0x11/0x20/0x21? Or it doesn't matter…

I'm working with a custom PCB design built around the TUSB564. The USB (both 2.0 and SuperSpeed) work exactly as expected, but the DisplayPort sink is never…
