Part Number: TUSB1046-DCI

HI team,

Could you help check the sink and source side circuit below? (DP only)

Sink side

     1. I2C_EN : GND

     2. SSEQ0/A0 : use 1k pull down to GND

     3. SSEQ1 : use 1k pull down to GND

     4. EQ0 : use 1k pull down to GND

     5. EQ1:  use 1k pull down to GND

     6. DPEQ0/A1 connection?

     7. DPEQ1 connection?

Source side

     1. I2C_EN : use 1k pull down to GND

     2. SSEQ0/A0 : use 1k pull down to GND

     3. SSEQ1 : use 1k pull down to GND

     4. EQ0 : use 1k pull down to GND

     5. EQ1 : use 1k pull down to GND

     6. DPEQ0/A1 connection?

     7. DPEQ1 connection?

Regards,

Roy

    Hi Roy,

    DPEQ selection would ultimately depend on the application PCB trace length. In the schematic customer should leave allowance for pull-up to 3.3V and pull-downs to GND for additional EQ options, see Table 1. 4-Level Control Pin Settings in datasheet. Tuning should be done to find the appropriate value but customer can leave pins floating to select EQ setting 10.
