SLLSFO9A May 2024 – September 2024 TUSB564-Q1
PRODUCTION DATA
The TUSB564-Q1 has (I2C_EN, EQ[1:0], DPEQ[1:0], and SSEQ[1:0]) 4-level inputs pins that are used to control the equalization gain and place TUSB564-Q1 into different modes of operation. These 4-level inputs use a resistor divider to help set the four valid levels and provide a wider range of control settings. There is an internal 35kΩ pullup and a 95kΩ pulldown. These resistors, together with the external resistor connection combine to achieve the desired voltage level.
LEVEL | SETTINGS |
---|---|
0 | Tie 1kΩ 5% to GND |
R | Tie 20kΩ 5% to GND |
F | Float (leave pin open) |
1 | Tie 1kΩ 5% to VCC |
All 4-level inputs are latched after the rising edge of internal reset. After tcfg_hd, the internal pullup and pulldown resistors are isolated to save power.
