Texas Instruments · USB Converters · VQFN-24-EP(4x4)

TUSB1002AIRGER from Texas Instruments, in a VQFN-24-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in 3.3V (±10%) power supply.
2 CH1_EQ1 input Configuration pin (4-level input) to control Rx EQ level for RX1P/N; internal pullup 45kΩ, pulldown 95kΩ; state sampled after rising edge of EN.
3 CH1_EQ2 input Configuration pin (4-level input) to control Rx EQ level for RX1P/N; internal pullup 45kΩ, pulldown 95kΩ; state sampled after rising edge of EN.
4 CFG1 input Configuration pin (4-level input) to select VOD linearity range and DC gain for both channels; internal pullup 45kΩ, pulldown 95kΩ; state sampled after rising edge of EN.
5 EN input Enable pin (2-level input); places device into shutdown when asserted low, normal operation when asserted high; internal pullup 400kΩ.
6 GND power_in Ground.
7 MODE input Configuration pin (4-level input) for selecting different modes of operation; internal pullup 45kΩ, pulldown 95kΩ; state sampled after rising edge of EN.
8 RX1N input Differential input for SuperSpeed and SuperSpeedPlus negative signals for Channel 1; 90Ω differential impedance.
9 RX1P input Differential input for SuperSpeed and SuperSpeedPlus positive signals for Channel 1; 90Ω differential impedance.
10 GND power_in Ground.
11 TX2N output Differential output for SuperSpeed and SuperSpeedPlus negative signals for Channel 2; 90Ω differential impedance.
12 TX2P output Differential output for SuperSpeed and SuperSpeedPlus positive signals for Channel 2; 90Ω differential impedance.
13 VCC power_in 3.3V (±10%) power supply.
14 DCBOOST# input DC Boost control pin (2-level input); when asserted low increases DC Gain level by +1dB unless already at +2dB; internal pullup 400kΩ.
15 CFG2 input Configuration pin (4-level input) to set VOD linearity range and DC gain for both channels; internal pullup 45kΩ, pulldown 95kΩ; state sampled after rising edge of EN.
16 CH2_EQ1 input Configuration pin (4-level input) to control Rx EQ level for RX2P/N; internal pullup 45kΩ, pulldown 95kΩ; state sampled after rising edge of EN.
17 CH2_EQ2 input Configuration pin (4-level input) to control Rx EQ level for RX2P/N; internal pullup 45kΩ, pulldown 95kΩ; state sampled after rising edge of EN.
18 GND power_in Ground.
19 RX2P input Differential input for SuperSpeed and SuperSpeedPlus positive signals for Channel 2; 90Ω differential impedance.
20 RX2N input Differential input for SuperSpeed and SuperSpeedPlus negative signals for Channel 2; 90Ω differential impedance.
21 GND power_in Ground.
22 TX1P output Differential output for SuperSpeed and SuperSpeedPlus positive signals for Channel 1; 90Ω differential impedance.
23 TX1N output Differential output for SuperSpeed and SuperSpeedPlus negative signals for Channel 1; 90Ω differential impedance.
24 RSVD1 output Reserved pin; driven low by TUSB1002A under normal operation; recommend leaving unconnected on PCB.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
