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 | 3.3 V (±10%) supply. Bypass to ground close to the pin. |+| 2 | CH1_EQ1 | input | 4-level configuration input. Together with CH1_EQ2 selects one of 16 Rx EQ settings for the RX1P/N channel. Sampled after rising edge of EN. Internal PU ≈45 kΩ / PD ≈95 kΩ. |+| 3 | CH1_EQ2 | input | 4-level configuration input. Together with CH1_EQ1 selects one of 16 Rx EQ settings for the RX1P/N channel. Sampled after rising edge of EN. Internal PU ≈45 kΩ / PD ≈95 kΩ. |+| 4 | CFG1 | input | 4-level configuration input. With CFG2 selects VOD linearity range and DC gain for both channels. Sampled after rising edge of EN. Internal PU ≈45 kΩ / PD ≈95 kΩ. |+| 5 | EN | input | 2-level enable. Asserted high for normal operation; low places TUSB1002A in shutdown with high-Z receiver terminations and disabled TX/RX channels. Internal PU ≈400 kΩ. |+| 6 | GND | power_in | Ground return. |+| 7 | MODE | input | 4-level mode select sampled after rising edge of EN. 0 = Basic Redriver, R = PCIe/Test mode (TI internal), F = USB 3.2 x1 dual-channel operation, 1 = USB 3.2 x1 single-channel operation. Internal PU ≈45 kΩ / PD ≈95 kΩ. |+| 8 | RX1N | input | 90 Ω differential input, negative signal for Channel 1 SuperSpeed/SuperSpeedPlus receiver. |+| 9 | RX1P | input | 90 Ω differential input, positive signal for Channel 1 SuperSpeed/SuperSpeedPlus receiver. |+| 10 | GND | power_in | Ground return. |+| 11 | TX2N | output | 90 Ω differential output, negative signal for Channel 2 SuperSpeed/SuperSpeedPlus transmitter. |+| 12 | TX2P | output | 90 Ω differential output, positive signal for Channel 2 SuperSpeed/SuperSpeedPlus transmitter. |+| 13 | VCC | power_in | 3.3 V (±10%) supply. Bypass to ground close to the pin. |+| 14 | DCBOOST# | input | 2-level DC gain boost control. Asserting low increases the DC gain (defined by device table) by +1 dB unless already at +2 dB. Internal PU ≈400 kΩ; leave unconnected if not used. |+| 15 | CFG2 | input | 4-level configuration input. With CFG1 sets VOD linearity range and DC gain for both channels. Sampled after rising edge of EN. Internal PU ≈45 kΩ / PD ≈95 kΩ. |+| 16 | CH2_EQ1 | input | 4-level configuration input. Together with CH2_EQ2 selects one of 16 Rx EQ settings for the RX2P/N channel. Sampled after rising edge of EN. Internal PU ≈45 kΩ / PD ≈95 kΩ. |+| 17 | CH2_EQ2 | input | 4-level configuration input. Together with CH2_EQ1 selects one of 16 Rx EQ settings for the RX2P/N channel. Sampled after rising edge of EN. Internal PU ≈45 kΩ / PD ≈95 kΩ. |+| 18 | GND | power_in | Ground return. |+| 19 | RX2P | input | 90 Ω differential input, positive signal for Channel 2 SuperSpeed/SuperSpeedPlus receiver. |+| 20 | RX2N | input | 90 Ω differential input, negative signal for Channel 2 SuperSpeed/SuperSpeedPlus receiver. |+| 21 | GND | power_in | Ground return. |+| 22 | TX1P | output | 90 Ω differential output, positive signal for Channel 1 SuperSpeed/SuperSpeedPlus transmitter. |+| 23 | TX1N | output | 90 Ω differential output, negative signal for Channel 1 SuperSpeed/SuperSpeedPlus transmitter. |+| 24 | RSVD1 | output | Reserved. Driven low by TUSB1002A during normal operation. TI recommends leaving this pin unconnected on the PCB. |+| 25 | Thermal Pad | power_in | Exposed thermal pad. Connect to a solid ground plane for electrical and thermal performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-24(4x4) |+| Category | Interface |+| Pins | 25 |++## Ordering variants++Same part, different packaging or reel option.++- `TUSB1002ARGER`+- `TUSB1002ARGERRGET`++## CAD (KiCad official)++- Symbol: `TUSB1002ARGER`+- Footprint: `Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.7x2.7mm`+- 3D model: VQFN-24(4x4) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/tusb1002arger-datasheet.pdf) (36 pp, sha256 `48ae8089253807e4`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
