TUSB1002ARGER from Texas Instruments, in a VQFN-24(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	3.3 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.
