Texas Instruments · Signal Buffers, Repeaters, Splitters · QFN-24-EP(4x4)

TUSB522PRGER from Texas Instruments, in a QFN-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 Positive power supply, 3.3 V nominal (3.0 V min, 3.6 V max).
2 EQ1 input Channel 1 receiver equalizer gain select. 3-state CMOS input with integrated pull-up/pull-down. Low=3 dB, Mid=6 dB, High=9 dB.
3 DE2 input Channel 2 output de-emphasis select. 3-state CMOS input with integrated pull-up/pull-down. Low=0 dB, Mid=-3.5 dB, High=-6.2 dB. Forced Low when OS=Low.
4 OS2 input Channel 2 output swing (differential voltage amplitude) select. 2-state CMOS input with integrated pull-down. Low=0.9 mV, High=1.1 mV.
5 EN_RXD input Enable input. Device active when EN_RXD=High. Internal 660 kΩ pull-down; drive actively or install ~4.7 kΩ pull-up for normal operation. Resets state machine when Low.
6 NC unconnected No connection. May be tied to any voltage including GND.
7 NC unconnected No connection. May be tied to any voltage including GND.
8 RX1N input Channel 1 differential receiver input, negative (5 Gbps USB 3.1 GEN1).
9 RX1P input Channel 1 differential receiver input, positive (5 Gbps USB 3.1 GEN1).
10 GND power_in Ground. May be connected to GND or left unconnected (thermal PAD is the primary GND connection).
11 TX2N output Channel 2 differential transmitter output, negative (5 Gbps USB 3.1 GEN1).
12 TX2P output Channel 2 differential transmitter output, positive (5 Gbps USB 3.1 GEN1).
13 VCC power_in Positive power supply, 3.3 V nominal (3.0 V min, 3.6 V max).
14 RSV input Reserved. Can be left as no-connect.
15 OS1 input Channel 1 output swing (differential voltage amplitude) select. 2-state CMOS input with integrated pull-down. Low=0.9 mV, High=1.1 mV.
16 DE1 input Channel 1 output de-emphasis select. 3-state CMOS input with integrated pull-up/pull-down. Low=0 dB, Mid=-3.5 dB, High=-6.2 dB. Forced Low when OS=Low.
17 EQ2 input Channel 2 receiver equalizer gain select. 3-state CMOS input with integrated pull-up/pull-down. Low=3 dB, Mid=6 dB, High=9 dB.
18 NC unconnected No connection. May be tied to any voltage including GND.
19 RX2P input Channel 2 differential receiver input, positive (5 Gbps USB 3.1 GEN1).
20 RX2N input Channel 2 differential receiver input, negative (5 Gbps USB 3.1 GEN1).
21 GND power_in Ground. May be connected to GND or left unconnected (thermal PAD is the primary GND connection).
22 TX1P output Channel 1 differential transmitter output, positive (5 Gbps USB 3.1 GEN1).
23 TX1N output Channel 1 differential transmitter output, negative (5 Gbps USB 3.1 GEN1).
24 NC unconnected No connection. May be tied to any voltage including GND.
PAD GND power_in Exposed thermal pad on package bottom. Must be soldered to the PCB ground plane for electrical and thermal performance.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (24 pp, sha256 057e12f6ff5c79f5, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
