DP83TG720SWRHATQ1 from Texas Instruments, in a VQFN-36(6x6). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 MDC input Management data clock: synchronous clock for MDIO serial management input and output data.
2 INT_N output Active-low open-drain interrupt output with a weak internal pull-up; can be configured active-high via register 0x0011.
3 RESET_N input Active-low reset input with internal pull-up; hold low at least 10 µs to force reset, and strap pins are resampled on deassertion.
4 XO output Reference clock output used only with a crystal; leave floating when a CMOS oscillator drives XI.
5 XI input Reference clock input for a 25 MHz ±100 ppm crystal or CMOS oscillator (oscillator on XI only with XO floating).
6 LED_1/GPIO_1 bidirectional LED_1 shows link status, blinking on TX/RX activity; also the AUTO (autonomous/managed) strap pin with internal pull-down.
7 VSLEEP power_in 3.3 V sleep supply (2.97 to 3.63 V); connect to VDDA3P3 if the sleep function is not used.
8 WAKE input Active-high wake pulse input in the VSLEEP domain with internal pull-down that wakes the PHY from sleep; may be tied to VSLEEP if unused.
9 VDD1P0 power_in 1.0 V core supply (0.95 to 1.1 V); see decoupling network in power recommendations.
10 INH output Active-high PMOS open-drain output that drives VSLEEP rail level in all states except sleep, when it is released to an external pull-down (10 kΩ recommended).
11 VDDA3P3 power_in 3.3 V core supply (2.97 to 3.63 V); see decoupling network in power recommendations.
12 TRD_P bidirectional Positive differential transmit/receive MDI signal for IEEE 802.3bp 1000BASE-T1 operation.
13 TRD_M bidirectional Negative differential transmit/receive MDI signal for IEEE 802.3bp 1000BASE-T1 operation.
14 STRP_1 input Strap 1 pin (3-level, internal 6.3 kΩ pull-down) used to strap PHY_AD address bits.
15 RX_CTRL bidirectional RGMII receive control combining RX_DV (rising RX_CLK edge) and RX_ER (falling edge); a PHY_AD strap pin at reset and strap-only in SGMII mode.
16 CLKOUT/GPIO_2 bidirectional Clock output, 25 MHz buffered copy of XI by default; can be disabled by writing register 0x0453 = 0x0006.
17 DNC unconnected Do not connect; leave floating to avoid damage or entering a wrong PHY mode.
18 DNC unconnected Do not connect; leave floating to avoid damage or entering a wrong PHY mode.
19 DNC unconnected Do not connect; leave floating to avoid damage or entering a wrong PHY mode.
20 DNC unconnected Do not connect; leave floating to avoid damage or entering a wrong PHY mode.
21 VDD1P0 power_in 1.0 V core supply (0.95 to 1.1 V); see decoupling network in power recommendations.
22 VDDIO power_in IO supply of 1.8 V, 2.5 V or 3.3 V; see decoupling network in power recommendations.
23 RX_D3/RX_M output RGMII receive data bit 3 synchronous to RX_CLK, or SGMII differential data output RX_M to the MAC.
24 RX_D2/RX_P output RGMII receive data bit 2 synchronous to RX_CLK (also MAC[2] strap), or SGMII differential data output RX_P to the MAC.
25 RX_D1 output RGMII receive data bit 1 synchronous to RX_CLK; also MAC[1] interface-select strap.
26 RX_D0 output RGMII receive data bit 0 synchronous to RX_CLK; also MAC[0] interface-select strap.
27 RX_CLK output RGMII 125 MHz receive clock from PHY to MAC; unused in SGMII mode.
28 TX_CLK input RGMII 125 MHz transmit clock from MAC to PHY; unused in SGMII mode.
29 TX_CTRL input RGMII transmit control combining TX_EN (rising TX_CLK edge) and TX_ER (falling edge); unused in SGMII mode.
30 TX_D3 input RGMII transmit data bit 3 received from the MAC.
31 TX_D2 input RGMII transmit data bit 2 received from the MAC.
32 TX_D1/TX_P input RGMII transmit data bit 1 from the MAC, or SGMII differential data input TX_P.
33 TX_D0/TX_M input RGMII transmit data bit 0 from the MAC, or SGMII differential data input TX_M.
34 VDDIO power_in IO supply of 1.8 V, 2.5 V or 3.3 V; see decoupling network in power recommendations.
35 LED_0/GPIO_0 bidirectional LED_0 shows link status; also the MS strap (internal pull-down gives slave, external pull-up gives MDI master).
36 MDIO bidirectional Open-drain bidirectional management data signal requiring an external pull-up (2.2 kΩ recommended).
37 GND power_in Exposed die attach pad (DAP) ground; must be soldered to the PCB for thermal and mechanical performance.
