Texas Instruments · Ethernet Transceivers · HVQFN-24-EP(3x3)

DP83825IRMQR from Texas Instruments, in a HVQFN-24-EP(3x3). 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 TX_EN input RMII transmit enable, active high, presented on the rising edge of TX_CLK to indicate valid data on TX_D[1:0].
2 50MHzOut/LED2/S (RX_DV_En) output Outputs a 50MHz clock in RMII leader mode (default) or drives LED2 in follower mode; can be configured as GPIO by register.
3 INTR/PWRDN bidirectional Power-down by default: an active low signal places the device in power-down; as interrupt it is an open-drain output asserted low with a weak internal 9.5kΩ pullup.
4 LED0/S (ANEG_Dis) output Activity and link LED output, always at 3.3V regardless of VDDIO to avoid external components when operating at VDDIO 1.8V.
5 RST_N input Active low reset input; it must be asserted low for at least 25μs to force a reset and re-scan of the straps.
6 VDDA3V3 power_in Analog supply input at 3.3V (recommended 3V to 3.6V); see Section 8.3 for decoupling requirements.
7 RD_M input Differential receive input (PMD) automatically configured to accept either 10BASE-Te or 100BASE-TX signaling.
8 RD_P input Differential receive input (PMD) automatically configured to accept either 10BASE-Te or 100BASE-TX signaling.
9 GND power_in Ground connection.
10 TD_M output Differential transmit output (PMD) configured for 10BASE-Te or 100BASE-TX signaling based on the PHY configuration.
11 TD_P output Differential transmit output (PMD) configured for 10BASE-Te or 100BASE-TX signaling based on the PHY configuration.
12 XO output Crystal output used for crystal only; it can be left floating when a CMOS-level oscillator drives XI.
13 XI/50MHzIn input Crystal or oscillator input: 25MHz ±50ppm in RMII leader mode, 50MHz ±50ppm CMOS-level oscillator in RMII follower mode.
14 RBIAS passive Requires a 6.49kΩ ±1% bias resistor connected between RBIAS and ground.
15 MDIO bidirectional Management data I/O with internal 10kΩ pullup; an external pullup of up to 2.2kΩ can be added if needed.
16 MDC input Management data clock for MDIO, maximum rate 24MHz with no minimum clock rate.
17 RX_D1 output RMII receive data bit 1, synchronous to the reference clock; valid when RX_DV is asserted. Also the leader/follower mode strap.
18 RX_D0/S (PhyAdd[0]) output RMII receive data bit 0, synchronous to the reference clock; valid when RX_DV is asserted. Also the PHY address strap bit 0.
19 VDDIO power_in I/O supply input at 3.3V or 1.8V (3.3V range 3V to 3.6V; 1.8V range 1.62V to 1.98V).
20 CRS_DV/S (PhyAdd[1]) output RMII carrier sense and receive data valid indication combined on one pin; also the PHY address strap bit 1.
21 GND power_in Ground pin.
22 RX_ER/S (A-MDIX) output RMII receive error output asserted high synchronously to the rising reference clock; not required by the MAC because the PHY corrupts data on error. Also the Auto-MDIX strap.
23 TX_D0 input RMII transmit data bit 0 from the MAC, synchronous to the rising edge of the reference clock.
24 TX_D1 input RMII transmit data bit 1 from the MAC, synchronous to the rising edge of the reference clock.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
