HR911130A from HANRUN(Zhongshan HanRun Elec), in a Through Hole. Symbol, footprint and 3D model are the ones used on Adom board designs (3D model: Adom-generated 3D model built from the datasheet dimensions (simplified; CC-BY-SA 4.0); no vendor CAD is redistributed). Pin functions are extracted from the manufacturer datasheet with page references.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | P1 | passive | Common centre tap of the four chip-side transformer windings (the drawing labels it P1 only). [datasheet p.1] |
| 2 | MDI0+ | passive | MDI 0+ (P2): chip-side winding of a 1CT:1CT transformer; reaches jack contact J1 (A+) through the common-mode choke. [datasheet p.1] |
| 3 | MDI0- | passive | MDI 0- (P3): chip-side winding of a 1CT:1CT transformer; reaches jack contact J2 (A-) through the common-mode choke. [datasheet p.1] |
| 4 | MDI1+ | passive | MDI 1+ (P4): chip-side winding of a 1CT:1CT transformer; reaches jack contact J3 (B+) through the common-mode choke. [datasheet p.1] |
| 5 | MDI2+ | passive | MDI 2+ (P5): chip-side winding of a 1CT:1CT transformer; reaches jack contact J4 (C+) through the common-mode choke. [datasheet p.1] |
| 6 | MDI2- | passive | MDI 2- (P6): chip-side winding of a 1CT:1CT transformer; reaches jack contact J5 (C-) through the common-mode choke. [datasheet p.1] |
| 7 | MDI1- | passive | MDI 1- (P7): chip-side winding of a 1CT:1CT transformer; reaches jack contact J6 (B-) through the common-mode choke. [datasheet p.1] |
| 8 | MDI3+ | passive | MDI 3+ (P8): chip-side winding of a 1CT:1CT transformer; reaches jack contact J7 (D+) through the common-mode choke. [datasheet p.1] |
| 9 | MDI3- | passive | MDI 3- (P9): chip-side winding of a 1CT:1CT transformer; reaches jack contact J8 (D-) through the common-mode choke. [datasheet p.1] |
| 10 | P10 | passive | Termination return: each cable-side centre tap goes through 75 ohms (4 x 75 ohms) to a common node, which reaches P10 through a 1000 pF 2 kV capacitor. [datasheet p.1] |
| 11 | 11 | passive | Green LED anode; the cathode is pin 12 (schematic p.1). Left LED seen from the front; 568 nm, forward voltage 1.8 V min / 2.8 V max at 20 mA. [datasheet p.2] |
| 12 | 12 | passive | Green LED cathode; the anode is pin 11. [datasheet p.1] |
| 13 | 13 | passive | Yellow LED cathode; the anode is pin 14. [datasheet p.1] |
| 14 | 14 | passive | Yellow LED anode; the cathode is pin 13 (schematic p.1). Right LED seen from the front; 585 nm, forward voltage 1.8 V min / 2.8 V max at 20 mA. [datasheet p.2] |
| S1 | SHIELD | passive | Shield pin in one of the two 1.63 mm plated holes of the recommended PCB layout (the drawing gives it no name). [datasheet p.3] |
| S2 | SHIELD | passive | Shield pin in one of the two 1.63 mm plated holes of the recommended PCB layout (the drawing gives it no name). [datasheet p.3] |
