ONET1130ECRSMT from Texas Instruments, in a VQFN-32-EP(4x4). 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 | LOL | output | Transmitter and receiver loss of lock indicator; open drain output (3.3 V tolerant) that requires an external 4.7-10 kΩ pull-up resistor to VCC. |
| 2 | MONB | output | Bias current monitor output. |
| 3 | GND | power_in | Circuit ground. |
| 4 | TXIN+ | input | Non-inverted transmitter data input with on-chip 100 Ω differential termination to TXIN-; must be AC coupled. |
| 5 | TXIN- | input | Inverted transmitter data input with on-chip 100 Ω differential termination to TXIN+; must be AC coupled. |
| 6 | GND | power_in | Circuit ground. |
| 7 | PD | bidirectional | Photodiode input capable of sourcing or sinking current based on register setting. |
| 8 | MONP | output | Photodiode current monitor output. |
| 9 | TX_LF | input | Transmitter loop filter capacitor connection. |
| 10 | BIAS | bidirectional | Laser bias current pin that sinks or sources bias current for both APC and open-loop modes. |
| 11 | VCC_TX | power_in | 2.5 V ± 5% supply voltage for the transmitter. |
| 12 | TXOUT- | output | Inverted transmitter data output internally terminated in single-ended operation mode. |

| 14 | VCC_TX | power_in | 2.5 V ± 5% supply voltage for the transmitter. |
| 15 | VDD | power_in | 2.5 V ± 5% supply voltage for the digital circuitry. |
| 16 | AMP | input | Output amplitude control input (0-2 V range) to adjust transmitter output amplitude; leave open when not used. |
| 17 | SDA | bidirectional | 2-wire serial data input/output (3.3 V tolerant) requiring an external 4.7-10 kΩ pull-up resistor to VCC. |
| 18 | SCK | input | 2-wire serial clock input (3.3 V tolerant) requiring an external 4.7-10 kΩ pull-up resistor to VCC. |
| 19 | GND | power_in | Circuit ground. |
| 20 | RXIN+ | input | Non-inverted receiver data input with on-chip 100 Ω differential termination to RXIN-; must be AC coupled. |
| 21 | RXIN- | input | Inverted receiver data input with on-chip 100 Ω differential termination to RXIN+; must be AC coupled. |
| 22 | GND | power_in | Circuit ground. |
| 23 | COMP | input | APC loop compensation pin; connect a 0.01 µF capacitor to ground for bandwidth control. |
| 24 | RX_LOS | output | Receiver loss of signal indicator; open drain output (3.3 V tolerant) that requires an external 4.7-10 kΩ pull-up resistor to VCC. |
| 25 | RX_LF | input | Receiver loop filter capacitor connection. |
| 26 | RX_DIS | input | Receiver output buffer disable input (3.3 V tolerant) with integrated 250 kΩ pull-up to VCC; ground to enable, high to disable. |
| 27 | VCC_RX | power_in | 2.5 V ± 5% supply voltage for the receiver. |
| 28 | RXOUT- | output | Inverted receiver data output with 45 Ω back termination to VCC. |
| 29 | RXOUT+ | output | Non-inverted receiver data output with 45 Ω back termination to VCC. |
| 30 | VCC_RX | power_in | 2.5 V ± 5% supply voltage for the receiver. |
| 31 | TX_FLT | output | Transmitter fault detection flag; open drain output (3.3 V tolerant) that requires an external 4.7-10 kΩ pull-up resistor to VCC. |
| 32 | TX_DIS | input | Transmitter bias and modulation disable input (3.3 V tolerant) with integrated 250 kΩ pull-up to VCC; high disables both bias and modulation currents, can toggle to reset fault. |
| 33 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
