CA-IF4023 from Chipanalog, in a QFN-16-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 | SYNCOUT | output | Synchronized clock output that passes the XTAL1/2 source clock through an open-drain stage, with a 1kΩ pull-up to VCC recommended and an absolute limit of VCC+0.3V on the port voltage. |
| 2 | TXIN | input | Digital data input to the transmitter; it is a logic input referenced to VL with a high threshold of 0.7×VL minimum and a low threshold of 0.3×VL maximum. |
| 3 | VL | power_in | Logic supply input, specified from 1.6V to 5.5V (recommended 1.6V to 5.5V, typical 3.3V). |
| 4 | RXOUT | output | Digital output carrying the demodulated received signal, referenced to VL. |
| 5 | DIR | output | Signal-direction indicator logic output that goes high when a signal is detected on RXIN and is referenced to VL. |
| 6 | DIRMD2 | input | Data-rate control bit 2 (with DIRMD1 sets 9.6, 38.4 or 115.2kbps, or standby when both are high); it is internally pulled down to GND through a resistor. |
| 7 | DIRMD1 | input | Data-rate control bit 1 (with DIRMD2 sets 9.6, 38.4 or 115.2kbps, or standby when both are high); it is internally pulled down to GND through a resistor. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | RES | input | Transmitter output power control node; an external resistor divider from BIAS (R1 4.1kΩ) to RES and from RES to GND (R2 10kΩ) sets the TXOUT amplitude, with RES voltage in the range 0.7V to 1.5V. |
| 10 | BIAS | output | Reference voltage output (1.5V nominal) that feeds the RES divider; a 1µF decoupling capacitor to GND is recommended. |
| 11 | RXIN | input | Receiver signal input for the 2.176MHz OOK signal, accepting a maximum input of 1.12VP-P, with a 100nF AC-coupling capacitor to the cable. |
| 12 | TXOUT | output | Transmitter output to the coax cable at 2.176MHz, with amplitude set by the RES network (about 1.17 to 2.52VP-P) and short-circuit current limited to ±200mA. |
| 13 | VCC | power_in | Analog supply input, specified from 3.0V to 5.5V. |
| 14 | XTAL1 | input | Crystal input for the 8.704MHz carrier, or an external clock/oscillator input; if driven directly by an oscillator or PLL output, XTAL2 must be tied to GND. |
| 15 | XTAL2 | input | Second crystal connection for the 8.704MHz carrier; it must be tied to GND when XTAL1 is driven directly by an external clock. |
| 16 | GND | power_in | Ground reference for the device. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
