# NJM14570RB1-TE1

**JRC** · IC · MSOP-8

NJM14570RB1-TE1 from JRC, in a MSOP-8. 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 | DET OUT | output | FM detector output, which the terminal table gives as about 1.5 V DC with no signal at V+ = 3 V. |
| 2 | QUAD COIL | passive | FM detector input connected to the phase-shift (quadrature) circuit, about 3.0 V DC with no signal at V+ = 3 V. |
| 3 | V+ | power_in | Supply voltage pin with a recommended range of 1.8 V to 9 V and an absolute maximum rating of 10 V. |
| 4 | RSSI OUT | output | Received signal strength indicator output that gives a DC level proportional to the log of the IF input level on pin 5. |
| 5 | IF IN | input | IF amplifier input, about 2.6 V DC with no signal at V+ = 3 V. |
| 6 | GND | power_in | Ground terminal at 0.0 V. |
| 7 | DECOUPLE1 | passive | IF decoupling pin for an external capacitor that sets IF amplifier bandwidth, where a large capacitor gives wide band and a small capacitor gives narrow band. |
| 8 | DECOUPLE2 | passive | IF decoupling pin for an external capacitor that sets IF amplifier bandwidth, where a large capacitor gives wide band and a small capacitor gives narrow band. |
