Product details
Overview
ATR2406-PNQG from Microchip Technology (formerly Atmel) is a fully integrated 2.4 GHz ISM band low-IF transceiver in QFN32 (5 × 5 × 0.9 mm) package, featuring integrated LNA (−93 dBm sensitivity), +4 dBm TX output, GFSK modulation at 72–1152 kBit/s, and on-chip clock recovery for 1152 kBit/s data streams - deployed in wireless game controllers and telemetry systems.
For engineers reviewing the ATR2406-PNQG datasheet, ATR2406-PNQG pinout, ATR2406-PNQG application, or ATR2406-PNQG equivalent, key selection considerations include its 95-channel frequency-hopping capability, auxiliary 3.2–4.6 V regulator support, 3-wire SPI interface timing (10 MHz max), and compliance with FCC Part 15, ETSI EN 300 328, and ARIB STD-T-66.
Technical Context
The ATR2406-PNQG implements a low-IF architecture with 864 kHz IF frequency, image-rejection mixer, integrated Gaussian filter, and fully integrated VCO with on-chip inductors and varactors. Its PLL uses a 1.728 MHz phase detector frequency and supports programmable main/swallow counters for precise channel tuning across 95 channels.
It delivers clock recovery synchronized to the transmitter's clock via RX-CLOCK (Pin 6), enabling optimal sampling of RX_DATA on the falling edge - eliminating external clock distribution overhead. The ramp generator (RAMP_OUT, Pin 21) provides controlled voltage steps (1.3–1.75 V) for external PA power ramping per D12/D13 register settings.

Pinout & Package
ATR2406-PNQG is housed in a lead-free QFN32 package (5 × 5 × 0.9 mm) with exposed thermal paddle (GND). All pins are surface-mount compatible; IC-labeled pins (7, 22, 23) are internal connections and must remain unconnected on PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PU_REG (1) | Auxiliary regulator enable | Activates on-chip 3.2–4.6 V regulator and VCO supply - required before PU_TRX for full power-up sequence. |
| REF_CLK (2) | Reference clock input | Accepts 10.368 MHz or 13.824 MHz sinusoidal input (250–500 mVRMS) - sets PLL reference for channel accuracy. |
| RSSI (3) | Analog received signal strength indicator | Outputs 0.3–2.1 V linearly proportional to RF input level (−96 to −36 dBm) - used for link quality monitoring. |
| VS_IFD (4) | Digital IF supply | Provides dedicated 2.9–3.6 V rail for digital IF circuits - decoupling critical for clock recovery stability. |
| RX-CLOCK (6) | Recovered clock output | Falling-edge-aligned clock for RX_DATA sampling - eliminates need for external clock recovery circuitry at 1152 kBit/s. |
| RX_IN1/RX_IN2 (18–19) | Differential RF input | Accepts balanced 50 Ω antenna signal - high IIP3 (−15 dBm) ensures robustness against interferers in dense 2.4 GHz environments. |
| TX_OUT (20) | Transmit driver output | Delivers +4 dBm into 50 Ω load - requires external balun/filter (e.g., µStrip) per Figure 7 for spectral compliance. |
| RAMP_OUT (21) | PA ramp control output | Generates 1.3–1.75 V ramp per D12/D13 register setting - controls external PA turn-on/turn-off to meet spurious emission limits. |
| TX_ON (25) | Transmit activation control | Edge-triggered enable for TX path - initiates RAMP_OUT sequence and activates PA; must be timed per Figure 5. |
| PU_TRX (27) | Core transceiver power-up | Enables RX/TX/PLL/VCO blocks after PU_REG - minimum 40 µs delay required before programming or operation. |
| RX_DATA (28) | Demodulated data output | CMOS-level serial data stream - sampled on falling edge of RX-CLOCK (Pin 6) when clock recovery is active. |
| TX_DATA (29) | Baseband data input | Accepts GFSK-modulated bitstream - filtered internally by Gaussian filter with GFCS-adjustable deviation (±400 kHz nominal). |
| CLOCK/DATA/ENABLE (30–32) | 3-wire SPI interface | Asynchronous serial bus for register configuration - no handshake; latched on ENABLE rising edge after MSB-first transfer. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2.4 GHz ISM transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CC2530F256RHAT | Integrated 8051 MCU + 256 kB flash; lower RX sensitivity (−97 dBm); Zigbee/Proprietary stack support | Requires embedded protocol stack development; better suited for mesh networks than point-to-point streaming | Select when MCU co-location and Zigbee compatibility are required; not drop-in for ATR2406-PNQG's standalone transceiver use case |
| nRF24L01+ | No integrated clock recovery; lower TX power (+0 dBm); proprietary 250 kBit/s–2 MBit/s GFSK; no auxiliary regulator | Lacks 1152 kBit/s clock recovery and 3.2–4.6 V auxiliary input - needs external LDO for battery operation | Choose for cost-sensitive, lower-throughput applications where MCU handles clock recovery; verify regulatory testing coverage separately |
Compared with CC2530F256RHAT and nRF24L01+, the ATR2406-PNQG uniquely combines clock recovery at 1152 kBit/s, integrated auxiliary regulation, and ETSI/FCC/ARIB triple compliance - making it optimal for latency-critical, battery-powered, standards-certified 2.4 GHz links without embedded software overhead.

FAQ
What is the maximum data rate supported by the ATR2406-PNQG with on-chip clock recovery?
The ATR2406-PNQG supports on-chip clock recovery exclusively at 1152 kBit/s GFSK modulation. At this rate, the recovered clock is output on Pin 6 (RX-CLOCK), with data sampled on its falling edge. Lower rates (72–576 kBit/s) require external clocking - the ATR2406-PNQG does not provide clock recovery functionality below 1152 kBit/s.
Does the ATR2406-PNQG require external matching components for its RF ports?
Yes, the ATR2406-PNQG requires external balun and low-pass filtering for both RX_IN1/RX_IN2 and TX_OUT. Figure 7 in the datasheet shows a µStrip balun and lowpass filter implementation. These components are mandatory to meet FCC/ETSI spectral mask requirements and ensure impedance matching to 50 Ω antennas - omitting them results in out-of-band emissions exceeding regulatory limits.
How does the auxiliary voltage regulator in the ATR2406-PNQG function, and what supply range does it accept?
The ATR2406-PNQG's auxiliary regulator accepts 3.2–4.6 V input (VS_REG, Pin 11) and generates 3.0 V (VREG, Pin 10) and 2.7 V (VREG_VCO, Pin 13) outputs. It is enabled via PU_REG (Pin 1) and powers the VCO and analog sections. This allows direct connection to single-cell Li-ion (3.6 V nominal) or alkaline batteries without external regulators - the ATR2406-PNQG itself does not regulate the main 2.9–3.6 V VS_TRX supply.
Can the ATR2406-PNQG operate without the auxiliary regulator enabled?
Yes, the ATR2406-PNQG can operate without the auxiliary regulator: PU_REG is held low, and the main supply (VS_TRX, Pin 17) must be 2.9–3.6 V. In this mode, internal VCO and analog supplies are derived from VS_TRX, resulting in reduced TX output power stability and narrower temperature margin. The ATR2406-PNQG datasheet specifies +4 dBm output only "with AUX regulator" - operation without it requires validation per application conditions.
What is the purpose of the RAMP_OUT pin (Pin 21) on the ATR2406-PNQG, and how is its voltage controlled?
RAMP_OUT (Pin 21) provides a programmable voltage ramp to control an external power amplifier's turn-on/turn-off timing. Its output voltage is set by D12/D13 bits in the TX register: 00=1.3 V, 01=1.35 V, 10=1.4 V, 11=1.75 V. This ramp starts on assertion of TX_ON (Pin 25) and ensures compliant spectral occupancy during PA switching - critical for passing FCC/ETSI spurious emission tests.
