Analog Devices Inc./Maxim Integrated MAX7060ATG/V+

Overview

MAX7060ATG/V+ from Maxim Integrated is a frequency- and power-programmable ASK/FSK RF transmitter IC operating from 280MHz to 450MHz, featuring a fully integrated fractional-N PLL synthesizer, programmable PA output power from +14dBm (5V) down to –14dBm, and ultra-fast 250µs startup time. It serves as the RF front-end in battery-powered remote control systems requiring FCC Part 15 or ETSI EN 300 220 compliance.

For engineers reviewing the MAX7060ATG/V+ datasheet, MAX7060ATG/V+ pinout, MAX7060ATG/V+ application, or MAX7060ATG/V+ equivalent, key selection criteria include its 28dB programmable transmit power range in 1dB steps, 70kbps Manchester-coded FSK data rate, automotive-grade –40°C to +125°C operation, and dual-mode configuration via SPI or manual pin control.

Technical Context

The MAX7060ATG/V+ implements a crystal-referenced fractional-N PLL with VCO gain of 340MHz/V and loop bandwidth of 300kHz, enabling precise carrier-frequency synthesis across its full 280–450MHz band using a single 15–16MHz crystal. Its phase noise is –78dBc/Hz at 10kHz offset (315MHz), supporting narrow-band superheterodyne receivers like MAX1473.

ASK modulation uses PA on/off switching with amplitude shaping via ROUT pin; FSK modulation achieves high accuracy by dynamically reprogramming PLL coefficients. The device supports both 3V (2.1–3.6V) and 5V (4.5–5.5V) supply modes, with internal regulators active in 5V mode and LSHDN-controlled 5nA shutdown in 3V mode.

FAQ

What is the minimum supply voltage required for MAX7060ATG/V+ operation?

The MAX7060ATG/V+ operates down to 2.1V in 3V mode, enabling direct use with depleted alkaline or lithium coin cells. At this voltage, output power remains adjustable from +10dBm to –14dBm. Below 2.1V, the internal POR circuit disables operation to prevent undefined behavior. The 5V mode requires 4.5V–5.5V and activates internal regulators for analog/RF blocks.

Does MAX7060ATG/V+ support both ASK and FSK modulation simultaneously?

No, the MAX7060ATG/V+ operates in either ASK or FSK mode, selected at configuration time via the GPO2_MOD pin (manual mode) or SPI register bit. Switching between modes requires reinitialization of the PLL and PA settings. Each mode has distinct data-rate limits: 50kbps Manchester ASK and 70kbps Manchester FSK - both verified to meet FCC/ETSI spectral masks.

How is the RF output power controlled on MAX7060ATG/V+?

MAX7060ATG/V+ implements digital power control via an 5-bit PApwr register (0x00 to 0x1E), providing 28dB range in 0.95dB steps. Power level is set through SPI writes or manual MSB/LSB pins (SDI_PWR1/SCLK_PWR0). The PA output stage is biased through PAVOUT, and matching is optimized using the programmable 0–7.75pF capacitor across PAOUT.

What is the purpose of the ROUT pin on MAX7060ATG/V+?

The ROUT pin on MAX7060ATG/V+ connects to an external resistor that sets the rise/fall time of ASK modulation envelope. This RC network reduces spectral splatter during PA switching, ensuring compliance with FCC Part 15 §15.231(a) and ETSI EN 300 220-1 bandwidth limits. Typical values range from 10kΩ to 100kΩ depending on desired shaping aggressiveness.

Is MAX7060ATG/V+ pin-compatible with other devices in the MAX7060 family?

Yes, MAX7060ATG/V+ shares identical pinout and footprint with MAX7060ATG+, MAX7060AETG+, and MAX7060AETG/V+. All variants use the same 24-pin TQFN-EP package and electrical pin functions. Differences are limited to temperature grade (industrial vs. automotive) and RoHS compliance marking; no PCB layout changes are needed when substituting within the family.
