MAX19713ETN

Analog Front End (AFE) Overview

The MAX19713ETN is a low-power, high-integration mixed-signal analog front end (AFE) operating in full-duplex mode for broadband communication systems. It integrates dual 10-bit, 45Msps receive ADCs and dual 10-bit, 45Msps transmit DACs, alongside three fast-settling 12-bit auxiliary DACs and one 10-bit, 333ksps auxiliary ADC. The device achieves typical power consumption of 91.8mW at a 45MHz clock frequency in full-duplex mode. It supports independent shutdown of the Rx ADC and Tx DAC for optimized power management and operates on a 2.7V to 3.3V analog supply with a 1.8V to 3.3V digital I/O supply.

Analog Front End (AFE) Feature Summary

• Dual 10-bit, 45Msps Rx ADCs and dual 10-bit, 45Msps Tx DACs
• Low power consumption: 91.8mW (full-duplex), 79.2mW (low-speed Rx), 49.5mW (low-speed Tx)
• Auxiliary control: Three 12-bit, 1µs auxiliary DACs and one 10-bit, 333ksps auxiliary ADC
• Excellent gain/phase matching: ±0.03° phase and ±0.02dB gain for Rx ADC

Analog Front End (AFE) Applications

• 802.11a/b/g WLAN
• Portable communication devices
• VoIP terminals
• WiMAX CPE

Analog Front End (AFE) Procurement Notes

Verify the specific suffix ETN against official Analog Devices documentation to confirm package type and temperature range. Confirm current production status as older Maxim Integrated products may be discontinued or subject to limited availability. Ensure compatibility with required 2.7V-3.3V analog and 1.8V-3.3V digital power supplies during sourcing.

Analog Front End (AFE) Selection Notes

Select this component for full-duplex broadband applications requiring high dynamic performance with minimal power usage. Compare against the MAX19710-MAX19713 family for pin-compatible alternatives. For time-division duplex (TDD) systems, consider the MAX19705-MAX19708 series instead. Verify that the 56-pin thin QFN (7mm x 7mm x 0.8mm) footprint fits the design constraints.

Analog Front End (AFE) Part Context

The MAX19713 belongs to the MAX1971x AFE family from Analog Devices (formerly Maxim Integrated). These devices are designed for wideband communication infrastructure, offering integrated RF front-end functionality to reduce system complexity. The ETN suffix typically denotes a specific thermal and packaging variant within the broader MAX19713 product line.

Analog Front End (AFE) Replacement Considerations

Check for pin-compatible members of the MAX1971x family (MAX19710, MAX19711, MAX19712) if different channel counts or specifications are acceptable. For TDD applications, evaluate the MAX19705–MAX19708 series.
