MAX19713ETN+

Analog Front End (AFE) Overview

The MAX19713ETN+ is a mixed-signal analog front-end (AFE) operating in full-duplex mode. It integrates dual 10-bit, 45Msps receive ADCs and dual 10-bit, 45Msps transmit DACs. The device includes three 12-bit auxiliary DACs and one 10-bit auxiliary ADC. Typical power consumption is 91.8mW at a 45MHz clock frequency in full-duplex mode. It operates on a 2.7V to 3.3V analog supply and a 1.8V to 3.3V digital I/O supply. The component is housed in a 56-pin TQFN package with an exposed paddle.

Analog Front End (AFE) Feature Summary

• Ultra-low power: 91.8mW typical in FD mode at fCLK = 45MHz
• Three 12-bit, 1µs settling aux-DACs and one 10-bit, 333ksps aux-ADC
• Multiplexed parallel digital I/O with serial-interface control

Analog Front End (AFE) Applications

• WiMAX CPEs
• 802.11a/b/g WLAN
• VoIP Terminals
• Portable Communication Equipment

Analog Front End (AFE) Procurement Notes

Verify the ordering suffix '+', which indicates a lead-free package compliant with RoHS standards. Confirm the pin configuration matches the 56-pin TQFN-EP specification. Ensure the design supports the required 2.7V to 3.3V analog and 1.8V to 3.3V digital supply rails for proper operation within the specified temperature range.

Analog Front End (AFE) Selection Notes

Select this part for wideband communication systems requiring simultaneous transmission and reception. The MAX19713 is optimized for frequency-division duplex applications. For time-division duplex designs, consider the MAX19705–MAX19708 family instead. Verify that the system can accommodate the 56-pin TQFN footprint and thermal requirements.

Analog Front End (AFE) Part Context

This component belongs to the MAX197xx AFE family from Analog Devices/Maxim Integrated. It provides pin-compatible alternatives within the series. The 'ETN' designation specifies the 56-pin TQFN package code. The '+' suffix denotes a lead-free manufacturing process.

Analog Front End (AFE) Replacement Considerations

Consult the data sheet selector guide for other pin-compatible versions within the MAX197xx family. For time-division duplex implementations, evaluate the MAX19705 through MAX19708 series as functional substitutes.
