MAX5863
Ultra-Low-Power, High-Dynamic Performance, 7.5Msps Analog Front End
Maxim Confidential 
MyMaxim SubscriptionsProduct Details
The ADCs and DACs operate simultaneously or independently for frequency-division duplex (FDD) and time-division duplex (TDD) modes. A 3-wire serial interface controls power-down and transceiver modes of operation. The typical operating power is 22.8mW at fCLK = 7.5Msps with the ADCs and DACs operating simultaneously in transceiver mode. The MAX5863 features an internal 1.024V voltage reference that is stable over the entire operating power-supply range and temperature range. The MAX5863 operates on a +2.7V to +3.3V analog power supply and a +1.8V to +3.3V digital I/O power supply for logic compatibility. The quiescent current is 3.5mA in Idle Mode™ and 1µA in shutdown mode. The MAX5863 is specified for the extended (-40°C to +85°C) temperature range and is available in a 48-pin thin QFN package. See a parametric table of the complete family of pin-compatible AFEs.

Description
The MAX5865 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the MAX5865 40Msps analog front end. The MAX5865 integrates a dual-channel analog-to-digital converter (ADC), a dual-channel digital-to-analog converter (DAC), and a 1.024V internal voltage reference. The EV kit board accepts AC- or DC-coupled, differential or single-ended analog inputs for the receive ADC and includes circuitry that converts the transmit DAC differential output signals to single-ended analog outputs. The EV kit includes circuitry that generates a clock signal from an AC sine wave input signal. The EV kit operates from a +3.0V analog power supply, +3.0V digital power supply, and ±5V bipolar power supply.
The EV kit comes with Windows® 98/2000/XP-compatible software that provides an interface to exercise the features of the MAX5865. The program is menu driven and offers a graphical user interface (GUI) with control buttons and status displays. The GUI is used to control the MAX5865 SPI-compatible serial interface.
The MAX5865 EV kit evaluates the 22Msps MAX5864 or the 7.5Msps MAX5863 analog front end (IC replacement is required).
Features
- Quick Dynamic Performance Evaluation
- 50Ω Matched Clock Input and Analog Signal Lines
- Single-Ended to Fully Differential Analog Input Signal Configuration
- Differential to Single-Ended Output Signal-Conversion Circuitry
- AC- or DC-Coupled Input Signals Configuration
- SMA Coaxial Connectors for Clock Input, Analog Inputs, and Analog Output
- On-Board Clock-Shaping Circuit
- High-Speed PC Board Design
- Fully Assembled and Tested
- Windows-Compatible Software
