The MAX1003 is a dual, 6-bit analog-to-digital converter (ADC) that combines high-speed, low-power operation with a user-selectable input range, an internal reference, and a clock oscillator. The dual parallel ADCs are designed to convert in-phase (I) and quadrature (Q) analog signals into two 6-bit, offset-binary-coded digital outputs at sampling rates up to 90Msps. The ability to directly interface with baseband I and Q signals makes the MAX1003 ideal for use in direct-broadcast satellite, VSAT, and QAM16 demodulation applications.

The MAX1003 input amplifiers feature true differential inputs, a -0.5dB analog bandwidth of 55MHz, and user-programmable input full-scale ranges of 125mVp-p, 250mVp-p, or 500mVp-p. With an AC-coupled input signal, matching performance between input channels is typically better than 0.1dB gain, 1/4LSB offset, and 0.5° phase. Dynamic performance is 5.85 effective number of bits (ENOB) with a 20MHz analog input signal, or 5.7 ENOB with a 50MHz signal.

The MAX1003 operates with +5V analog and +3.3V digital supplies for easy interfacing to +3.3V-logic-compatible digital signal processors and microprocessors. It comes in a 36-pin SSOP package.

Applications

  • Cable Television Set-Top Boxes

Product Detail

The MAX1002/MAX1003 evaluation kits (EV kits) simplify evaluation of the 60Msps MAX1002 and 90Msps MAX1003 dual, 6-bit analog-to-digital converters (ADCs). The kits include the basic components necessary to operate the on-chip oscillator as a voltage-controlled oscillator (VCO). Each board can also be easily modified to accommodate an external clocking source.

Connectors for power supplies, analog inputs, and digital outputs simplify connections to the device. The PC board features an optimized layout to ensure the best possible dynamic performance. The EV kits include a MAX1002 or MAX1003.
