Noise Floor for Baseband Applications

15-Bit, 65Msps ADC with -79.3dBFSGeneral Description

The MAX1419 is a 5V, high-speed, high-performanceanalog-to-digital converter (ADC) featuring a fully differ- 65Msps Minimum Sampling Rateential wideband track-and-hold (T/H) and a 15-bit con- -79.3dBFS Noise Floor

verter core. The MAX1419 is optimized for multichannel,multimode receivers, which require the ADC to meet very Excellent Dynamic Performance

stringent dynamic performance requirements. With a76.2dB SNR at fIN=15MHz and AIN = -1dBFS

noise floor of -79.3dBFS, the MAX1427 allows for the93.1dBc/95.5dBc Single-Tone SFDR1/SFDR2 at design of receivers with superior sensitivity.

fIN = 15MHz and AIN = -1dBFS

The MAX1419 achieves two-tone, spurious-free dynamic-91dBc Multitone SFDR at fIN1 = 10MHz range (SFDR) of -91dBc for input tones of 10MHz andand fIN2 = 15MHz15MHz. Its excellent signal-to-noise ratio (SNR) of 76.2dB Less than 0.25ps Sampling Jitter

and single-tone SFDR performance (SFDR1/SFDR2) of93.1dBc/95.5dBc at f Fully Differential Analog Input Voltage Range of65Msps make this part ideal for high-performance digitalIN = 15MHz and a sampling rate of2.56VP-Preceivers.

CMOS-Compatible Two’s-Complement Data OutputThe MAX1419 operates from an analog 5V and a digital3V supply, features a 2.56V Separate Data Valid Clock and Overrange Outputsand allows for a sampling speed of up to 65Msps. TheP-Pfull-scale input range, Flexible-Input Clock Bufferinput T/H operates with a -1dB full-power bandwidth of200MHz.

The MAX1419 features parallel, CMOS-compatible out-puts in two’s-complement format. To enable the interfacewith a wide range of logic devices, this ADC provides aseparate output driver power-supply range of 2.3V to3.5V. The MAX1419 is manufactured in an 8mm x 8mm,56-pin thin QFN package with exposed paddle (EP) forlow thermal resistance, and is specified for the extendedOrdering Information
