Quad, 12-Bit, 65Msps, 1.8V ADC with

Serial LVDS Outputs

General Description

Features

The MAX1127 quad, 12-bit analog-to-digital converter

(ADC) features fully differential inputs, a pipelined

architecture, and digital error correction. This ADC is

optimized for low-power, high-dynamic performance for

medical imaging, communications, and instrumentation

applications. The MAX1127 operates from a 1.7V to

1.9V single supply and consumes only 563mW while

delivering a 69.6dB signal-to-noise ratio (SNR) at a

19.3MHz input frequency. In addition to low operating

power, the MAX1127 features a 675µA power-down

mode for idle periods.

♦ Four ADC Channels with Serial LVDS/SLVS

Outputs

♦ Excellent Dynamic Performance

69.6dB SNR at f = 19.3MHz

92dBc SFDR at f = 19.3MHz

-87dB Channel Isolation

♦ Ultra-Low Power

135mW per Channel (Normal Operation)

1.2mW Total (Shutdown Mode)

♦ Accepts 20% to 80% Clock Duty Cycle

♦ Self-Aligning Data-Clock to Data-Output Interface

♦ Fully Differential Analog Inputs

Differential Input Voltage Range

♦ Internal/External Reference Option

♦ Test Mode for Digital Signal Integrity

An internal 1.24V precision bandgap reference sets the

ADC’s full-scale range. A flexible reference structure

allows the use of an external reference for applications

requiring increased accuracy or a different input volt-

age range.

♦ Wide ±1.4V

P-P

A single-ended clock controls the conversion process.

An internal duty-cycle equalizer allows for wide varia-

tions in input-clock duty cycle. An on-chip phase-

locked loop (PLL) generates the high-speed serial

low-voltage differential signaling (LVDS) clock.

♦ LVDS Outputs Support Up to 30in FR-4 Backplane

Connections

♦ Small, 68-Pin QFN with Exposed Paddle

♦ Evaluation Kit Available (MAX1127EVKIT)

The MAX1127 provides serial LVDS outputs for data,

clock, and frame alignment signals. The output data is

presented in two’s complement or binary format.
