Description

The LTC2207/LTC2206 are 105Msps/80Msps, sampling 16-bit A/D converters designed for digitizing high frequency, wide dynamic range signals up to input frequencies of 700MHz. The input range of the ADC can be optimized with the PGA front end.

The LTC2207/LTC2206 are perfect for demanding communications applications, with AC performance that includes 78.2dB Noise Floor and 100dB spurious free dynamic range (SFDR). Ultralow jitter of 80fsRMS allows undersampling of high input frequencies with excellent noise performance. Maximum DC specs include ±4LSB INL, ±1LSB DNL (no missing codes) over temperature.

A separate output power supply allows the CMOS output swing to range from 0.5V to 3.6V.

The ENC+ and ENC– inputs may be driven differentially or single-ended with a sine wave, PECL, LVDS, TTL or CMOS inputs. An optional clock duty cycle stabilizer allows high performance at full speed with a wide range of clock duty cycles.

Simulate

Linear Technology offers free software and demo boards that greatly simplify the task of testing and evaluating our data converters. To use these powerful tools with the LTC2207:

  1. Download the PScope (QuickEval II) System software. The PScope System is a USB-based product demonstration and data acquisition system for use with Linear Technologys high performance analog to digital converters. The software also includes web links to the appropriate device data sheets and provides an automatic update feature to keep the software current with the latest set of device drivers.

  2. Request the DC718 QuickDAATS USB Controller either online or from your local sales representative. The DC718 QuickDAATs USB Controller interfaces with the USB port of your computer and connects to the LTC2207 daughter cards.

  3. Request the DC918C-A or DC918C-B either online or from your local sales representative. The DC918C allows easy evaluation of the LTC2207 from your PC.

    • DC918C-A: Fin  = 1MHz to 70MHz
    • DC918C-B: Fin = 70MHz to 140MHz

  4. For DC input signals or single-ended clock requirements, request the DC919A-A from your local sales representative

    • DC919A-A: Fin  = DC to 70MHz
