Single/Dual, 14-Bit 250Msps ADC Family Provides High SFDR Undersampling Performance

Linear Technology Corporation introduces a family of dual and single high IF sampling 14-bit, 170Msps, 210Msps and 250Msps analog-to-digital converters (ADCs) that maintain good SFDR performance at input frequencies up to 900MHz. The LTC2152-14 and LTC2157-14 are single and dual channel simultaneous sampling ADCs, respectively, offering double data rate (DDR) LVDS digital outputs. These ADCs are specifically designed to meet the needs of today’s communications systems, where high undersampling capability reduces costs by eliminating downconversion stages.

Operating from a single 1.8V supply, the dual LTC2157-14 consumes 303mWper channel at 250Msps and offers signal to noise ratio (SNR) performance of 70dB and SFDR of 90dB at baseband with an easy-to-drive 1.5Vp-p input range. Pin-compatible speed grade options include 170Msps and 210Msps in 14-bit and 12-bit resolutions. Analog full power bandwidth of 1.25GHz and ultralow jitter of 0.15psRMS enables undersampling of IF frequencies with excellent noise performance.

Available in compact 9mm x 9mm (dual) and 6mm x 6mm (single) QFN packages, the ADCs are offered in commercial or industrial temperature grades. Demonstration boards and samples are immediately available.
