CLC5956 12-bit/ 65 MSPS Broadband Monolithic A/D Converter

The CLC5956 is a monolithic 12-bit, 65 MSPS analog-to-digital converter subsystem. The device has been optimized for use in cellular base stations and other applications where high resolution, high sampling rate, wide dynamic range, low power dissipation, and compact size are required. The CLC5956 features differential analog inputs, low jitter differential .

Features

differential analog inputs, low jitter differential PECL clock inputs, a low distortion track-and-hold with DC to 300 MHz input bandwidth, a bandgap voltage reference, TTL compatible CMOS output logic, and a proprietary 12-bit multi-stage quantizer. The CLC5956 is fabricated on the ABIC-IV 0.8 micron BiCMOS process. The part features a 73 dB spurious free dynamic range (SFDR) and 67 dB SNR. The wideband track-and-hold allows sampling of IF signals to greater than 250 MHz. The part produces two-tone, dithered, spurious-free dynamic range of 83 dBFS at 75 MHz input frequency.
