CLC5956 12-bit, 65 MSPS Broadband Monolithic A/D Converter June 1999 CLC5956 12-bit, 65 MSPS Broadband Monolithic A/D Converter General Description 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 pact size are required. The CLC5956 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 patible CMOS output logic, and a proprietary 12-bit multi-stage quantizer. The CLC5956 is fabricated on the ABIC-IV 0.8 micron Bi CMOS process. The part Features a 73 d B spurious free dynamic range (SFDR) and 67 d B 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 d BFS at 75 MHz input frequency. The differential analog input provides excellent mon-mode rejection, while the differential PECL clock inputs permit the use of balanced transmission to minimize jitter in distributed systems. The 48-pin TSSOP package provides an extremely small footprint for applications where space is a critical consideration. The CLC5956 operates from a single +5V power supply over the industrial temperature range of - 40˚C to +85˚C. National thoroughly tests each part to verify full pliance with the guaranteed specifications.
