CLC935

Comlinear CLC935 12-bit, 15MSPS A/D Converter Augus 1996 N Comlinear CLC935 12-bit, 15MSPS A/D Converter General Description The Comlinear CLC935 is a high-speed high-performance 12-bit Analog-to-Digital converter. the CLC935 is a complete A/D subsystem, including 12-bit quantizer, track-and-hold, and references. The ECL compatible A/D has maximum sample rates of 15MSPS, allowing the user to digitize high-speed signals accurately. The CLC935 has excellent dynamic performance characteristics which are thoroughly tested to insure that system performance goals will be met. Sampling at 15MSPS with a 400kHz input signal, the CLC935 achieves a typical 82dBc SFDR and an SNR of 65.5dB. Sampling a 5MHz signal can be done with 78dB of SFDR. The CLC935 incorporates a complete two-pass architecture which is constructed from high-speed IC’s on a thin-film substrate. Critical DC parameters are laser trimmed to assure accurate part-to-part matching. A CONVERT clock, power, and an analog input signal are all that are required for CLC935 operation. The CLC935-BC part is specified over the commercial temperature range, while the CLC935-B8C part is an extended temperature range, high reliability version. Both parts are packaged in 40pin, 1.1 inch wide, ceramic DIPs with side-brazed leads for easy access and inspection.
