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 sig-

nal, 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 sub-

strate. 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 tempera-

ture range, while the CLC935-B8C part is an extended tempera-

ture range, high reliability version. Both parts are packaged in 40-

pin, 1.1 inch wide, ceramic DIPs with side-brazed leads for easy

access and inspection.
