description

The TLC976 is a multichip module (MCM) subsystem designed for interfacing Charge-Coupled Device (CCD)

in camcorder and digital camera systems. The TLC976 includes correlated double sampler (CDS), automatic

gain control (AGC), black level clamp circuit, 10 bit, 20 MSPS analog-to-digital converter (ADC), and internal

reference voltage generator for ADC.

The CDS/AGC can be connected directly to the ADC input or a separate signal can be connected directly to

the ADC input. A power-down mode is provided.

Assembled using the MCM process, the TLC976 provides isolation between the noisy digital domain and the

noise sensitive analog signals. The CDS/PGA, black level clamps are on one die and the ADC is on a separate

die. The separate dies significantly reduce the substrate noise to the analog section.

The TLC976 comes in a 56-pin TSSOP package with 0,50 mm pin pitch. This is about 25% smaller than using

two separate 32-pin quad flat packs (QFP).
