AD9970BCPZ

The AD9970BCPZ from Analog Devices is a sophisticated CCD signal processor engineered for high-speed digital video camera systems. Operating at pixel rates up to 65 MHz, this device integrates a complete analog front-end, including correlated double sampling (CDS) with selectable gain, a 10-bit variable gain amplifier (VGA) offering 6 dB to 42 dB gain, and a 14-bit, 65 MSPS analog-to-digital converter (ADC).

A key feature is the Precision Timing core, which provides precise clock adjustments with 240 ps resolution at 65 MHz, crucial for accurate timing in imaging applications. The processor also includes on-chip 3 V drivers for horizontal and RG signals, and a reduced range LVDS interface for data output. Programming is handled via a simple 3-wire serial interface.

Designed for demanding applications, the AD9970BCPZ is suitable for professional HDTV camcorders, high-end digital cameras, broadcast cameras, industrial high-speed cameras, and high-speed data acquisition systems. It operates with a 1.8 V analog and digital core supply voltage and is specified for an operating temperature range of -25°C to +85°C.

The device is housed in a space-saving 5 mm × 5 mm, 32-lead LFCSP_VQ package, making it ideal for compact designs. The analog front-end incorporates black level clamping with variable level control, further enhancing image quality.
