SPT7852 : The SPT7852 has two 10-Bit CMOS analog-to-digital converters that can sample data at speeds up to 20 MSPS. It has excellent low noise performance with a very low typical power dissipation of only 160 mW—that’s the total power for both converters. The SPT7852 uses a dual configuration of the proprietary circuit design found in our 10-bit CMOS single converter family, to achieve its high performance in a CMOS process. The SPT7852 is specifically designed for video decoding applications and is ideal for S-video decoding and decoding of multiple composite video sources. It also has excellent application in the area of coherent I/Q demodulation in such applications as QAM demodulation and TV set-.
SPT7853 : The SPT7853 has three 10-bit analog-to-digital converters on one CMOS chip, each with a sample rate of 30 MSPS. This device is ideal for professional-level video decoding to 4:2:2/4:4:4 CCIR-601 standard specifications for component digital video, including YCrCb and RGB decoding, professional video equipment, video frame grabbers, medical imaging, flat panel display and projection applications. The SPT7853 offers significant advantages over discrete single-channel A/D implementations. Board area, package count, system cost and power dissipation can greatly be reduced by using a single SPT7853 device. In addition, several performance advantages exist, including low channel-to-channel cross-t.
SPT7855 : The SPT7855 is a 10-bit monolithic, low-cost, ultralowpower analog-to-digital converter capable of minimum word rates of 25 MSPS. The on-chip track-and-hold function assures very good dynamic performance without the need for external components. The input drive requirements are minimized due to the SPT7855’s low input capacitance of only 5 pF. Power dissipation is extremely low at only 135 mW typical at 25 MSPS with a power supply of +5.0 V. The digital outputs are +3 V or +5 V, and are user selectable. The SPT7855 is pin-compatible with an entire family of 10-bit, CMOS converters (SPT7835/40/50/55/60/61), which simplifies upgrades. The SPT7855 has incorporated proprietary circuit design* a.
