SPT7853

SPT7853 TRIPLE 10-BIT, 30 MSPS A/D CONVERTER FEATURES Three 10-bit, 30 MSPS ADCs on one chip SINAD of 54.5 dB @ ƒIN = 3.58 MHz Channel-to-channel cross talk: –66 dB typical Channel-to-channel gain matching of <0.1 dB Single 2X sample rate clock Total power dissipation: 580 mW (typical) Tri-state +3 V to +5 V digital outputs CMOS-compatible Single +5 V power supply APPLICATIONS CCIR-601 (4:2:2/4:4:4) digital component video RGB video decoding Medical imaging Flat panel displays PC projectors GENERAL DESCRIPTION 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-talk noise and well matched channelto-channel gain specifications. The three analog-to-digital converters are driven from a common 2X sample rate CMOS clock. The SPT7853 typically consumes only 580 mW of total power from a single +5 V supply. Digital output...
