SPT7853
TRIPLE 10-BIT, 30 MSPS A/D CONVERTER
BLOCK DIAGRAM
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 compo-
nent digital video, including YCrCb and RGB decoding, pro-
fessional 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 chan-
nel-to-channel cross-talk noise and well matched channel-
to-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 outputs can operate
with +3 V or +5 V logic and are tri-state capable. The
SPT7853 is offered in a small 52-pin thin quad flat pack
(TQFP) package and operates over the 0 to +70
°
C com-
mercial temperature range.
