Applications
The HI1179 is an 8-bit CMOS analog-to-digital converter for
video use that features a sync clamp function. The adoption
of a 2-step parallel method realizes low power consumption
and a maximum conversion speed of 35 MSPS, allowing up
to 8x over sampling of NTSC and PAL signals.
The HI1179 is available in the Industrial temperature range
and is supplied in 32 lead Plastic Metric Quad Flatpack
(MQFP) package. For lower sampling rates, refer to the
HI1176 data sheet.
