AS44CC37x product family - Rev 1.0.0 – Sept 1
st 2009
Audio/Video RF Modulators
AS44CC37x
Overview
The
Abilis
AS44CC37x
RF
modulators
can
be
programmed through a high speed I2C interface to
support PAL, SECAM or NTSC standards. They are
designed for use in Set-Top Boxes and similar devices.
They
are
the
latest
generation
of the
legacy
MC44BS37x family of devices from Freescale and are
software
compatible,
providing
straightforward
transition for system upgrades.
The AS44CC37x devices are offered in an industry-
standard 16-pin SOIC RoHS-compliant package.
Applications
Set-Top Box, IPTV box
VCR, DVD players
Game consoles
Benefits
New generation of industry leading product
family, based on cost effective CMOS process.
Extremely low BoM :
o
Reduced board space
o
Simplified PCB layout and
manufacturing
o
Simplified sourcing
Shorter time to market :
o
Functional equivalent to industry
standard devices
o
Backward software compatibility with
legacy products
o
Available evaluation board and
reference design
