The CX2416x family offers dual MPEG-2 MP@ML video decoders, 32-bit RISC
The CX2416x also features an impressive array of I/O features, including
CX2416x
electronics of dual-TV digital set-top box (STB) for satellite, cable, or terrestrial
encoders, and a set of peripheral I/O ports for STB front and back panel
engines for encryption of data to the HDD. This functionality enables

Conexant’s portfolio includes a comprehensive suite of semiconductor solutions
for broadband communications and the digital home. Conexant’s dual
MPEG-2 Standard Definition Television (SDTV) decoder IC features all the
major subsystems required to implement the core system and decoder
CPU, 2D graphics accelerator, dual video graphics display controllers, dual TV
connectors. The multi-format audio decoder supports MPEG-1, MPEG-2, and
Dolby
integrated NTSC channel 3/4 RF modulator and BTSC stereo encoder for
distribution of composite video and full MTS stereo sound to a remote room
in the house.
Personal video recorder (PVR) functionality is supported by three dual-stream
transport processors (up to 8 baseband transport stream (TS) interfaces),
fully integrated parallel- and serial-advanced technology attachment (ATA)
interfaces for hard disk drive (HDD) connectivity, and 3DES/AES ciphering
consumers to simultaneously watch and record separate programs, or record
a program while watching one previously recorded. NDS XTV
technologies are integrated in the IC.
dual USB2.0 host controllers, PCI bus interface, and HomePlug
via a high-speed UART.
For a complete four tuner, dual TV PVR system design, the only additional
components required are tuners, demodulators, modem codec, audio DACs,
DDR SDRAM, and flash memory ICs. This high level of integration enables a
low-cost system bill of materials and allows the flexibility of supporting
different modulation and compression technologies with a low-cost, high-
performance STB back end solution. Combining the CX2416x with the
Conexant CX24128 dual stream satellite tuner and CX24130 dual QPSK
demodulator provides a cost-effective satellite STB system solution for high-
performance, multi-tuner, dual-TV PVR services.
