7335-PB01-R
The BCM7335 is Broadcom’s next-generation satellite PVR set-top box
system on a single chip in 65-nm process. It integrates the dual-tuner/
demodulator BCM4506 front-end technology and the latest generation
of AVC decoder that supports multiple video formats. The BCM7335
supports worldwide standards for DBS transmission systems based on
DVB-S2, 8PSK, and is backward compatible with the DVB-S standards.
The BCM7335 operates on a dual-threaded MIPS CPU core running at
450-MHz and yielding over 950 DMIPS in performance. The BCM7335
is designed to support UMA and non-UMA memory architectures,
utilizing a 400-MHz clock, 32 + 16-bit wide Double Data Rate (DDR2)
memory I/F for enhanced performance and allows cost-effective
memory solutions.
The BCM7335 is a true single chip that can decode transport streams
delivered via the integrated DBS front ends. In addition, it is capable of

decoding external TS input from 10/100 Ethernet port or via the dual
SATA interface for DVR applications with full trick mode support.
Several interfaces required for TV output are integrated on-chip
including the HDMI, baseband composite, component, or S-Video. An
RF channel 3/4 modulated output is also integrated on chip. An HD
video encoder with copy protection that supports NTSC, PAL, and
SECAM with simultaneous SD output and optional Macrovision/DCS
support is integrated on chip as well.
The BCM7335 incorporates Broadcom’s advanced 2D graphics engine,
offering true studio-quality text and graphics with extremely efficient
use of memory and bandwidth.
A full range of peripheral devices is supported on the BCM7335,
including UARTs, dual ISO7816 smart card interfaces, GPIO, counters/
timers, IR Tx/Rx, UHF Rx, I
