•
Full equalizer architecture spans -6 to +40 msec delays.
•
Automatic NTSC co-channel rejection filter provides
performance superior to traditional designs.
•
Full 496-tap equalizer implementation eliminates
multipath effects over a wide dynamic range.
•
Direct IF sampling architecture reduces system cost.
•
Digital adjacent channel filters provide additional
rejection for challenging environmental conditions.
•
On-chip digital PLL simplifies circuit design.
•
Integrated microcontroller with on-chip ROM for
simplified software development, intelligent monitoring
and fast-channel acquisition.
•
Operates at 15 dB SNR threshold of visibility.
•
Multiple AGC loops handle wide dynamic range input
and rapid signal fading.
•
Integrated AGC and 10-bit A/D converter for direct
interface to standard DTV tuners.
•
MPEG-2 transport interface requires no glue logic to
interface to the BCM7020 video and graphics subsystem,
smart cards and PCMCIA conditional access devices.
•
Support for both QAM and VSB for cable TV ready
systems at no additional cost.
