SUMMARY OF BENEFITS
• ^{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.
