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.
