PDI Communications' PDI-60APD is a professional quality, user friendly, SAW filtered, High Definition TV signal processor designed primarily to feed 8VSB digital broadcast signals through a cable system to television receivers or interface converters able to decode the signal. Rock solid PLL controlled tuning by advanced microprocessor insures precise UHF, VHF or CATV channel access. Careful design of the input achieves a wide dynamic range and very low noise figure. Input tuning covers the range of 54 to 860 MHz. The agile output ranges from 54 to 860MHz and is controlled by another PLL circuit with 12.5 or 25 kHz offsets. Both the input and output channels have non-volatile memories that restore the channels automatically in the event of a power failure. SAW filtering guarantees broadcast quality pictures. An external IF loop is available on the rear of the unit enabling the processor to serve as a digital up converter in high speed internet CMTS and other digital systems. $995.00
