GENERAL DESCRIPTION\nThe TDA8705A is a 6-bit high-speed dual analog-to-digital converter (ADC) for satellite video and other applications. It converts the two analog input signals into two 6-bit binary-coded digital words at a maximum sampling rate of 80 MHz. All digital inputs and outputs are TTL compatible, although a low-level sine wave clock input signal is allowed.FEATURES\n• 2 times 6-bit resolution\n• Sampling rate up to 80 MHz\n• High signal-to-noise ratio over a large analog input frequency range (5.5 effective bits at 20 MHz full-scale input at fclk = 80 MHz)\n• TTL output\n• Two separated inputs (AC-coupling)\n• TTL compatible digital inputs\n• Low-level AC clock input signal allowed\n• Internal reference voltage regulator\n   (external reference regulation possible)\n• Power dissipation only 250 mW (typical)\n• Low analog input capacitance, no buffer amplifier required\n• No sample-and-hold circuit required.APPLICATIONS\nHigh-speed analog-to-digital conversion for:\n• DBS (Digital Broadcast Satellite)\n• QPSK (Quadrature Phase Shift Keying) demodulation\n• Video.
