VP216
Dual 90MHz 6-Bit Analog to Digital Converter with VCO
Preliminary Information
DS4070 - 1.6 May 1996
The VP216 is a dual 90MHz 6-bit Analog to Digital
Converter designed for use in consumer satellite receivers
and
decoders,
video
systems,
multimedia
and
communications applications.
Operating from a single +5V supply, the VP216 includes
an on-chip high bandwidth ADC driver amplifier, a 6-bit ADC,
VCO or Ext. clock interface.
The VP216 also has the
necessary bias voltages for the reference resistor chain in
the 'flash' architecture of the ADC.
