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.

necessary bias voltages for the reference resistor chain in

the 'ﬂash' architecture of the ADC.

The VP216 also has the
