MITEL VP216ACGHP1S Datasheet

Dual 90MHz 6-Bit Analog to Digital Converter with VCO

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.

FEATURES

■ 90MHz Conversion Rate

■ VCO or Ext. Clock Interface

■ High Bandwidth ADC Driver Ampliﬁer

■ Internal ADC Reference

■ TTL Data Outputs

■ Single 5 Volt Supply

■ Dual ADC System for good channel matching

APPLICATIONS

■ Satellite Decoders

■ Multimedia

■ Communications
