OPERATION
S510067
FUNCTIONAL DIAGRAM
DESCRIPTION
The S510067 consists of an input Linear AGC amplifier and a
video/AGC amplifier. The amplifiers are designed to interface
directly with saw filters and A/D converters The AGC is delayed
between the two blocks for optimal NF and IM3 performance
across the full AGC range. The final stage is capable of
providing 2 V
PP
into a 500鈩?load. The part is offered in the
QFN28 & 20 TSSOP package and is RoHS compliant.
APPLICATIONS
聲 Digital Terrestrial Tuners 聲 Digital TV Sets.
聲 Digital Radios 聲 Digital Set top boxes.
