S510067
DTV IF AGC AMPLIFIER
FEATURES
• SINGLE 3.3 V SUPPLY OPERATION
• Low DISTORTION: -55dBC@1VPP
• 14-68 dB TOTAL VOLTAGE GAIN
• 54 dB TOTAL GAIN CONTROL RANGE
• 10-100 MHZ OPERATION
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 VPP into a 500Ω load. The part is offered in the
QFN28 & 20 TSSOP package and is RoHS compliant.
