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 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 VPP into a 500Ω load. The part is offered in the QFN28 & 20 TSSOP package and is RoHS compliant. APPLICATIONS • Digital Terrestrial Tuners • Digital TV Sets. • Digital Radios • Digital Set top boxes.
