The differentialoutputsof the LNA can be• INTEGRATED LOW-PASS, ANTI-ALIASING switchedthroughthe 8x10 cross-pointswitch,whichBUTTERWORTH FILTER is programmable throughthe serialinterfaceinput– 14.5MHz BANDWIDTH port.

• INTEGRATED INPUT CLAMP DIODES The outputof the LNA isfed directlyintothe VGA
• DIFFERENTIAL OUTPUT stage. The VGA consists of two parts, a Voltage-ControlledAttenuator (VCA) and a• INTEGRATED INPUT LNA Programmable Gain Amplifier(PGA). The gain and• READABLE CONTROL REGISTERS gain range of the PGA can be digitallyconfigured• INTEGRATED CONTINUOUS WAVE (CW) separately.The gain of the PGA can vary between PROCESSOR four discretesettingsof 25dB, 30dB, 35dB, and 40dB. The VCA has fourprogrammable maximum attenuationsettings:29dB, 33dB, 36.5dB,and 40dB. Also,theVCA can be continuouslyvariedby a control voltagefrom 0dB to a maximum of 29dB, 33dB, 36.5dB,and 40dB. The output of the PGA feeds directlyinto an integratedlow-passfilter.

(2) Material type: When designated, preproduction parts are prototypes/experimental devices, and are not yet approved or released for full production. Testing and final process, including without limitation quality assurance, reliability performance testing, and/or process qualification, may not yet be complete, and this item is subject to further changes or possible discontinuation. If available for ordering, purchases will be subject to an additional waiver at checkout, and are intended for early internal evaluation purposes only. These items are sold without warranties of any kind. (3) RoHS values: Yes, No, RoHS Exempt. See the TI RoHS Statement for additional information and value definition. (4) Lead finish/Ball material: Parts may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width. (5) MSL rating/Peak reflow: The moisture sensitivity level ratings and peak solder (reflow) temperatures. In the event that a part has multiple moisture sensitivity ratings, only the lowest level per JEDEC standards is shown. Refer to the shipping label for the actual reflow temperature that will be used to mount the part to the printed circuit board. (6) Part marking: There may be an additional marking, which relates to the logo, the lot trace code information, or the environmental category of the part. Multiple part markings will be inside parentheses. Only one part marking contained in parentheses and separated by a "~" will appear on a part. If a line is indented then it is a continuation of the previous line and the two combined represent the entire part marking for that device.
