3.1 Highlights
Double-sided, 1.0 mm thickness FR4 PCB is used for the half NIM design.
The core of the half NIM is the one-chip MOPLL IC TUA 6039-2, which works from 3.3V~5V.
The following are some of the outstanding features:
Advancement and New Features of TUA6039-2:
• Loop-Thru Function Simplifies Alignment and Production Process
• RF AGC Switch Simplifies the Adoption of External RF AGC Voltage
• Crystal Buffer Allows Direct Connection to a Baseband with 4MHz Xtal Input
• NPN port P4 can also be used as ADC input
There would be no longer external damping resistors which is necessary to disable the IF filter
so as to test the RF filter performance and characteristics
There would be no longer Jumpers to select internal or external RF AGC. Simply select via IIC
RF AGC Buffer Reduces Impact from MOSFET to Tuner IC
performance of the Tuner
With RF AGC Buffer, RF AGC voltage can be measured without disturbing the RF AGC
