L8200 Datasheet

CONFIDENTIAL, SUPPLIDE UNDE NDA SINGLE LNB-BIAS, CONTROL AND POWER MANAGEMENT SOLUTION 
 
 
 
 
DESCRIPTION
 
The UTC L8200 is a single chip power management and
control solution for LNB’s. The highly integrate solution provides
all the required FET and mixer bias, control detection and
decoding, local oscillator switching and a stable power supply for
the IF amplifier an additional support functions. in 20 pin
HTSSOP package, the UTC L8200 only requires 3 external
components providing a very small compact solution. Being at the
heart of the LNB monitoring the control, power management and
environmental conditions the UTC L8200 is able to provide
reliable solution eliminating effects such as false switching and
over loading.  
 
 
FEATURES
 
 
* Single chip LNB bias, control and power management
* Integrated regulated supply for LNB
* Zero Gate FET switching
* Voltage detection for polarization switching  
* 22kHz tone detector with signal rejection for band switching
* Programmable mixer and FET bias
