Overview
UNISONIC TECHNOLOGIES CO.
, LTD L8312 Preliminary LINEAR INTEGRATED CIRCUIT DUAL POLARIZATION AND TONE SWITCH CONTROLLER  DESCRIPTION The UTC L8312 is specially designed integrated circuit for control satellite receiver front-end block switch and provides customers with dual independent channel of two-control signal: polarization and tone switch controller for LNB switch signal path selection.
The UTC L8312 is characterized by its two independent channels and each provides logical outputs to show status of LNB switch polarization selection and 22 KHz tone signal.
Minimum number of external discrete components and the wide range of supply voltage make this device suitable in Twin, Quad and multiple feed universal LNB switch to get lower cost and minimum PCB size.
In order to satisfy the special LNB switch model, a tighter specification has been taken into consideration for the polarization switch characteristics.
The number of external components is also reduced.
The UTC L8312 includes separate 22K tone detection for each channel.
In addition, the built-in tone amplifier circuit is designed to protect transient signal by an external resistor and capacitor simply, and it also provides good bandwidth and sensitivity.
The UTC L8312 is generally applied in multi output LNB and multi switch.
