L8312
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.
