ZLNB2016

A Product Line of Diodes Incorporated www.DataSheet4U.com ZLNB2016 STANDARD DBS DUAL CHANNEL VOLTAGE AND TONE DETECTOR Summary The ZLNB2016 is a dual channel polarisation (voltage) and band select (tone) detector IC, primarily for satellite applications such as Low Noise Blocks (LNBs) and satellite distribution systems. An optimised design provides a low supply current and a wide operating voltage whilst increasing performance and reliability. The ZLNB2016 offers excellent interference rejection with minimal application cost and packaged in the 3x3mm QFN it provides a very small solution. Features NEW PRODUCT Two polarisation voltage detectors Two robust, interference tolerant 22kHz tone detection (without external signal filtering) “No Receiver” detect function for power saving and isolation control Low quiescent supply current, 2mA typical Wide operating supply voltage 3V to 8V Low external component count minimises application cost True and inverted outputs to support popular multiplexer ICs Pin Assignments BHOR1 HOR1 ENA1 FIN1 VPOL1 VPOL2 FIN2 BHOR2 HOR2 ENA2 GND VCC TD1 BTD1 BTD2 TD2 Top View Application Twin Universal LNBs Quad Universal LNBs Multi Output LNBs Satellite Multi-Switches Bottom View GND Twin Universal LNB System Diagram RF Gain Stages GaAs FET’s Down Conversion IF Gain IF Switching IF Gain, LNB Control & Power Mgt.
