DEVICE DESCRIPTION
The ZLNB200X dual polarisation and tone switch controller is one of a wide range of satellite receiver LNB support circuits available from Zetex. It features two completely independent channels, each providing logic outputs to control LNB polarisation selection, local oscillator selection and downfeed disable. It is intended for use in Twin Universal LNBs, replacing many discrete components to save both manufacturing cost and PCB size whilst improving reliability.
The two polarisation control inputs of the ZLNB200X have a nominal threshold of 14.75V. The threshold is temperature compensated to minimise drift. Each features a low and stable input current that enables transient protection to be achieved with the addition of only a single resistor per channel.
FEATURES
• Dual polarisation switch
• Temperature compensated polarisation switch threshold
• Transient resistant inputs
• Includes Receiver-Off detector
• Dual tone switch
• User adjustable filter centre frequency and bandwidth
• User adjustable tone switching delays (ZLNB2003/4 only)
• Tone and pol. outputs TTL, CMOS, Pin diode and IF amp capable
• Receiver-Off detector TTL and CMOS compatible
• Wide supply operating range
• Low quiescent current
• Few external components
• Eliminates many discrete components
APPLICATIONS
• Twin Universal LNB
• Twin Universal IF switch boxes
• LNB switch boxes
