8283 - LNB SUPPLY AND CONTROL-VOLTAGE REGULATOR

Datasheet Summary

Description

The ENT (Tone Enable) terminal activates the internal tone signal, modulating the dc output with a ±0.3 V, 22 kHz symmetrical waveform.

The internal oscillator is factory-trimmed to provide a tone of 22 kHz ±2 kHz.

No further adjustment is required.

8283 PRELIMINARY INFORMATION (Subject to change without notice) November 21, 2000 LNB SUPPLY AND CONTROL-VOLTAGE REGULATOR Intended for analog and digital satellite receivers, the low-noise block converter regulator (LNBR) is a monolithic linear and switching voltage regulator designed to provide power and interface signals to the LNB down converter via the coaxial cable. If the device is in stand-by mode (EN terminal LOW), the regulator output is disabled, allowing the antenna downconverters to be supplied or controlled by other satellite receivers sharing the same coaxial cable. Similar two-output LNB supply and control voltage regulators are the A8284SB/SLB.
