描述 Description

Please note: SKY13419-365LF is being discontinued and is not recommended for new designs. The SKY13419-365LF is a four-input to two-output switch matrixintended for Direct Broadcast Satellite (DBS) switching and cableTV/modem applications. The SKY13419-365LF enables any of thefour inputs to either of the two outputs. Switch states can beselected using tone and voltage signals together with verticalhorizontalmirror control inputs, and the logic control signal(LGCTL, pin 9).

The vertical/horizontal mirror control signal (OMR, pin 18) invertsthe logic for the I2 and I4 signals (pins 16 and 20, respectively),and for the I1 and I3 signals (pins 14 and 2, respectively). Thelogic control signal inverts the logic for the I1 and I2 signals, andfor the I3 and I4 signals.

Load detection and Digital Satellite Equipment Control (DiSEqC)rejection are integrated on the switch. The SKY13419-365LFrejects DiSEqC signals and responds only to continuous-tone andvoltage signals or vertical-horizontal mirror control inputs. Theswitch on/off states are not changed by DiSEqC signals, and onlychanged by continuous-tone and voltage signals or verticalhorizontalmirror control inputs.

One of the two switch outputs can be deactivated when no-toneand no-voltage are applied to one of the tone/voltage detectors.

The SKY13419-365LF is manufactured in a compact, 4 x 4 mm,20-pin Quad Flat No-Lead (QFN) package.
