The SKY13419-365LF is a four-input to two-output switch matrix intended for Direct Broadcast Satellite (DBS) switching and cable TV/modem applications. The SKY13419-365LF enables any of the four inputs to either of the two outputs. Switch states can be selected using tone and voltage signals together with verticalhorizontal mirror control inputs, and the logic control signal (LGCTL, pin 9).

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

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

One of the two switch outputs can be deactivated when no-tone and 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.
