Description
The SKY13327-365LF is a four-input to two-output switch matrix
intended for Direct Broadcast Satellite (DBS) switching and cable
TV/modem applications. The SKY13327-365LF enables any of the
four inputs to either of the two outputs. Switch states can be
selected using tone and voltage signals together with vertical-
horizontal mirror control inputs. The load detection and Digital
Satellite Equipment Control (DiSEqC) rejection are integrated on
the switch.
The SKY13327-365LF 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 vertical-horizontal 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.
Another Skyworks switch, the SKY13369-365LF, can be used to
reverse the I1, I2, I3, and I4 truth Table logic.
The SKY13327-365LF is manufactured in a compact, 4 x 4 mm,
20-pin Quad Flat No-Lead (QFN) package.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION:
Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
