8 Detailed Description

8.1 Overview

The TMUX136 device is a 2-channel, 2:1, switch specifically designed for the switching of high-speed signals in

handset and consumer applications, such as cell phones, tablets, and notebooks but may be used for any high

speed application. The wide bandwidth (6.1 GHz) of this switch allows signals to pass with minimum edge and

phase distortion. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the

outputs and will support both signle-ended and differential signals. The device also has a low power mode that

reduces the power consumption to 5 μA for portable applications with a battery or limited power budget.

The TMUX136 device integrates ESD protection cells on all pins, is available in a tiny UQFN package

(1.5 mm × 2 mm) and is characterized over the free-air temperature range from –40°C to +85°C.

8.3 Feature Description

8.3.1 Low Power Mode

The TMUX136 has a low power mode that reduces the power consumption to 5 μA while the device is not in use.

To put the device in low power mode and disable the switch, the bus-switch enable pin EN must be supplied with

a logic High signal.

8.4 Device Functional Modes

8.4.1 High Impedance Mode

The TMUX136 has a high impedance mode that places all the signal paths in a Hi-Z state while the device is not

in use. To put the device in high impedance mode and disable the switch, the bus-switch enable pin EN must be

supplied with a logic High signal as shown in Table 1.
