MAX14979E
High-Bandwidth, ±15kV ESD Protection
LVDS Switch
7
Detailed Description
The MAX14979E is a high-speed analog switch targeted
at LVDS and other low-voltage switching up to 600MHz.
In a typical application, the MAX14979E switches two
sets of LVDS sources to a laptop LVDS panel. For extra
security, the MAX14979E is protected against Q15kV
ESD shocks. See the Functional Diagram.
With its low resistance and capacitance, as well as high-
ESD protection, the MAX14979E can be used to switch
most low-voltage differential signals, such as LVDS and
LVPECL, as long as the signals do not exceed the maxi-
mum ratings of the device.
The MAX14979E switches provide low capacitance and
on-resistance to meet low insertion loss and return-loss
specifications. The MAX14979E has three additional
AUX switches.
Digital Control Inputs
The MAX14979E provides a single digital control SEL.
SEL controls the switches as well as the AUX switches,
as shown in Table 1.
Analog-Signal Levels
The on-resistance of the MAX14979E is very low and
stable as the analog input signals are swept from ground
to V+ (see the Typical Operating Characteristics). The
switches are bidirectional, allowing COM_ _ and NC_ _/
NO_ _ to be configured as either inputs or outputs.
ESD Protection
The MAX14979E is characterized using the HBM for
Q
15kV of ESD protection. Figure 5 shows the HBM. This
model consists of a 100pF capacitor charged to the ESD
voltage of interest, which is then discharged into the test
device through a 1.5kI resistor. All signal and control
pins are ESD protected to Q15kV HBM.
