APPLICATION INFORMATION (Cont’d)
Design Considerations
ESD Bypass
Pin 37 (ESD_BYP) is provided for an optional external ESD bypass capacitor only (i.e. 0.1
mF ceramic). It should not be
connected to any supply rail.
5V Overcurrent Output
Maximum Overcurrent Protection output drop at 55 mA on 5V_OUT is 100 mV. To meet HDMI output requirements of
4.8 5.3 V, an input of greater than 4.9 V should be used (i.e. 5.1 V
±4%). A 0.1 mF ceramic bypass capacitor on this output
is also recommended.
Hotplug Detect Input
To meet the requirements of HDMI CTS TID712, the following pullup/pulldown configuration is recommended for a 3.3 V
±10% internal VCC rail (See Figure 4 below). A 0.1 mF ceramic capacitor is recommended for additional edge debounce and
ESD bypass.
DUT On vs. DUT Off
Many HDMI CTS tests require a power off condition on the System Under Test. Many Dual Rail Clamp (DRC) ESD diode
configurations will be forward biased when their VDD rail is lower than the I/O pin bias, thereby exhibiting extremely high
apparent capacitance measurements, for example. The MediaGuard
t backdrive isolation circuitry limits this current to
<5
mA, and will help ensure compliance.
