applies to the ADV7280-M only.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
These devices are high performance integrated circuits with
an ESD rating of <2 kV, and they are ESD sensitive. Proper
precautions must be taken for handling and assembly.
THERMAL RESISTANCE
The thermal resistance values in Table 8 are specified for the
device soldered onto a 4-layer printed circuit board (PCB) with
a common ground plane and with the exposed pad of the device
connected to DGND. The values in Table 8 are maximum values.

REFLOW SOLDER
The ADV7280/ADV7280-M are Pb-free, environmentally
friendly products. They are manufactured using the most up-to-
date materials and processes. The coating on the leads of each
device is 100% pure Sn electroplate. The devices are suitable for
Pb-free applications and can withstand surface-mount soldering
at up to 255°C (±5°C).
In addition, the ADV7280/ADV7280-M are backward-
compatible with conventional SnPb soldering processes. This
means that the electroplated Sn coating can be soldered with
Sn/Pb solder pastes at conventional reflow temperatures of
220°C to 235°C.

14 XTALP Output
Connect this pin to the external 28.63636 MHz crystal, or leave it unconnected if an external
1.8 V, 28.63636 MHz clock oscillator source is used to clock the ADV7280. The crystal used
with the ADV7280 must be a fundamental crystal.
15 XTALN Input
Input Pin for the External 28.63636 MHz Crystal. The crystal used with the ADV7280 must
be a fundamental crystal. If an external 1.8 V, 28.63636 MHz clock oscillator source is used
to clock the ADV7280, the output of the oscillator is fed into the XTALN pin.

26 ALSB Input
This pin selects the I
