Function
Provides power to the hook switch LED. Voltage is usually +5V
(for 8mA LED current), but can be higher if an external resistor
is placed in series with the internal 470 resistor.

2 Manufacturing Information
2.1 Handling and Assembly Recommendations
The CYG2100 is not hermetically sealed, and should not be exposed to any liquid-based rinsing processes. IXYS
Integrated Circuits Division recommends two (2) approaches: (1) the modem should be installed in a wave-soldering
process that uses a no-clean soldering flux that will mostly evaporate during the normal wave-soldering processes,
(2) the modem should be soldered in by hand after the rest of the card is wave-soldered.
2.2 Reflow Profile
This product has a maximum solder temperature as shown below.
