Frequency setting resistor.
Internal bandgap voltage filter capacitor.
Most positive power supply connection.
DESCRIPTION
GS9035A
Data rate indication (Auto mode) or data rate select (Manual mode). TTL/CMOS compatible I/O. In
auto mode these pins can be left unconnected.
Serial clock output. SCO/SCO are differential current mode outputs and require external 75Ω
pullup resistors.
Serial data output. SDO/SDO are differential current mode outputs and require external 75Ω pullup
resistors.
Most positive power supply connection.
Clock enable. When HIGH, the serial clock outputs are enabled.
