DESCRIPTION
I Most negative power supply connection.
I Timing control capacitor for internal system clock.
O Lock indication. When HIGH, the GS9035C is locked. LOCK is an open collector output and
requires an external 10k pullup resistor.
I SMPTE/Other rate select.
I Digital data input (Differential ECL/PECL).
I Most positive power supply connection.
I Auto or Manual mode select. TTL/CMOS compatible input.
I Loop filter component connection.
I Loop filter component connection.
I Loop filter component connection.
I R_VCO return.
I Frequency setting resistor.
I Internal bandgap voltage filter capacitor.
I Most positive power supply connection.
I Reserved Input. Always connect to GND
I/O 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.
O Serial clock output. SCO/SCO are differential current mode outputs and require external 75Ω
pullup resistors.
O Serial data output. SDO/SDO are differential current mode outputs and require external 75Ω pullup
resistors.
I Most positive power supply connection.
I Clock enable. When HIGH, the serial clock outputs are enabled.
