Description
A Clock Select 0. Selects outputs on CLKA1 and CLKA2 per table on page 2.
Crystal connection. Connect to a crystal or leave unconnected for a clock input.
Crystal connection. Connect to a fundamental crystal or clock input.
Connect to +3.3 V or +5 V. Must be same as other VDD.
A Clock Select 1. Selects outputs on CLKA1 and CLKA2 per table on page 2.
Connect to ground.
Clock C output 1. Depends on setting of CCS per table on page 2.
Clock C output 2. Depends on setting of CCS per table on page 2. Same as CLKC1.
Clock B output 2. Depends on setting of BCS1, 0 per table on page 2.
Clock B output 1. Depends on setting of BCS1, 0 per table on page 2.
Clock C Select pin. Selects outputs on CLKC1 and CLKC2 per table on page 2.
Don't Connect. Do not connect anything to this pin.
Clock A output 2. Depends on setting of ACS1, 0 per table on page 2.
Connect to ground.
Output Enable. Tri-states all outputs when low.
Connect to +3.3 V or +5 V. Must be same as other VDD.
Clock A output 1. Depends on setting of ACS1, 0 per table on page 2.
Buffered Reference clock Output. Same frequency as crystal or clock input.
B Clock Select 0. Selects outputs on CLKB1 and CLKB2 per table on page 2.
B Clock Select 1. Selects outputs on CLKB1 and CLKB2 per table on page 2.
Key: TI = tri-level input; XI, XO = crystal connections; I = Input with internal pull-up resistor;
O = Output; P = power supply connection
