The ICS9169-01 generates all clocks required for high speed
RISC or CISC microprocessor systems such as 486, Pentium/
Pentium Pro™, PowerPC™, etc. Four different reference
frequency multiplying factors are externally selectable with
smooth frequency transitions. These multiplying factors can
be customized for specific applications. A test mode is provided
to drive all clocks directly.
High drive BCLK outputs typically provide greater than 1V/
ns slew rate into 30pF loads. PCLK outputs typically provide
better than 1V/ns slew rate into 20pF loads while maintaining
50±5% duty cycle. The REF clock outputs typically provide
better than 0.5V/ns slew rates.
