9UMS9001
Features/Benefits:
• Supports Dothan ULV CPUs with 100 and
133 MHz CPU outputs
• Dedicated TEST/SEL and TEST/MODE pins
saves isolation resistors on pins
• PCI_SRC and CPU STOP inputs for power
manangment
• Fully integrated Vreg
• Integrated series resistors on differential
outputs
• Supports split rail operation for maximum
power savings
• Also runs from single 3.3V rail
• 1.05V-3.3V support for differential VDDIO

DESCRIPTION
OUT Crystal output, nominally 14.318MHz.
IN Crystal input, Nominally 14.318MHz.
PWR Power pin for the REF output and crystal oscillator. 3.3V nominal.
OUT 3.3V 14.318MHz reference clock
I/O Data pin for SMBus circuitry, 5V tolerant.
IN Clock pin of SMBus circuitry, 5V tolerant.
IN
3.3V input that puts the part in test mode. This is a realtime input. See the Test Clarification Table for
details.
IN When Test mode is selected, this chooses either hi-Z or REF/N for the outputs.
IN 3.3V tolerant input that stops all PCI and SRC clocks, except those set to be free running.
PWR 3.3V power supply for the PCI outputs
OUT 3.3V PCI clock output.
OUT 3.3V PCI clock output.
OUT Free running 3.3V PCI clock output
PWR Ground for PCI output clocks.
PWR Ground for the USB clock.
OUT Fixed 3.3V 48MHz USB clock output
PWR 3.3V Power supply for the 48MHz output
PWR 3.3V Power supply for the 48/96MHz PLL
PWR Power supply for DOT96 output. VDD_IO = 1.05 to 3.3V +/-5%.
OUT
Complement side of low-power CK505-type 96MHz differential clock. Rs is integrated (No external
series resistor required).
OUT
True side of low-power CK505-type 96MHz differential clock. Rs is integrated (No external series
resistor required).
PWR Ground for 96MHz output
PWR Ground for LCD 100 MHz output.
OUT
Complement side of low-power CK505-type LCD100MHz spreading differential clock. Rs is integrated
