Crystal input, Nominally 14.318MHz.
Data pin for SMBus circuitry, 5V tolerant.
Clock pin of SMBus circuitry, 5V tolerant.
3.3V input that puts the part in test mode. This is a realtime input. See the Test Clarification Table for
details.
When Test mode is selected, this chooses either hi-Z or REF/N for the outputs.
3.3V tolerant input that stops all PCI and SRC clocks, except those set to be free running.
Complement side of low-power CK505-type 96MHz differential clock. Rs is integrated (No external
series resistor required).
True side of low-power CK505-type 96MHz differential clock. Rs is integrated (No external series
resistor required).
Complement side of low-power CK505-type LCD100MHz spreading differential clock. Rs is integrated
(No external series resistor required).
True side of low-power CK505-type LCD100MHz spreading differential clock. Rs is integrated (No
external series resistor required).
Clock request input for SRC output pair 1. See the SRC, LCD, DOT Power Management Table for
details
Fixed 3.3V 48MHz USB clock output
