DESCRIPTION
Ground pin.
Complement clock of differential SRC clock pair.
True clock of differential SRC clock pair.
Complement clock of differential SRC clock pair.
True clock of differential SRC clock pair.
Supply for SRC clocks, 3.3V nominal
Complimentary clock of CPU_ITP/SRC differential pair
CPU_ITP/SRC output. These are current mode outputs.
External resistors are required for voltage bias. Selected by
ITP_EN input.
True clock of CPU_ITP/SRC differential pair CPU_ITP/SRC
output. These are current mode outputs. External resistors are
required for voltage bias. Selected by ITP_EN input.
3.3V power for the PLL core.
Ground pin for the PLL core.
This pin establishes the reference current for the differential
current-mode output pairs. This pin requires a fixed precision
resistor tied to ground in order to establish the appropriate
current. 475 ohms is the standard value.
Complimentary clock of differential pair CPU outputs. These are
current mode outputs. External resistors are required for voltage
bias.
True clock of differential pair CPU outputs. These are current
mode outputs. External resistors are required for voltage bias.
Supply for CPU clocks, 3.3V nominal
Complimentary clock of differential pair CPU outputs. These are
current mode outputs. External resistors are required for voltage
bias.
True clock of differential pair CPU outputs. These are current
mode outputs. External resistors are required for voltage bias.
Ground pin.
Clock pin of SMBus circuitry, 5V tolerant.
Data pin for SMBus circuitry, 5V tolerant.
Ref, XTAL power supply, nominal 3.3V
Crystal output, Nominally 14.318MHz
Crystal input, Nominally 14.318MHz.
Ground pin.
Reference Clock output
3.3V tolerant input for CPU frequency selection. Low voltage
threshold inputs, see input electrical characteristics for Vil_FS
and Vih_FS values.
TEST_Sel: 3-level latched input to enable test mode.
Refer to Test Clarification Table
