1 – Column Field Definitions:
Input / Output type and Voltage: Required output type with specified swing level (e.g. 1.8V LVCMOS, 2.5V LVCMOS, 3.3V LVCMOS, HCSL/PCIe, etc.).
Spread: If spread spectrum EMI reduction is required, list all desired spread options (e.g. -0.5%, +/-0.25%, -1%, +/-0.5%).
CCJ: The cycle to cycle jitter requirements for 10,000 clock periods CCJ = Absval(+/-CCJ). (list Max and NOTE THE UNITS (s / ns / ps).
FTOL: Frequency tolerance at 25C requirement excluding crystal error (total allowable output error (ppm) - crystal spec (ppm)) (e.g. (+/-50) – (+/-30) = +/-20).
FACC: Frequency accuracy across temp requirement excluding crystal error (total allowable output error (ppm) - crystal spec (ppm)) (e.g. (+/-50) – (+/-30) = +/-20).
VDD Typ: Typical power supply spec for this output. Generally this is the same for all outputs unless some are running on separate VDD planes.
Other Key Parameters/Comments: List any of the following if applicable:
1. LTJ/Dly/Acq
a. LTJ: Long Term Jitter requirements (e.g., 800pS) [LTJ = max – min, of accumulated jitter].
b. Dly: Time delay setting for measurement (e.g., 10s).
c. Acq: Number of acquisitions to be measured (e.g., 1000).
2. Duty Cycle: The duty cycle limits (e.g. 45%-55%).
3. Tr/Tf: Rise and fall times measured at 20%-80% of VDD, specify whether min, max or typ.
4. CL: For output clocks this is the total load capacitance driven by the output and includes estimated trace capacitance and the receiver input capacitance. If the I/O signal is Xin/Xout,
then CL refers to the load capacitance of the crystal taken from the crystal datasheet.
5. VCXO: If applicable, enter desired pull range and crystal parameter C0/C1 (to determine if crystal is pull-able).
