Datasheet Volume One of Two
Electrical Specifications
Clock multiplying within the processor is provided by the internal phase locked loop 
(PLL), which requires a constant frequency BCLK{0/1}_DP, BCLK{0/1}_DN input, with 
exceptions for spread spectrum clocking. DC specifications for the BCLK{0/1}_DP, 
BCLK{0/1}_DN inputs are provided in Table  7 -1 7 . These specifications must be met 
while also meeting the associated signal quality specifications outlined in Section 7.9.
7.1.6.1 PLL Power Supply
An on-die PLL filter solution is implemented on the processor. Refer to Tabl e  7 - 1 1 for 
DC specifications.
7.1.7 JTAG and Test Access Port (TAP) Signals
Due to the voltage levels supported by other components in the JTAG and Test Access 
Port (TAP) logic, Intel recommends the processor be first in the TAP chain, followed by 
any other components within the system. Please refer to the 
Intel® Xeon® Processor 
E5-1600 v2/E5-2600 v2 Product Families – Boundary Scan Description Language 
(BSDL) File for more details. A translation buffer should be used to connect to the rest 
of the chain unless one of the other components is capable of accepting an input of the  
voltage. Two copies of each signal may be required with each driving a different voltage 
level. 
7.1.8 Processor Sideband Signals
The processor include asynchronous sideband signals that provide asynchronous input, 
output or I/O signals between the processor and the platform or Platform Controller 
Hub. Details can be found in Table 7-5. 
All Processor Asynchronous Sideband input signals are required to be 
asserted/deasserted for a defined number of BCLKs in order for the processor to 
recognize the proper signal state. Refer to Section 7.9 for applicable signal integrity 
specifications.
7.1.9 Power, Ground and Sense Signals
Processors also include various other signals including power/ground and sense points. 
Details can be found in Tab l e  7 -5 .
