Design Considerations
Introduction
The PIM300X module is designed to support the
Advanced Telecommunications Computing
Architecture (ATCA) power entry distribution
requirements for the Front Board / Blade per the
PICMG 3.0 specifications.
The PICMG 3.0 specification defines the Mechanical,
Shelf Management Interface, Power Distribution,
Thermal, Data I/O and Regulatory requirements for
the next generation of modular telecom architecture
platform for use in Central Office telecom
environments.
Input Pin Connections
The ATCA board is specified to accept up to a
maximum of 300W of input power via dual, redundant
-48Vdc Feeds through the Zone 1 (Power and
Management) connector, designated P10.
The power connector provides board to backplane
engagement via pins of varying lengths. Please
consult the PICMG 3.0 specifications for details.
The following are the design considerations of the
input pin connections of the PIM300X to the ATCA
power connector.
Pin
* Optional
The first pins to mate in the ATCA power connector
are the EARLY_A, EARLY_B, the two grounds
(LOGIC_GND, SHELF_GND) and the two returns
(VRTN_A, VRTN_B); followed by staggered
connections of -48V_A and -48V_B power Feeds. The
last pins to engage are the two short pins, ENABLE_A

& ENABLE_B. The ATCA backplane connects the
ENABLE_A to VRTN_A, ENABLE_B to VRTN_B,
EARLY_A to -48V_A and EARLY_B to -48V_B.
Optional EARLY_A & EARLY_B Connections:
During hot insertion of the ATCA board, the Inrush
Control circuit limits the surge current to the C_FLTR
capacitor. However, due to the presence of internal
EMI filter capacitance (located before the Inrush
Control circuit), there is a possibility of a surge current
that results in a voltage sag for 5 to 10 microseconds.
In most cases this should not be of concern because
all the ATCA Boards and FRU’s on the -48V bus
should be able to ride thru a 5msec/0Volt transient
event per the PICMG 3.0 specifications. In case this is
undesirable, it is recommended that Precharge
resistors, R1 & R2 (15 Ohms, with high surge
capability) should be connected as shown in the
Typical Application circuit.
Output Pin Connections
The out pin connections of the PIM300X to the
system board is described below:
Notes:
(1) -48V Main Output Bus:
(Signal Names: -48V_OUT & VRTN_OUT)
This is the main -48V output bus that provides the
payload power to the downstream (one or more)
DC/DC converters. The PIM300X module does not
regulate or provide isolation from the input -48V A/B
feeds.
48V A/B Feeds OR’ing, inrush protection for hot swap
capability and EMI filtering to attenuate the noise
generated by the downstream DC/DC converters.
