QPI-10-CB1 carrier board featuring
the QPI-10LZ EMI filter with
integrated Hot-Swap
Introduction
QPI-10LZ Product Description
The QPI-10-CB1 carrier board is an evaluation
board platform designed to demonstrate the EMI
and Hot-Swap capabilities of a QPI-10LZ filter, with
any combination of 48V input PRM / VTM and BCM
evaluation boards. The QPI-10-CB1 board includes a
pre-mounted filter along with some additional
components necessary to demonstrate the full
functionality of the filter, along with mounting areas
The QPI-10LZ integrates a complete 48 V Hot-Swap function
with an EMI filter to achieve a high performance, high
•
density solution for V I Chip applications, while minimizing
overall design time and effort. The product aligns with the
AdvancedTCATM PICMG3.0 requirements for hot insertion
and board level conducted noise limitations. The EMI filter
provides conducted common-mode (CM) and differential-
mode (DM) noise attenuation from 150 kHz to 30 MHz.
The QPI-10LZ is designed for use on a 48 or 60 Vdc bus
(36 – 76 Vdc). The inrush current limit and circuit breaker
are designed to satisfy the 200 W per board PICMG3.0‚
limit up to 70°C PCB temperature around the QPI-10LZ.

provides basic instructions for assembly and use of the
board. Further information on the functionality of the

The under and overvoltage thresholds can be trimmed
separately via the UVEN and OV inputs using external
series resistors. The QPI-10LZ provides two POWER GOOD
signals, with one referenced to the input ground and the
other to the output ground, which can be used to enable
