# 1. OCP Mezzanine Card Introduction

![The image displays a red triangular warning sign with a white border. Inside the triangle, centered, is a white exclamation mark.](.product-spec-ocp-4x10g-sfp-user-manual/9498a551b372dfb014434fe2d7edb7ee4d308b2c16cc90fafdc93723e868a71d.jpg)

Warning: This is an EA (early available) engineering manual. The contents may not accurately reflect the actual or final version of this product.

The original OCP Mezzanine Card for Intel v2.0 Motherboard specification1 have been developed mainly to serve the use case of Single and Dual port 10G Ethernet card. Adoption of this specification has been seen in OCP community on different server and storage platforms. Over the recent two years, demand of supporting new use cases were raised and the original Mezzanine card specification cannot support those new use cases without modification in order to support different I/O types, increase bandwidth of data and management, and support higher power controller IC. Mezzanine card 2.0 specification is developed based on original OCP Mezzanine card. It extends the card mechanical and electrical interface to enable new uses cases for Facebook and other users in OCP community. The extension takes backward compatibility to existing OCP platforms designed for original OCP Mezzanine card specification V0.5 into consideration, and some tradeoffs are made between backward compatibility and new requirements.

Mezzanine card with different placement height restriction, I/O connectors’ location, and mezzanine connector stacking height to baseboard. Type 1 is the original OCP Mezzanine 1.0 stack with 8mm stacking. This is also the most widely adopted stacking Type. The baseboard needs to have a cut out with in the I/O area since most network connector is taller than 8mm. Type 2 is based on Type 1, but change stacking to 12mm for taller heatsink. Baseboard and system does not have strict height constrain can take this stacking with the benefit to avoid have cut out in baseboard, and having taller heatsink on Mezzanine card side.

64 pin Connector C is added in Mezzanine card 2.0 Rev0.45. The pin assignment of Connector C has up to 4x KR, their low speed and I2C signals, and power pins. It is created to support the use case of KR only. Connector C can be used independently on Mezzanine card side. The typical KR Mezzanine card implementation with Connector C does not have Connector A and Connector B on card side.

# OCP card Ethernet KR/KX Interfaces

4x SFI Mezzanine card with Connector C and with 4 pcs SFP+ connectors.

Module’s Broadcom® Ethernet Controller BCM57502, connected to the SoC through PCIex8 lane

4x 10GBASE-KR and its sideband signals

Supports both full-duplex and half-duplex

Note: BCM57504 4x 25GBASE-KR only make sense if PHYs are on carrier board directly, not with OCP card, because OCP connectors cannot sustain 25G

# HALT tested

Thermal Stress, Vibration Stress, Thermal Shock and Combined Test

# EMI

EN55032 Class B inside an enclosure

Ultrasound equipment will typically be sensitive to noise in the 1MHz to 20MHz band, we shall handle it well during these bands

# De-rating

De-rating file is provided by RD (delta temperature of some of components is based on the experience of previous products) and reviewed/approved by RRC team before each Gerber Out

Once we have real sample on-hand, the temperature of critical components shall be measured and feedback to the De-rating file to see if it still in specification.

# MTBF

200,000 hrs commercial 40℃ ambient (according MIL calculation) based on actual calculated de-rating

120,000 hrs ETT -20℃\~70℃ ambient (according MIL calculation) based on actual calculated de-rating (excludes the BCM57504 LAN controller)

# Specific Requirement

PM need a table with early predicted MTBF (must with CPU/PCH into consideration) at 0℃ to +60℃ and -40℃to +85℃ for every SKUs on leading platform. We need this table to align which SKUs are suitable for ETT support

All the final version MTBF shall be calculated with real CPU/PCH data (for example, Intel has real reliability data, called F.I.T data)
- All the standard SKUs need has its own final version MTBF report, not just the highest-end SKU

heat sink height is limited to 7.5mm max and may not be able to provide sufficient cooling to some controller IC. Type 2 vertical stack allows 11.5mm max for heatsink and provide more freedom to thermal design. This implementation has limitation in system mechanical compatibility due to taking extra volume. Vendor may need to modify mechanical design in order to support it.
