VHDCI Carrier Overview

This carrier is an adapter to allow 8 EEM to be driven from 2 VDHCI connectors.

ARTIQ PCBs with VHDCI

KC705 and FMC-DIO-32ch-LVDS-a plus a VHDCI cable (no integrated termination).
PCB_Metlino serves as the ARTIQ Core Device in uTCA crates. Metlino has a pair of VHDCI connectors on its front panel that are driven directly by the Metlino FPGA (low latency).
PCB_Sayma_AMC has an LPC FMC connector and can control four EEMs via FMC-DIO-32ch-LVDS-a, a VHDCI cable and VHDCI-Carrier.

VHDCI Carrier Specification

The design files are located here. This carrier is compatible with Sinara EEM peripherals.

Front panel connections:

Two VHDCI connectors, each routed to 4 extension headers.
I2C from each VHDCI routed to TCA9548 8-ch multiplexer - one channel to each of the 4 extension headers and one to and EEPROM

Rear connections:

EEM Carriers require a +12 V supply (60 W); power barrel connector is 2.50 mm ID (0.098"), 5.50 mm OD (0.217") (p/n CUI PJ-102BH), positive potential on center conductor. The same type of connector is installed on front and rear side.
The 96 pin DIN connector can be mounted optionally to supply 12V.

Internal connections:

8 IDC connectors for EEM
