Design Checklist
Design Item | Carrier / Pod | Specification Reference |
---|---|---|
I/O pins are populated accordingly (lower ordinal before higher ordinal). | Both | 2. Pinouts and Signal Descriptions |
On a standard port, signals capable of differential I/O must be connected before signals which are single-ended only. | Both | 2. Pinouts and Signal Descriptions |
On a standard port, differential I/O are limited to pins 5-20. | Both | 2. Pinouts and Signal Descriptions |
On a standard port, differential I/O must be populated with the positive (P) pin of the pair on the lower ordinal I/O. | Both | 2. Pinouts and Signal Descriptions |
The pod and carrier include the required mounting holes. | Both | 3. Mechanical 3.2. Standard Port Dimensions (Carrier) 3.4. Transceiver Port Dimensions (Carrier) |
Pods and carriers use the specified Samtec connectors. | Both | 3.1. Connectors |
Pods and carriers use the recommended connector placement. | Both | 3.2. Standard Port Dimensions (Carrier) 3.4. Transceiver Port Dimensions (Carrier) |
The carrier includes a SmartVIO controller. | Carrier | 1.4.2. Carrier |
The SmartVIO controller is connected via I2C to all ports on a carrier. | Carrier | 1.4.2. Carrier |
The carrier includes a host (typically an FPGA). | Carrier | 1.4.2. Carrier |
The carrier includes +3.3V, +5V, and adjustable VIO rails for peripheral power. | Carrier | 4.2. Power Supplies |
The +3.3, +5V, and VIO rails on the carrier follow the required startup sequencing. | Carrier | 4.3 Supply Sequencing |
The carrier includes one or more VIO groups which share the same VIO power rail. | Carrier | 4.2.1. VIO Supply |
All transciever lanes on TXR2 and TXR4 ports are connected to transceiver-capable pins on the host. | Carrier | 2.4. Transceiver Pod/Port Pinout (TXR-4) |
AC-coupling capacitors are *not* included on transceiver lanes on the carrier. | Carrier | 2.5. Transceiver Pod/Port Signal Description |
Each port includes a unique R_GA geographical address resistor. | Carrier | SYZYGY Specification 5. SYZYGY DNA DNA Specification 2.1. Geographical Address |
Pod dimensions include the required width. | Pod | 3. Mechanical |
The pod includes a 10k pull on on the R_GA pin. | Pod | SYZYGY Specification 5. SYZYGY DNA DNA Specification 2.1. Geographical Address |
The pod includes an MCU with non-volatile storage to describe the pod’s functionality. | Pod | 1.4.3. Pod |
The pod does not output any signals to the carrier until the VIO supply has been enabled by the carrier. | Pod | 2.2. Standard Pod/Port Signal Description |
