| Data ports | Number: 18 <br /> Speed: 1 and/or 10 Gbps | |
|
|
|
| Mgmt ports| 2 Ethernet (SFP cage + simple RJ45) <br /> USB Mini-B | **TB-I: standard/common management interfaces <br /> on Ethernet switches (USB Mini-B, RS232, others)** |
|

| CLK IOs | Type: SMA <br />IN_1: 10 MHz <br />IN_2: 1 PPS <br />IN_3: AUX <br /> OUT_1: 10 MHz<br /> OUT_2: 1 PPS <br /> OUT_3: 62.5 MHz <br /> OUT_4: AUX (abscal) <br /> (all switchable between High-Z and 50 Ohm) | Check how SMA and AUX IN/OUTSMA can fit <br /> IN_3 AUX could be used in the future for internal TIC... <br /> **TBI: standardization of voltage levels and rise time, possibility to disable inputs to improve noise** |

*NOTE: There is no support for port speeds higher than 10 Gbps (coherent, 25Gbps and 100Gbps) - there is no real requirements for such feature and it would result in substantial cost.*
|
|
|
*NOTE: The chosen FPGA allows for 20 ports, yet we consider 18 sufficient, usually people ask for less.*
