Ineltek adds ChronoPHY Ethernet transceivers

The excellent know-how that has already been spent on Aeonsemi’s Arcadium oscillators has now been applied to this 10G EthernetPHY family to achieve excellent performance in the fields of network synchronization and latency.

Applications in high-definition video transmission, data transfer for AR/VR applications, or streaming and gaming environments call for increasingly higher predictability combined with lower latency and higher data rates.

Next-generation WiFi – WiFi-6 and WiFi-7 – also required broad connectivity on the wired side. In corporate networks, the required data bandwidth is constantly growing.

Due to their unique timing architecture, nanosecond network synchronization accuracy can be achieved when using ChronoPHY transceivers.

The transceivers are IEEE802.3 and IEEE1588 compliant. Samples as well as evaluation boards are already available.

Mass production is planned for September 2023.

All ChronoPHY derivatives operate in the industrial temperature range from -40°C to +85°C.

Features of the ChronoPHY-Series are:

• 10GBase-T, 5GBase-T, 2.5GBase-T, 1000Base-T, and 100Base-TX
• 802.3an/802.3bz/802.3ab/802.3u compliant
• 1ns PTP time stamping resolution

• Flexible reference input clock of 50MHz or 156.25MHz
• Any rate fractional frequency SyncE output clock: 25MHz to 250MHz
• Ultra-low close-in phase noise SyncE PLL
• Dual-Media Support with 2 SERDES Optionen.
• Package: 11×11 mm² or 7x7mm² BGA

The “J” version adds an integrated SyncE jitter filter and the ability to have an any fractional frequency SyncE output clock from 25MHz to 250MHz. All parts have 1588 PTP time stamping available.
