SY100E310L is a 3.3V, precision 2:8 ECL/PECL fanout buffer optimized for precision low-skew clock distribution. The SY100E310L features fully differential clock paths to minimize both device and system skew resulting in skew performance of < 50ps. In addition, the device includes a 2:1 multiplexer input for redundant switchover applications. The SY100E310L is optimized for low voltage +3.3V LVPECL or –3.3V LVECL applications.
The SY100E310L from Micrel is a 3.3 V precision 2:8 ECL/PECL differential fanout buffer optimized for low‑skew clock distribution. It provides fully differential clock paths with typical skew under 50 ps and includes a 2:1 multiplexer for redundant switchover applications.
The device is offered in a 28‑pin PLCC package and operates over an industrial temperature range of –40 °C to +85 °C. Electrical specifications include a supply voltage range of 3.0 V to 3.6 V, typical maximum frequency of 800 MHz, and detailed DC and AC characteristics for LVPECL and LVNECL modes. Applications include high‑end server clock distribution and redundant clock switchover.
