SY100ELT982KG

Translators, Level Shifters Overview

The SY100ELT982KG is a high-speed PECL-to-CML translator manufactured by Microchip Technology, utilizing bipolar ASSET technology. It operates on a single +5V power supply and supports data rates up to 1.25Gbps. The device features differential inputs with a 75KΩ pull-down resistor and complementary open-collector outputs capable of driving a peak current of 25mA. Output current is adjustable via an external RSET resistor connected to the VREF pin. It includes a separate output enable input (/EN) and is housed in a 10-pin MSOP package.

Translators, Level Shifters Feature Summary

Translators, Level Shifters FAQ

How is the output current adjusted?

The output current is controlled by the DC current flowing through an external resistor (RSET) connected between the VREF pin and ground.

What happens when the output enable input is HIGH?

When the /EN input is asserted HIGH, the OUT pin drives the full output current while the /OUT pin is disabled (0mA).
