SY100ELT982KI

Translators, Level Shifters Overview

The SY100ELT982KI 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 DC controlled via an external RSET resistor connected to the VREF pin. Propagation delay from DIN to OUT ranges from 480ps to 1000ps, while rise/fall time is typically 200ps. It functions within an operating temperature range of 0°C to +85°C and is housed in a 10-pin MSOP package.

Translators, Level Shifters FAQ

How is the output current adjusted?

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

What happens when the enable pin is HIGH?

When the /EN input is asserted HIGH, the OUT pin drives at IOUT and the /OUT pin is disabled (0mA).
