SY100EL91LZI

Translators, Level Shifters Overview

The SY100EL91LZI is a triple LVPECL-to-ECL or LVPECL-to-LVECL translator manufactured by Microchip Technology. It operates with a VCC supply of 3.0V to 3.8V and supports VEE supplies ranging from -4.2V to -5.5V for ECL mode, or -3.0V to -3.8V for LVECL mode. The device features a typical propagation delay of 620ps in differential mode and is housed in a 20-pin Wide SOIC (Z20-1) package. It is rated for an industrial operating temperature range of -40°C to +85°C.

Translators, Level Shifters FAQ

How should the PECL_VBB pin be utilized?

The PECL_VBB pin provides a reference voltage output intended for interfacing with single-ended PECL signals. When used, it must be bypassed to ground via a 0.01 µF capacitor.

What are the valid power supply configurations?

The device requires three power rails: VCC connected to the positive supply (3.0V to 3.8V), VEE connected to the negative supply (-4.2V to -5.5V for ECL or -3.0V to -3.8V for LVECL), and GND pins connected to the system ground plane.
