SY89223LMI-TR

Translators, Level Shifters Overview

The SY89223LMI-TR is a dual differential LVPECL-to-LVTTL translator manufactured by Microchip Technology. It operates from a 3.3V ±10% power supply and supports maximum input frequencies up to 160MHz. The device features propagation delays under 2.5ns and within-device skew less than 300ps. It accepts 10k or 100k differential LVPECL inputs and provides 24mA LVTTL outputs. The component is housed in an ultra-small 8-pin MLF package and is rated for the industrial temperature range of –40°C to +85°C.
