SY89223L 3.3V DUAL DIFFERENTIAL Precision Edge SY89223L LVPECL-to-LVTTL TRANSLATOR FEATURES f >160MHz MAX 3.3V 10% power supply Precision Edge <2.5ns propagation delay <300ps within-device skew DESCRIPTION Differential LVPECL inputs 24mA LVTTL outputs The SY89223L is a 3.3V, precision dual differential LVPECL-to-LVTTL translator. The ultra-small 8-pin MLF Industrial temperature range: 40C to +85C package and the low skew, dual gate design of this Available in an ultra-small 8-pin (2mm 2mm) MLF translator makes it ideal for applications which require package the translation of a clock and a data signal. The SY89223L translator accepts 10k or 100k differential LVPECL inputs.
