SY898531L

In Production

The SY898531L is a 3.3V, low skew, 1:9 LVPECL fanout buffer with two selectable clock input pairs. Most standard differential input levels can be applied to the CLK, /CLK pair while LVPECL, CML, or SSTL input levels can be applied to the PCLK, /PCLK pair. To eliminate runt pulses on the outputs during asynchronous assertion/de-assertion of the clock enable pin, the clock enable is synchronized with the input signal.The SY898531L operates from a 3.3V ±5% supply and is guaranteed over the full industrial temperature range of 0°C to +70°C. The SY898531L is part of Micrel’s highspeed, Precision Edge product line. ...
