NOTE:
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM RATlNG conditions for extended periods may affect device reliability.
The SY10H842/100H842 are single supply, low skew translating 1:4 clock drivers.
The SY10H842 feature a 24mA TTL output stage, with AC performance specified into a 50pF load capacitance. A HIGH on the enable pin (EN) forces all outputs LOW.
As frequencies increase to 40MHz and above, precise timing and shaping of clock signals becomes extremely important. The SY10H842 solves several clock distribution problems such as minimizing skew 300ps), maximizing clock fanout (24mA drive), and precise duty cycle control through a proprietary differential internal design.
The SY10H842 version is compatible with 10KH ECL logic levels. The 100K version is compatible with 100K levels.
