July 2005 rev 0.2 3.3V 1:10 LVCMOS PLL Clock Generator
Features
1:10 PLL based low-voltage clock generator Supports zero-delay operation 3.3V power supply
ASM5I9658
and the reference clock frequency determines the VCO frequency. Both must be selected to match the VCO frequency range. The internal VCO of the ASM5I9658 is running at either 2x or 4x of the reference clock frequency. The ASM5I9658 has a differential LVPECL reference input along with an external feedback input. The ASM5I9658 is ideal for use as a zero delay, low skew fanout buffer. The device performance has been tuned and optimized for zero delay performance. The PLL_EN and BYPASS controls select the PLL bypass configuration for test and diagnosis.
