Description The SL16020DC is a low power dissipation spread spectrum clock generator using SLI proprietary low jitter PLL. The SL16020DC provides two output clocks. REFCLK （Pin-9） which is a buffered output of the 27.000MHz input crystal and SSCLK （Pin-5） which is synthesized as 100.000MHz nominal by an internal PLL using the 27.00MHz external input crystal or clock. In addition， SSEL0 （Pin-7） and SSEL1 （Pin-3） spread percent selection control inputs enable users to select from 0.0% （no spread） to –1.5% down spread at 100.000MHz SSCLK output to reduce and optimize system EMI levels. The SL16020DC operates in an extended temperature range of -10 to +85°C.
