It is specifically designed for driving 50-Ω transmission lines. 25 6 Y0 Y0 Y1 VCC0 Y1 Y2 Y2 Y4 Y3 Y3 D VCC0 D FN PACKAGE (TOP VIEW) Low-Output Skew for Clock-Distribution Applications Differential Low-Voltage Pseudo-ECL (LVPECL)-Compatible Inputs and Outputs Distributes Differential Clock Inputs to Nine Differential Clock Outputs Output Reference Voltage, VREF , Allows Distribution From a Single-Ended Clock Input Single-Ended LVPECL-Compatible Output Enable Packaged in Plastic Chip Carrier NC V REF CLKIN V CC CLKIN OE GND D NC – No internal connection When the output-enable (OE) is low, the nine differential outputs switch at the same frequency as the differential clock inputs. When OE is high, the nine differential outputs are in static states (Y outputs are in the low state, Y outputs are in the high state). The VREF output can be strapped to the CLKIN input for a single-ended CLKIN input. The CDC111 is characterized for operation from 0°C to 70°C.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The maximum package power dissipation is calculated using a juction temperature of 150_C and a board trace length of 750 mils.
