PCKEP14D,112 Overview
There is a case available for the cut smart buffer in 20-SOIC (0.295, 7.50mm Width). This package is packaged in the form of a Tube. For normal operation, 2GHz is the maximum value. It has 20 terminations in it, which means that it is terminated. Supply voltages of 2.5V are capable of achieving high efficiency. In this case, it will be mounted by Surface Mount. A classification of Fanout Buffer (Distribution), Multiplexer is assigned to this electronic part. Setting the temperature to -40°C~85°C will ensure reliable performance. Ideally, it should be able to operate from 2.375V~3.8V volts. There are 20 pins on the clock buffer. There is a value of PECL as the output. As a member of the PCKEP14 family, it falls under that category. Vsup is set to 3.8V as the maximum supply voltage. As a general rule, the supply voltage (Vsup) should be maintained above 2.375V. The timeing clock is powered by a power supply of -2.5/-3.3/2.5/3.3V volts. By utilizing this gadget, one can also obtain NECL MODE: VEE = -2.375 V TO -3.8 V WITH VCC = 0 V.
