PCKEL14PW,112 Overview
20-TSSOP (0.173, 4.40mm Width) case is available for the cut smart buffer. In case Tube, the cut smart buffer is available. Normal operation has a maximum value of 1GHz. A total of 20 terminations have been found in it. The supply voltage of 2.5V is capable of providing high efficiency. If this is the case, it will be mounted as Surface Mount. This electronic part is classified as Fanout Buffer (Distribution), Multiplexer. If you wish to ensure reliable performance, you should set the temperature to -40°C~85°C. In general, it should be able to work with a power source of 2.375V~3.8V volts. On this board, there is a pin count of 20. Buffer IC is PECL that is output. The structure belongs to the PCKEL14 family of structures. This value is set to 3.8V for the maximum available supply voltage (Vsup). A voltage higher than 2.375V is necessary for normal operation of the system. There is a -2.5/-3.3/2.5/3.3V volt supply that powers the timeing clock. With the help of this gadget, it is also possible to obtain NECL MODE: VCC=0 WITH VEE= -2.375V TO -3.8V.
