The MC100LVE210 is a low voltage, low skew dual differential ECL fanout buffer designed with clock distribution in mind. The device features two fanout buffers, a 1:4 and a 1:5 buffer, on a single chip. The device features fully differential clock paths to minimize both device and system skew. The dual buffer allows for the fanout of two signals through a single chip, thus reducing the skew between the two fundamental signals from a parttopart skew down to an outputtooutput skew. This capability reduces the skew by a factor of 4 as compared to using two LVE111's to accomplish the same task. The MC100LVE210 works from a 3.3V supply while the MC100E210 provides identical function and performance from a standard 4.5V 100E voltage supply.
