MC100LVE210, MC100E210 Low Voltage Dual 1:4, 1:5 Differential Fanout Buffer ECL/PECL Compatible 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 part–to–part skew down to an output–to–output 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. For applications which require a single–ended input, the VBB reference voltage is supplied. For single–ended input applications the VBB reference should be connected to the unused CLK input of a differential pair and bypassed to ground via a 0.01f capacitor. The input signal is then driven into the selected CLK input. To ensure that the tight skew specification is met it is necessary that both sides of the differential output are identically terminated, even if only one side is being used. In most applications all nine differential pairs will be used and therefore terminated. In the case where fewer than nine pairs are used it is necessary to t……
