TriQuint’s GA1086 operates from 30 MHz to 67 MHz. This TTL-level clock buffer chip supports the tight timing requirements of high-performance microprocessors, with near zero input-to-output delay and very low pin-to-pin skew. The device offers 10 usable outputs synchronized in phase and frequency to a periodic clock input signal. One of the ten outputs is a onehalf clock output (CLK ÷ 2). With split termination, the GA1086 can be used to drive up to nineteen 15 pF loads, as shown in Figure 10.
