TriQuint Semiconductor GA1086
the GA1086 can be used to drive up to nineteen 15 pF loads, as shown in Figure 10. The tight control over phase and frequency of the output clocks is achieved with a 400 MHz internal Phase-Locked Loop (PLL). By feeding back one of the output clocks to FBIN, the on-chip PLL continuously maintains synchronization between the input clock (CLK) and all ten outputs.| Part No. | GA1086 |

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-topin 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, Any drift or gradual variation in the system clock is matched and tracked at the ten outputs. The GA1086 output buffers are symmetric, each sourcing and sinking up to 30 mA of drive current.
