Figure 1. Block Diagram and operates over a wide range of frequencies—from 24 MHz to 105 MHz. A very stable internal Phase-Locked Loop (PLL) provides low-jitter operation. This completely self-contained PLL requires no external capacitors or resistors. between the reference clock (REFCLK) and each of the outputs. of sourcing and sinking 30 mA.
the GA1085 to operate between 24 MHz and 105 MHz. the reference clock is divided by 4, 5, or 6. with 30 mA symmetric drive and a minimum VOH of 2.4 V. required for synchronization (TSYNC) is 500 ms. Table 1. Frequency Mode Selection Note: 1. This mode produces outputs with 40/60 duty cycle for Q4 – Q8 only.

- The PLL maintains alignment of CLK and FBIN at all times. This specification applies to the rising edge only because the inpu t duty
cycle can vary while the output duty cycle is typically 50/50. The delay t PD is measured at the 1.5 V level between CLK and FBIN.
- Skew specifies the width of the window in which outputs switch, and is measured at 1.5 V.
- This specification represents the deviation from 50/50 on the outputs.
- Jitter specifications refer to peak-to-peak value. t JR is the jitter on the output with respect to the reference clock.
tJP is the jitter on the output with respect to the output’s previous rising edge.
- tSYNC is the time required for the PLL to synchronize; this assumes the presence of a CLK signal and
a connection from one of the outputs to FBIN. Figure 3. AC Test Circuit
