TriQuint's TQ1090 is a configurable clock buffer which generates 11 outputs, operating over a wide range of frequencies from 33 MHz to 45MHz, 65 MHz to 90 MHz and 130 MHz to 180 MHz. The outputs are available at 1x, 2x and 4x, or at 1/2x, 1x and 2x, or at 1/4 x, 1/2 x and 1x the reference clock frequency, fREF.
When one of the Group A outputs (Q0Q4) of TQ1090 is used as feedback to the PLL, all Group A outputs will be at fREF, all Group B outputs (Q5Q8) will be at 2x fREF and all Group C outputs (Q9,Q10) will be at 4x fREF. When one of the Group B outputs is used as feedback to the PLL, all Group A outputs will be at 1/2 x fREF, all Group B outputs will be at fREF and all Group C outputs will be at 2x fREF. When one of the Group C outputs is used as feedback to the PLL, all Group A outputs will be at 1/4 x fREF, all Group B outputs will be at 1/2 x fREF and all Group C outputs will be at fREF.
A very stable internal Phase-Locked Loop (PLL) of TQ1090 provides low-jitter operation. This completely self-contained PLL requires no external capacitors or resistors. The PLL's Voltage-Controlled Oscillator (VCO) has a frequency range from 260 MHz to 360 MHz. By feeding back one of the output clocks to FBIN, the PLL TQ1090 continuously maintains frequency and phase synchronization between the reference clock (REFCLK) and each of the outputs.
