NOTES:
1. No signal to signal present, or a switch from another data rate to 270Mb/s.
2. Power supply noise 50mV

at 15kHz, 100kHz, 1MHz sinusoidal modulation.
3. See
Figure 2-1
.
4. When the serial input to the GS9090 is removed, the PCLK output signal will continue to operate at 27MHz and the internal VCO will
remain at this frequency within +/- 7.5% over the range -20

5. Timing includes the following outputs: DOUT[9:0], STAT[3:0]. When the FIFO is enabled, the outputs are measured with respect to
RD_CLK.
