Clock Sources
Three on-board oscillators (33.33, 50, and 74.25 MHz) are available to drive the Ti180 PLL
input pin and clock input. Additionally, there is a dedicated 25 MHz on-board oscillator as
the MIPI clock source.
Table 1: Oscillator and Clock Generator Sources
Clock Source Ti180 Pin Name PLL Resource
33.33 MHz oscillator GPIOL_32_PLLIN1 PLL_TL2
50 MHz oscillator GPIOB_P_11_PLLIN0 PLL_BL1
74.25 MHz oscillator GPIOL_26_PLLIN1 PLL_TL0
GPIOL_06_CLK27_P MIPI0 dedicated PLL
GPIOL_07 MIPI1 dedicated PLL
GPIOL_27_CLK28_P MIPI2 dedicated PLL
25 MHz oscillator
GPIOL_28_CLK29_P MIPI3 dedicated PLL
Note: The Efinity Interface Designer issues an unrouted clkmux input error if more than 8 GCLK resources
are used on the left side of Ti180 FPGA. To solve this, assign one of the clocks, for example MIPI clock
TX0, to use the RCLK instead of the GCLK. For more information, refer to the Clock and Control Network
section of the Ti180 Data Sheet .
