GPCLK1 and GPCLK2 pins on the CPLD (J5 and J12) are used to receive TCLK1 and TCLK3 into the
AdvancedMC module.
The DS90LV028A Dual CMOS Differential Line Receiver is used to convert both TCLK1 and TCLK3
into single ended TTL clocks. A DS90LV049, LVDS Dual Line Driver with Dual Line Receiver is used to
convert between single ended differentials. 100-Ω resistors are required at both the output terminals of the
DS90LV049 in order to correctly terminate the clock signals. Clocking schemes of both the DS90LV049
and DS90LV028A are shown in

The following subsections describe general board configuration.
5.4.1
Two separate power rails are available on the card, as follows:
All of the required voltages for the card are generated locally on board from these 12 V and 3.3 V power
supplies. Several smaller power modules use this 12 V intermediate bus to generate the required voltages.
