This voltage can be less than or equal to VIO. 7 P_EN The precharge enable input which controls the precharge pull-up resistors. When this active high control signal is set to ’1’, the precharge of all channels is enabled. 8 GND The ground voltage reference for the CMCPCI102BT/BR. 9 CAP A capacitor must be placed from this pin to GND. The recommended value is 0.01 µF,16V. 20 SW_EN The series switch enable input. When this active high control signal is set to ’1’, the series switch between the channel’s backplane-side terminal and device-side terminal is closed. When this sig- nal is cleared to ’0’, the switch is open. 21 3_EN The enable signal for the device-side channel pull-up mechanism when 3.3V is the supply volt- age. When this active high control signal is set to ’1’, the 2.7k Ω pull-up resistor which pulls up the channel to the supply rail is engaged. Otherwise, this pin should be set to ’0’. 22 5_EN The enable signal for the device-side channel pull-up mechanism when 5V is the supply voltage. When this active high control signal is set to ’1’, the 1k Ωpull-up resistor which pulls up the channel to the supply rail is engaged. Otherwise, this pin should be set to ’0’. 23 VIO The positive supply voltage for the CMCPCI102BT/BR. Either 3.3V or 5V may be used. 28-pin TSSOP 1 2 3 4 5 6 7 8 20 19 18 17 21 22 9 10 24 23 25 26 11 12 27 28 A5 1V P_EN GND CAP A6 A7 A8 A1 A2 A3 A4 B2 B3 B4 B5 VIO 5_EN 3_EN SW_EN B6 B7 B8 B1 13 14 16 15 B9 B10 A9 A10 PACKAGE / PINOUT DIAGRAM Note: This drawing is not to scale.
