Product specification
9-bit BTL 3.3V latched/registered/pass-thru Futurebus+ transceiver with 30Ω termination
FBL22031
FEATURES
path
Latched, registered or straight through in either A to B or B to A Drives heavily loaded backplanes with equivalent load
impedances down to 10Ω.
High drive 100mA BTL open collector drivers on B-port Allows incident wave switching in heavily loaded backplane buses Reduced BTL voltage swing produces less noise and reduces
power consumption
Tight output skew Supports live insertion Pins for the optional JTAG boundary scan function are provided High density packaging in plastic Quad Flatpack 5V compatible I/O on A-port Same pinout and function as the FBL2033 except for 30Ω series
termination
The A output includes a a series resistor of 30Ω making external
terminating resistors unnecessary
Built-in precision band-gap reference provides accurate receiver
thresholds and improved noise immunity
Compatible with IEEE Futurebus+ or proprietary BTL backplanes Each BTL driver has a dedicated Bus GND for a signal return Controlled output ramp and multiple GND pins minimize ground
bounce
