The B-port interfaces to “Backplane Transceiver Logic” (See the
IEEE 1194.1 BTL standard). BTL features low power consumption
by reducing voltage swing (1Vp-p, between 1V and 2V) and reduced
capacitive loading by placing an internal series diode on the drivers.
BTL also provides incident wave switching, a necessity for high
performance backplanes.
There are three separate pairs of driver enables in a 1 bit, 3 bit, 3 bit
arrangement. The TTL/BTL output drivers for bit 0 are enabled with
OEA1/OEB1, output drivers for bits 1–2–3 are enabled with
OEA2/OEB2 and output drivers for bits 4–5–6 are enabled with
OEA3/OEB3.
The A-port operates at TTL levels with separate I/O. The 3-state
A-port drivers are enabled when OEAn goes High after an extra 6ns
delay which is built in to provide a break-before-make function.
When OEAn goes Low, A-port drivers become High impedance
without any extra delay. During power on/off cycles, the A-port
drivers are held in a High impedance state when V
CC
is below 1.3V.
The B-port has an output enable, OEB0, which affects all seven
drivers. When OEB0 is High and OEBn is Low the output driver will
be enabled. When OEB0 is Low or if OEBn is High, the B-port
drivers will be inactive and at the level of the backplane signal.
