BTL also provides incident wave switching, a necessity for high performance backplanes. DESCRIPTION The FBL22033 is an 8-bit transceiver featuring a split input (AI) and output (AO) bus on the TTL-level side. The common I/O, open collector B port operates at BTL signal levels. The logic element for data flow in each direction is controlled by two pairs of mode select inputs (SBA0 and SBA1 for B-to-A, SAB0 and SAB1 for A-to-B). It can be configured as a buffer, a register, or a D-type latch. Output clamps are provided on the BTL outputs to further reduce switching noise. The “VOH” clamp reduces inductive ringing effects during a Low-to-High transition. The “VOH” clamp is always active. The other clamp, the “trapped reflection” clamp, clamps out ringing below the BTL 0.5V VOL level. This clamp remains active for approximately 100ns after a High-to-Low transition. When configured in the buffer mode, the inverse of the input data appears at the output port. In the flip-flop mode, data is stored on the rising edge of the appropriate clock input (LCAB or LCBA). In the latch mode, clock pins serve as transparent-High latch enables. Regardless of the mode, data is inverted from input to output. To support live insertion, OEB0 is held Low during power on/off cycles to ensure glitch- free B port drivers. Proper bias for B port drivers during live insertion is provided by the BIAS V pin when at a 3.3V level while VCC is Low. The BIAS V pin is a low current input which will reverse-bias the BTL driver series Schottky diode, and also bias the B port output pins to a voltage between 1.62V and 2.1V. This bias function is in accordance with IEEE BTL Standard 1194.1. If live insertion is not a requirement, the BIAS V pin should be tied to a VCC pin. Data flow in the B-to-A direction, regardless of the logic element selected, is further controlled by the Loopback input. When the Loopback input is High the output of the selected A-to-B logic element (not inverted) becomes the B-to-A input. The 3-State AO port is enabled by asserting a High level on OEA. The B port has two output enables, OEB0 and OEB1. Only when OEB0 is High and OEB1 is Low is the output enabled. When either OEB0 is Low or OEB1 is High, the B-port is inactive and is pulled to the level of the pull-up voltage. New data can be entered in the flip-flop and latched modes or can be retained while the associated outputs are in 3-State (AO port) or inactive (B port). The LOGIC GND and BUS GND pins are isolated inside the package to minimize noise coupling between the BTL and TTL sides. These pins should be tied to a common ground external to the package. Each BTL driver has an associated BUS GND pin that acts as a signal return path and these BUS GND pins are internally isolated from each other. In the event of a ground return fault, a “hard” signal failure occurs instead of a pattern dependent error that may be very infrequent and impossible to trouble- shoot. The B-port drivers are Low-capacitance open collectors with controlled ramp and are designed to sink 100mA. Precision band gap references on the B-port ensure very good noise margins by limiting the switching threshold to a narrow region centered at 1.55V. As with any high power device thermal considerations are critical. It is recommended that airflow (300Ifpm) and/or thermal mounting be used to ensure proper junction temperature. The B-port interfaces to “Backplane Transceiver Logic” (see the IEEE 1194.1 BTL standard).
