INTEGRATED CIRCUITS FBL22041 3.3V BTL 7-bit Futurebus + transceiver (standard A-port) Product specification Supersedes data of 1998 Feb 02 IC23 Data Handbook 1998 Aug 12 Philips Semiconductors Philips Semiconductors Product specification 3.3V BTL 7-bit Futurebus+ transceiver (standard A-port) FBL22041 FEATURES * 7-bit BTL transceiver * Separate I/O on TTL A-port * Inverting * Three separate pairs of driver enables in a 1 bit, 3 bit, 3 bit arrangement * Drives heavily loaded backplanes with equivalent load impedances down to 10. * 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 * The A port includes a series resistor of 30 making external terminating resistors unnecessary * 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 DESCRIPTION The FBL22041 is a 7-bit bidirectional BTL transceiver and is intended to provide the electrical interface to a high performance wired-OR bus. The FBL22041 is an inverting transceiver. 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 insure very good noise margins by limiting the switching threshold to a narrow region centered at 1.55V. The FBL22041 is designed with a 30 series resistance in both the HIGH and LOW states of the output. The FBL22041 is pin and function compatible with FB2041 but operates at a 3.3V supply voltage, greatly reducing power consumption. * Built-in precision band-gap reference provides accurate receiver thresholds and improved noise immunity * Compatible with IEEE Futurebus+ or proprietary BTL backplanes * Controlled output ramp and multiple GND pins minimize ground bounce * Each BTL driver has a dedicated Bus GND for a signal return * Glitch-free power up/power down operation * Low ICC current QUICK REFERENCE DATA SYMBOL tPLH tPHL tPLH tPHL COB IOL PARAMETER Propagation delay AIn to Bn Propagation delay Bn to AOn TYPICAL 4.1 3.6 5.2 5.1 6 100 6.0 5.1 13.4 10.6 UNIT ns ns pF mA Output capacitance (B0 - B6 only) Output current (B0 - B6 only) Standby AIn to Bn (outputs Low or High) Bn to AOn (outputs Low) Bn to AOn (outputs High) ICC Supply Current mA ORDERING INFORMATION PACKAGE 52-pin Plastic Quad Flatpack COMMERCIAL RANGE VCC = 3.3V10%; Tamb = 0 to +70C FBL22041BB DWG No. SOT379-1 1998 Aug 12 2 853-2039 19863 Philips Semiconductors Product specification 3.3V BTL 7-bit Futurebus+ transceiver (standard A-port) FBL22041 TMS (option) TCK (option) BUS GND BIAS V OEA1 OEB0 OEB1 AO1 AO0 AI0 VCC VCC 52 51 50 49 48 47 46 45 44 43 42 41 40 LOGIC GND AI1 AI2 AO2 LOGIC GND AO3 LOGIC GND AI3 AI4 AO4 LOGIC GND AO5 LOGIC GND 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 BG VCC LOGIC GND TDO (option) TDI (option) BG GND AO6 VCC AI5 AI6 OEA2 OEA3 OEB2 OEB3 39 38 37 36 BUS GND B1 BUS GND B2 BUS GND B3 BUS GND B4 BUS GND B5 BUS GND B6 N/C 7-Bit Transceiver B0 35 34 33 32 31 30 29 28 27 52-lead PQFP SG00084 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 VCC 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. 1998 Aug 12 3 Philips Semiconductors Product specification 3.3V BTL 7-bit Futurebus+ transceiver (standard A-port) FBL22041 PIN DESCRIPTION SYMBOL ai0 - ai6 aO0 - aO6 b0 - b6 OEB0 OEB1 OEB2 OEB3 OEA1 OEA2 OEA3 bus gnd LOGIC gnd LOGIC/bus VCC BG VCC BIAS V TMS Tck Tdi Tdo BG GND PIN NUMBER 51, 2, 3, 8, 9, 14, 18 50, 52, 4, 6, 10, 12, 16 40, 38, 36, 34, 32, 30, 28 46 45 25 26 47 20 24 41, 39, 37, 35, 33, 31, 29 1, 5, 7, 11, 13, 15 23, 43, 49 17 48 42 44 22 21 19 TYPE Input Output i/o Input Input Input Input Input Input Input GND GND Power Power Power Input Input Input Output GND NAME AND FUNCTION Data inputs (TTL) 3-state outputs (TTL) Data inputs/Open Collector outputs, High current drive (BTL) Enables the Bn outputs when High Enables the B0 output when Low Enables the B1 - B3 outputs when Low Enables the B4 - B6 outputs when Low Enables the A0 outputs when High Enables the A1 - A3 outputs when High Enables the A4 - A6 outputs when High Bus ground (0V) Logic ground (0V) Positive supply voltage Positive supply voltage BAND GAP Positive supply voltage Test Mode Select (no-connect) Test Clock (no-connect) Test Data In (shorted to TDO) Test Data Out (TDI) BAND GAP GROUND (0V) 1998 Aug 12 4 Philips Semiconductors Product specification 3.3V BTL 7-bit Futurebus+ transceiver (standard A-port) FBL22041 FUNCTION TABLE MODE INPUTS AIn L AIn to Bn H L H L AI0 to B0 H L H L AI1 - AI3 to B1 - B3 H L H L AI4 - AI6 to B4 - B6 H L H Disable Bn outputs Disable B0 outputs Disable B1 - B3 outputs Disable B4 - B6 outputs Bn to AOn X X X X X X X X X X B0 to AO0 X X X X B1 - B3 to AO1 - AO3 X X X X B4 - B6 to AO4 - AO6 X X X Disable AOn outputs Disable AO0 outputs Disable AO1 - AO3 outputs Disable AO4 - AO6 outputs NOTES: H= L = X = Z = --= H** = B* = X X X X Bn* -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- X X X X X L H L H L H L H L H L H L H L H X X X X OEB0 H H H H H H H H H H H H H H H H L X H H H L L X X L L X X L L X X L L X X X X X X OEB1 L L L L L L L L X X X X X X X X X H H X X X X H H X X H H X X H H X X H H X X X X Z -- H** B* = = = = OEB2 L L L L X X X X L L L L X X X X X H X H X X X H H X X H H X X H H X X H H X X X X OEB3 L L L L X X X X X X X X L L L L X H X X H X X H H X X H H X X H H X X H H X X X X OEA1 L L H H L L H H L L H H L L H H X X X X X H H H H H H H H X X X X X X X X L L X X OEA2 L L H H L L H H L L H H L L H H X X X X X H H H H X X X X H H H H X X X X L X L X OEA3 L L H H L L H H L L H H L L H H X X X X X H H H H X X X X X X X X H H H H L X X L OUTPUTS AOn Z Z L H Z Z L H Z Z L H Z Z L H X X X X X H L H L H L H L H L H L H L H L Z Z Z Z Bn* H** L H** L H** L H** L H** L H** L H** L H** L H** H** H** H** H** Input Input Input Input Input Input Input Input Input Input Input Input Input Input Input Input X X X X High voltage level Low voltage level Don't care High-impedance (OFF) state Input not externally driven Goes to level of pull-up voltage Precaution should be taken to ensure B inputs do not float.
