2 / 10 page 2 Precision Edge® SY89543L Micrel, Inc. M9999-071505 hbwhelp@micrel.com or (408) 955-1690 Pin Number Pin Name Pin Function 4, 2, 32, 30, INA0, /INA0, Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs 27, 25, 23, 21 INA1, /INA1, accept AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally INB0, /INB0, terminates to a VT pin through 50Ω. Note that these inputs will default to an indeterminate INB1, /INB1 state if left open. Unused differential input pairs can be terminated by connecting one input to VCC and the complementary input to GND through a 1kΩ resistor. The VT pin is to be left open in this configuration. Please refer to the “Input Interface Applications” section for more details. 3, 31, 26, 22 VTA0 , VTA1, Input Termination Center-Tap: Each side of the differential input pair, terminates to a VT VTB0, VTB1 pin. The VTA0, VTA1, VTB0, VTB1 pins provide a center-tap to a termination network for maximum interface flexibility. See “Input Interface Applications” section for more details. 6, 19 SELA, SELB These single-ended TTL/CMOS compatible inputs select the inputs to the multiplexers. Note that these inputs are internally connected to a 25k Ω pull-up resistor and will default to logic HIGH state if left open. 1, 5, 8, 17, 20, VCC Positive Power Supply: Bypass with 0.1 µF||0.01µF low ESR capacitors. The 0.01µF 24, 28, 29 capacitor should be as close to VCC pin as possible. 10, 11, 14, 15 QA, /QA, Differential Outputs: This differential LVDS output pair provides a copy of the selected QB, /QB input. It is a logic function of the INA0, INA1, INB0, INB1 and SELA and SELB inputs. Please refer to the “Truth Table” for details. Unused output pairs must be terminated with 100 Ω across the differential pair. 7, 9, 12, 13, 16, 18 GND, Ground: Ground pin and exposed pad must be connected to the same ground plane.
