2 / 10 page 2 Precision Edge® SY89545L Micrel, Inc. M9999-060308 hbwhelp@micrel.com or (408) 955-1690 Pin Number Pin Name Pin Function 4, 2, 32, IN0, /IN0, Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs 30, 27, 25, 23, 21 IN1, /IN1, accept AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally IN2, /IN2, terminates to a VT pin through 50Ω. Note that these inputs will default to an indeterminate IN3, /IN3 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 VT0, VT1, Input Termination Center-Tap: Each side of the differential input pair, terminates to a VT VT2, VT3 pin. The VT0, VT1, VT2, VT3 pins provide a center-tap to a termination network for maximum interface flexibility. See “Input Interface Applications” section for more details. 6, 19 SEL0, SEL1 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 a logic HIGH state if left open. 1, 5, 8, VCC Positive Power Supply: Bypass with 0.1 µF0.01µF low ESR capacitors. The 0.01µF 17, 20, 24, 28, 29 capacitor should be as close to VCC pin as possible. 10, 11 Q, /Q Differential Outputs: This LVDS output pair is the output of the device. It is a logic function of the IN0, IN1, IN0, IN1 and SEL0 inputs. Please refer to the “Truth Table’” for details. 7, 9, 12, 13, 16, 18 GND, Ground: Ground pin and exposed pad must be connected to the same ground plane. Exposed pad 14, 15 NC No connect. (Unused pins).
