3 / 17 page MARCH 8, 2017 3 7-OUTPUT 1.5V PCIE GEN1-2-3 FANOUT BUFFER 9DBU0731 DATASHEET Pin Descriptions PIN # PIN NAME PIN TYPE DESCRIPTION 1 vSADR_tri LATCHED IN Tri-level latch to select SMBus Address. It has an internal 120kohm pull down resistor. See SMBus Address Selection Table. 2vOE6# IN Active low input for enabling output 6. This pin has an internal 120kohm pull-down. 1 =disable outputs, 0 = enable outputs 3 DIF6 OUT Differential true clock output. 4 DIF6# OUT Differential complementary clock output. 5 VDDR1.5 PWR 1.5V power for differential input clock (receiver). This VDD should be treated as an Analog power rail and filtered appropriately. 6 CLK_IN IN True Input for differential reference clock. 7 CLK_IN# IN Complementary Input for differential reference clock. 8 GNDDIG GND Ground pin for digital circuitry. 9 SCLK_3.3 IN Clock pin of SMBus circuitry, 3.3V tolerant. 10 SDATA_3.3 I/O Data pin for SMBus circuitry, 3.3V tolerant. 11 VDDDIG1.5 PWR 1.5V digital power (dirty power) 12 VDDIO PWR Power supply for differential outputs 13 vOE0# IN Active low input for enabling output 0. This pin has an internal 120kohm pull-down. 1 =disable outputs, 0 = enable outputs 14 DIF0 OUT Differential true clock output. 15 DIF0# OUT Differential complementary clock output. 16 VDD1.5 PWR Power supply, nominally 1.5V 17 VDDIO PWR Power supply for differential outputs 18 DIF1 OUT Differential true clock output. 19 DIF1# OUT Differential complementary clock output. 20 NC N/A No connection. 21 vOE1# IN Active low input for enabling output 1. This pin has an internal 120kohm pull-down. 1 =disable outputs, 0 = enable outputs 22 DIF2 OUT Differential true clock output. 23 DIF2# OUT Differential complementary clock output. 24 vOE2# IN Active low input for enabling output 2. This pin has an internal 120kohm pull-down. 1 =disable outputs, 0 = enable outputs 25 VDDO1.5 PWR Power supply for outputs, nominally 1.5V. 26 VDDIO PWR Power supply for differential outputs 27 DIF3 OUT Differential true clock output. 28 DIF3# OUT Differential complementary clock output. 29 vOE3# IN Active low input for enabling output 3. This pin has an internal 120kohm pull-down. 1 =disable outputs, 0 = enable outputs 30 NC N/A No connection. 31 VDD1.5 PWR Power supply, nominally 1.5V 32 VDDIO PWR Power supply for differential outputs 33 DIF4 OUT Differential true clock output. 34 DIF4# OUT Differential complementary clock output. 35 vOE4# IN Active low input for enabling output 4. This pin has an internal 120kohm pull-down. 1 =disable outputs, 0 = enable outputs 36 DIF5 OUT Differential true clock output. 37 DIF5# OUT Differential complementary clock output. 38 vOE5# IN Active low input for enabling output 5. This pin has an internal 120kohm pull-down. 1 =disable outputs, 0 = enable outputs 39 VDDIO PWR Power supply for differential outputs 40 ^CKPWRGD_PD# IN Input notifies device to sample latched inputs and start up on first high assertion. Low enters Power Down Mode, subsequent high assertions exit Power Down Mode. This pin has internal 120kohm pull-up resistor. 41 EPAD GND Connect paddle to ground. |
