Pin Description Pin # Pin Name Type Description
Latched select input to select spread spectrum amount at initial power up. 1 SS_SEL_TRI Input Tri-level 1 = -0.5% spread, M = Spread Off, 0 = Spread Off. This pin has both in- ternal pull-up and pull-down. Refer to SMBUS byte_1 bit 4, 3 = '01' to get -0.25% spread. 2 GND_XTAL Power — Ground for oscillator circuit 3 XTAL_IN/CLK Input — Crystal input or CMOS reference input 4 XTAL_OUT Output — Crystal output 5 VDD_OSC Power — Power supply for oscillator circuitry, nominal 3.3V 6 VDD_REFOUT Power — Power supply for buffered CMOS output 7 SADR/REFOUT Input/ Output CMOS Latch to select SMBus Address or LVCMOS REFOUT. This pin has an internal pull-down 8 GND_REFOUT Power — Ground for REFOUT 9 GND_DIG Power — Ground for digital circuitry 10 SCLK Input CMOS SMBUS clock input, 3.3V tolerant 11 SDATA Input/ Output CMOS SMBUS data line, 3.3V tolerant 12 VDD_DIG Power — Power supply for digital circuitry, nominal 3.3V 13, 21, 31, 39, 47 VDDO Power — Power supply for differential outputs Active-low input for enabling Q0 pair. This pin has an internal pulldown. 14 OE0# Input CMOS 1 =disable outputs, 0 = enable outputs 15 Q0+ Output HCSL Differential true clock output PI6CG33802C www.diodes.com January 2020 Document Number DS42298 Rev 3-2 2 Diodes Incorporated
