Pin Description Pin Number Pin Name Type Description
1 SADR_TRI Input Tri-level Latch to select SMBus Address. This pin has an internal pull-down. 2 BW_SEL_TRI Input Tri-level Latch to select low-loop bandwidth, bypass PLL, and high-loop band- width. This pin has both internal pull-up and pull-down. 3 NC — — Internal connected for feedback loop. Do not connect this pin. 4 NC — — Internal connected for feedback loop. Do not connect this pin. 5 VDD_R Power — Power supply for input differential buffers 6 IN+ Input — Differential true clock input 7 IN- Input — Differential complementary clock input 8 GND_R Power — Ground for input differential buffers 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 pull-down. 14 OE0# Input CMOS 1 =disable outputs, 0 = enable outputs 15 Q0+ Output HCSL Differential true clock output PI6CB33801 www.diodes.com January 2020 Document Number DS41288 Rev 5-2 2 Diodes Incorporated
