Pin Functions

PIN TYPE DESCRIPTION
NAME NUMBER
VCC 5 Power 3.3-V supply for the device
GND 1 Ground Device ground
INP0, INN0 6, 7 Input Differential input pair or single-ended input. Unused input pair can be left floating.
INP1, INN1 3, 4 Input Redundant differential input pair or single-ended input. Unused input pair can be left floating.
OUTP3, OUTN3 15, 16 Output Differential LVPECL output pair no. 3. Unused output pair can be left floating.
OUTP2, OUTN2 13, 14 Output Differential LVPECL output pair no. 2. Unused output pair can be left floating.
OUTP1, OUTN1 11, 12 Output Differential LVPECL output pair no. 1. Unused output pair can be left floating.
OUTP0 OUTN0 9, 10 Output Differential LVPECL output pair no. 0. Unused output pair can be left floating.
VAC_REF 8 — Bias voltage output for capacitive-coupled inputs. Do not use VAC_REF at VCC < 3 V. If used, it is recommended to use a 0.1-μF capacitor to GND on this pin. The output current is limited to 2 mA.
IN_SEL 2 — Pulldown (see Terminal Characteristics)
MUX select input for input choice (see Table 1)
