Reference Voltage Input/Output. When APDREF = 0, the buffered internal voltage reference is driven on
this pin as an output and can be used by other devices. When APDREF = 1, an external voltage
reference must be provided on this pin.

Digital and Analog Power Supply
Clock Select Input. When CLKSEL = 0, the DS8102 uses its internal 8MHz oscillator as a clock source.
When CLKSEL = 1, the DS8102 operates from an external clock source (which must be provided at
CLKIO).
Gain Select Input 0. This pin, along with G1, is used to select the gain setting for differential analog
input channel 0.
Gain Select Input 1. This pin, along with G0, is used to select the gain setting for differential analog
input channel 0.
Clock Input/Output. When CLKSEL = 0 (internal clock selected), the internal 8MHz clock is output on
this pin and can be used by external devices. When CLKSEL = 1 (external clock selected), an external
clock must be provided on this pin.
Manchester Encoder Output. This output pin provides a Manchester-encoded bit stream containing
output bits from both modulators interleaved with an alternating synchronization bit.
Reset. This input pin can be used to force the DS8102 into a shutdown (low-power) state by driving
RST = 0. If the external reset function is not used, this pin must be connected to V
operation. An RC circuit is not required on this pin for power-up, as this function is provided internally.
Analog Power-Down Reference. This input pin controls whether the internal voltage reference is
enabled. If APDREF = 0, the internal voltage reference is enabled and the voltage reference level is
driven out on V
reference must be provided on V
