FUNCTION
Output Deemphasis Control LSB, Channel B. OEQB0 has a 375kI (typ) internal pulldown resistor.
Input Equalization Control MSB, Channel B. INEQB1 has a 375kI (typ) internal pulldown resistor.
Input Equalization Control LSB, Channel B. INEQB0 has a 375kI (typ) internal pulldown resistor.
Internally Connected. Leave I.C. unconnected.
Inverting Input, Channel B
Noninverting Input, Channel B
Receiver Detection Control Bit. Toggle RXDET to initiate receiver detection. RXDET has a 375kI (typ)
internal pulldown resistor.
Inverting Output, Channel A
Noninverting Output, Channel A
Output Deemphasis Control LSB, Channel A. OEQA0 has a 375kI (typ) internal pulldown resistor.
Output Deemphasis Control Bit 1, Channel A. OEQA1 has a 375kI (typ) internal pulldown resistor.
Output Deemphasis Control MSB, Channel A. OEQA2 has a 375kI (typ) internal pulldown resistor.
Input Equalization Control LSB, Channel A. INEQA0 has a 375kI (typ) internal pulldown resistor.
Input Equalization Control MSB, Channel A. INEQA1 has a 375kI (typ) internal pulldown resistor.
Exposed Pad. Internally connected to GND. Connect EP to a large ground plane to maximize thermal
performance and ground conductivity to the device. Do not use EP as the only GND connection.
