= 5.5 V and worst case processing.
3. 2 mV (p-p) single-ended is the minimum input signal to achieve full clipping of the output signal. Typical an input
signal of 0.5 mV (p-p) single-ended results in a Bit Error Rate (BER) of less than 10

.
4. If the input is DC coupled, the preceding amplifier鈥檚 output offset voltage should not exceed these limits, in order to
avoid malfunctioning of the DC offset compensation circuit.
5. Specifications guaranteed by design and characterisation. Each device is tested at full operating speed to guarantee
RF functionality.

7. The reference current can be set by connecting a resistor between V

and pin RSET. The corresponding input
signal level detect range is from 2 to 12 mV (p-p) single-ended. See Section 鈥淚nput signal level detection鈥?for detailed
