1) Min value Pin, Nin: VCC-Pin, Nin < 800 mV
2) Voltage (Pin-Nin) = 4 mVpp @Pin = -23 dBm
3) Hysteresis can be installed by a combination of Signal LOS and LLOS.
4) Open Collector Output type, I = 2 mA. Datarate depends on output load.
Termination with pullup resistor > 4.7 kΩ
5) No skipping clock cycles allowed down to < 10-3 BER
External adjustable.
6) Clock drift with no input 25 MHz
7) The alarm shall be asserted before 500 ns of phase shift on the RX clock is realized.
8) Consecutive identical bits 72 bits.
9) Supply current = IEE ( current without ECL output current).
