LOS or SD selection, TTL input. Set high, connect to VCC, or leave open to select LOS. Set low
or connect to GND to select SD.
Loss-of-Signal Level Set. A resistor from this pin to V
amplitude at which LOS will be asserted.
Loss-of-Signal (LOS selected): asserts high when the data input amplitude falls below the
threshold set by LOS
Signal Detect (SD selected): asserts low when the data input amplitude falls below the threshold
set by LOS
Active low TTL/CMOS. Internally pulled-up with 75kΩ. Connect to GND or apply a low level
signal (<0.8 V) to enable the post amp output. Can be shorted to LOS/SD (pin 3) to create a
squelch function. The polarity of this input follows the polarity of LOS/SD.
SY88236L: Driver Non-inverting input data. Internally terminated with 50 Ω to a reference
voltage.
SY88236AL: Driver Non-inverting input data. No internal termination.
SY88236L: Driver inverting input data. Internally terminated with 50 Ω to a reference voltage.
SY88236AL: Driver inverting input data. No internal termination.
Non-Inverting burst enable. Accepts any input, single-ended or differential: TTL/CMOS,
LVPECL, CML, LVDS, and HSTL. BEN requires an external termination. See Figure 2-a-d.
Inverting burst enable. Accepts any input, single-ended or differential: TTL/CMOS, LVPECL,
CML, LVDS, and HSTL. BEN requires an external termination. See Figure 2-a-d.
Internally pulled-up. Pull-down with a 22kΩ or lower resistance or apply a low level signal (<0.8
V) to enable bias and modulation. Keep floating or apply a high level (>2V) to disable bias and
modulation.
