The SY88923AV limiting post amplifier with its high
gain and wide bandwidth is ideal for use as a post
amplifier in fiber-optic receivers with data rates up to
3.2Gbps. Signals as small as 5mVp-p can be amplified
to drive devices with PECL inputs. The SY88923AV
generates a chatter-free Loss-of-Signal (LOS) open
collector TTL output.
The SY88923AV incorporates a programmable level
detect function to identify when the input signal has been
lost. The LOS output will change from logic “LOW” to logic
“HIGH” when input signal is smaller than the swing set by
LOS
LVL
. This information can be fed back to the EN input
of the device to maintain stability under loss-of-signal
condition. Using LOS
LVL
pin, the sensitivity of the level
detection can be adjusted. The LOS
LVL
voltage can be set
by connecting a resistor divider between V
CC
and V
REF
shown in Figure 3. “
Typical Operating Characteristics
on
page 6 show the relationship between input level sensitivity
and the voltage set on LOS
LVL.
The LOS output is a TTL open collector output that
requires a pull-up resistor for proper operation, Figure 1.
