The SY88943V 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 2.5Gbps.
Signals as small as 5mVp-p can be amplified to drive
devices with PECL inputs. The SY88943V generates a
chatter-free Signal Detect (SD) open collector TTL output.
The SY88943V incorporates a programmable level detect
function to identify when the input signal has been lost.
The SD output will change from logic “HIGH” to logic “LOW”
when input signal is smaller than the swing set by SD
LVL
.
This information can be fed back to the EN input of the
device to maintain stability under loss of signal condition.
Using SD
LVL
pin, the sensitivity of the level detection can
be adjusted. The SD
LVL
voltage can be set by connecting
a resistor divider between V
CC
and V
REF
as shown in Figure
3. Figure 4, 5, 6, and 7 show the relationship between
input level sensitivity and the voltage set on SD
LVL
.
The SD output is a TTL open collector output that
requires a pull-up resistor for proper operation, Figure 1.
