DESCRIPTION
s Single 3.3V or 5V power supply
s Up to 3.2Gbps operation
s Low noise PECL data outputs
s Chatter-free open collector TTL LOS output
s TTL /EN Input
s Differential PECL inputs for data
s Available in a tiny 10-pin (3mm) MSOP and 10-pin
(3mm) EPAD-MSOP
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 5mV
PP 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
LOSLVL. This information can be fed back to the EN input
of the device to maintain stability under loss-of-signal
condition. Using LOSLVL pin, the sensitivity of the level
detection can be adjusted. The LOSLVL voltage can be set
by connecting a resistor divider between VCC and VREF
shown in Figure 3. “Typical Operating Characteristics” on
page 6 show the relationship between input level sensitivity
and the voltage set on LOSLVL.
The LOS output is a TTL open collector output that
requires a pull-up resistor for proper operation, Figure 1.
