PIN CONFIGURATION
DESCRIPTION
The SY88993AV limiting post amplifier with its high 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 4mVp-p can be amplified to drive devices with
CML inputs or AC coupled PECL inputs. The SY88993AV
generates a chatter-free Loss of Signal (LOS) open collector
TTL output.
The SY88993AV incorporates a programmble level detect
function to identify when the input signal has been lost.
This information can be fed back to the /EN input of the
device to maintain stability under loss of signal conditions.
Using LOSLVL pin the sensitivity of the level detect can be
adjusted. The LOSLVL voltage can be set by connecting a
resistor divider between VCC and VREF, Figure 3.
