DESCRIPTION
The SY88993V 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. The SY88993V generates a chatter-free Loss
of Signal (LOS) open collector TTL output.
The SY88993V 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 LOS
LVL
pin the sensitivity of the level detect can be
adjusted. The LOS
LVL
voltage can be set by connecting a
resistor divider between V
CC
and V
