Signals as small as 4m Vp-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.
