SY88993AV中文资料Limiting Amplifiers数据手册Microchip规格书

描述 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
