The device connects to typical transimpedance amplifiers (TIAs) that are AC-coupled. The linear signal output from TIAs can contain significant amounts of noise and may vary in amplitude over time. The SY88343BL quantizes these signals and outputs CML-level waveforms. The SY88343BL operates from a single +3.3V power supply, over temperatures ranging from –40 oC to +85oC. With its wide bandwidth and high gain, signals with data rates up to 3.2Gbps and as small as 5mVPP can be amplified to drive devices with CML inputs or AC- coupled CML/PECL inputs. The SY88343BL generates a high-gain loss-of-signal (LOS) open-collector TTL output. The LOS function has a high gain input stage for increased sensitivity. A programmable loss-of-signal level set pin (LOSLVL) sets the sensitivity of the input amplitude detection. LOS asserts high if the input amplitude falls below the threshold set by LOSLVL and de-asserts low otherwise. The enable bar input (/EN) de-asserts the true output signal without removing the input signal. The LOS output can be fed back to the /EN input to maintain output stability under a loss-of-signal condition. Typically, 3.5dB LOS hysteresis is provided to prevent chattering. Datasheet and support documentation can be found on Micrel’s web site at: www.micrel.com.
