GENERAL DESCRIPTION
The SY84403BL quantizes these signals and outputs typically 800mVPP voltage-limited waveforms. The SY84403BL comes in a tiny 10-pin 2x2 MLF® package, which is unparalleled in the industry. It offers space savings of 55% or more over typical post amps. It operates from a single +3.3V ±10% power supply, over an industrial temperature range of –40°C to +85°C. With its wide bandwidth and high gain, signals with data rates up to 4.25Gbps and as small as 10mVPP can be amplified to drive devices with CML inputs or AC-coupled PECL inputs. The SY84403BL incorporates a loss-of-signal (LOS) open-collector TTL output with internal 4.75kΩ pull-up resistor. 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. LOS can be fed back to the enable bar (/EN) input to maintain output stability under a loss of signal condition. /EN de-asserts the true output signal without removing the input signal.
