SY88315BL

SY88315BL 3.3V, 3.2Gbps CML Low-Power Limiting Post Amplifier w/TTL Signal Detect General Description Features Single 3.3V power supply The SY88315BL low-power limiting post amplifier is designed for use in fiber-optic receivers. The device DC to 3.2Gbps operation connects to typical transimpedance amplifiers (TIAs). Low-noise CML data outputs The linear signal output from TIAs can contain Chatter-free Open-Collector TTL signal detect (SD) significant amounts of noise and may vary in amplitude output with internal 4.75kΩ pull-up resistor over time. The SY88315BL quantizes these signals and TTL EN input outputs CML level waveforms. Internal 50Ω input termination The SY88315BL operates from a single +3.3V +10% o power supply, over temperatures ranging from –40 C to Programmable SD level set (SDLVL) +85oC. With its wide bandwidth and high gain, signals Ideal for multi-rate applications with data rates up to 3.2Gbps and as small as 10mVPP Available in a tiny 10-pin EPAD MSOP and 16-pin can be amplified to drive devices with CML inputs or ACMLF® package coupled CML/PECL inputs. The SY88315BL generates a signal-detect (SD) openApplications collector TTL output. A programmable signal-detect level APON/BPON, EPON, and GPON set pin (SDLVL) sets the sensitivity of the input amplitude detection. SD asserts high if the input amplitude rises Gigabit Ethernet above the threshold set by SDLVL and de-asserts low Fibre Channel otherwise. The enable input (EN) de-ass...
