SY88313BL

SY88313BL 3.3V, 3.2Gbps CML Low-Power Limiting Post Amplifier with TTL Loss-of-Signal General Description Features The SY88313BL low-power limiting post amplifier is Single 3.3V power supply designed for use in fiber-optic receivers. The device DC to 3.2Gbps operation connects to typical transimpedance amplifiers (TIAs). The linear signal output from TIAs can contain Low-noise CML data outputs significant amounts of noise and may vary in amplitude Chatter-free Open-Collector TTL loss-of-signal over time. The SY88313BL quantizes these signals and (LOS) output with internal 4.75kΩ pull-up outputs CML-level waveforms. resistor The SY88313BL operates from a single +3.3V ±10% TTL /EN input supply, over temperatures ranging from –40°C to +85°C. Internal 50Ω input termination With its wide bandwidth and high gain, signals with data rates up to 3.2Gbps, and as small as 10mVPP, can be Programmable LOS level set (LOSLVL) amplified to drive devices with CML inputs or AC Ideal for multi-rate applications coupled CML/PECL inputs. Available in a tiny 10-pin EPAD MSOP and The SY88313BL generates a loss-of-signal (LOS) open16-pin MLF® package collector TTL output. A programmable loss-of-signal level set pin (LOSLVL) sets the sensitivity of the input Applications amplitude detection. LOS asserts high if the input APON/BPON, GEPON, EPON, and GPON amplitude falls below the threshold set by LOSLVL and www.DataSheet4U.com Gigabit Ethernet de-asserts low otherwise. The enab...
