SY58038U
Description
The SY58038U is a low-jitter, low-skew, high-speed 8:1 multiplexer with a 1:2 differential fanout buffer optimized for precision telecom and enterprise server distribution applications. The SY58038U distributes clock frequencies from DC to 3.5GHz, and data rates to 4.5Gpbs guaranteed over temperature and voltage.
Key Features
- Selects between 1 of 8 inputs, and provides two precise, low-skew LVPECL output copies
- Ultra-low jitter design: - 72fsrms phase jitter (typical)
- Guaranteed AC performance over temperature and voltage: - DC to 4.5Gbps throughput - <500ps propagation delay IN-to-Q (VIN > 100mV) - <100ps tr / tf time - <15ps skew (output-to-output)
- Unique, patented, channel-to-channel isolation design provides superior crosstalk performance
- Unique, patented, input termination and VT pin accepts DC- and AC-coupled inputs (CML, PECL, LVDS)
- 800mV LVPECL output swing
- Power supply 2.5V ±5% or 3.3V ±10%
- -40°C to +85°C temperature range
- Available in 44-pin (7mm × 7mm) QFN packa
