SY89852U
Overview
The SY89852U is a 2.5V/3.3V precision, highspeed, 2:1 differential MUX capable of handling clocks up to 2.5GHz and data streams up to 2.5Gbps. The differential input includes Micrel’s unique, patent pending 3-pin input termination architecture that allows users to interface to any differential signal (AC- or DC-coupled) as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path.
- Provides a low jitter copy of the selected input
- Superior alternative to the EP58 2:1 MUX
- Low power: 58mW (2.5V nominal, no load)
- Guaranteed AC performance over temperature and supply voltage: - DC- to > 2.5Gbps data rate throughput - DC- to > 2.5GHz clock fMAX - < 340ps In-to-Out tpd - < 180ps tr/tf time
- Ultra-low Jitter Design: - <1ps(rms) random jitter - <10ps(pp) deterministic jitter - <10ps(pp) total jitter (clock) - <0.7ps(rms) crosstalk induced jitter
- Unique, patent-pending input isolation design minimizes crosstalk
- Unique, patent pending input termination and VT pin accepts DC-coupled and AC-coupled inputs (CML, PECL, LVDS)
- Typical 800mV (100k) LVPECL output swing
- Power supply 2.5V +5% or 3.3V +10%
- Industrial temperature range -40oC to +85oC
