SY89855U
Precision Low Power Differential LVPECL 4:1
MUX with 1:2 Fanout and Internal
Termination General Description
The SY89855U is a 2.5V/3.3V precision, high-speed,
4:1 differential multiplexer with 100K LVPECL (800mV)
compatible outputs, capable of handling clocks up to
2.5GHz and data streams up to 2.5Gbps. In addition, a
1:2 fanout buffer provides two copies of the selected
inputs.
The differential input includes Micrel’s unique, 3-pin
input termination architecture that allows customers to
interface to any differential signal (AC-or DC-coupled)
as small as 100mV without any level shifting or
termination resistor networks in the signal path. The
result is a clean, stub-free, low-jitter interface solution.
The outputs are 800mV LVPECL, (100K temperature
compensated) with fast rise/fall times guaranteed to be
less than 180ps.
The SY89855U operates from a 2.5V В±5% supply or a
3.3V В±10% supply and is guaranteed over the full
industrial temperature range of –40°C to +85°C. For
applications that require higher performance, consider …
