General Description
The SY89113U is a 2.5V low jitter, low skew, 1:12
LVDS fanout buffer optimized for precision telecom
and enterprise server distribution applications. The
input includes a 2:1 MUX for clock switchover
applications. Unlike other multiplexers, this input
includes a unique isolation design that minimizes
channel-to-channel
crosstalk.
The
SY89113U
distributes clock frequencies from DC to >1GHz
guaranteed
over
temperature
and
voltage.
The
SY89113U incorporates a synchronous output enable
(EN) so that the outputs will only be enabled/disabled
when they are already in the LOW state.
CLK0 differential input includes Micrel's unique, 3-pin
input termination architecture that directly interfaces 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.
CLK1 differential input includes a new version of
Micrel's unique, Any-Input architecture that directly
interfaces
with
single-ended
TTL/CMOS
logic
(including
3.3V
logic),
single-ended
LVPECL,
differential (AC- or DC-coupled) LVDS, HSTL, CML,
and LVPECL logic levels as small as 200mV
(400mVPP). CLK1 input requires external termination.
LVDS output swing 325mV into 100
with extremely
fast rise/fall time guaranteed to be less than 250ps.
The SY89113U operates from a 2.5V±5% supply and
is guaranteed over the full industrial temperature
range of -40°C to +85°C. The SY89113U is part of
Micrel's high-speed, Precision Edge
product line.
