General Description
The SY89465U is a low-jitter, 1:10 LVDS fanout
buffer with a 2:1 differential input multiplexer (MUX)
optimized
for
redundant
source
switchover
applications. Unlike standard multiplexers, the
SY89465Us 2:1 Runt Pulse Eliminator (RPE) MUX
prevents any short cycles or “runt” pulses during
switchover. In addition, a unique Fail-Safe Input
(FSI) protection prevents metastable conditions
when the selected input clock fails to a DC voltage
(voltage between the pins of the differential input
drops below 100mV).
The differential input includes Micrel’s, 3-pin internal
termination architecture that allows customers 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. The outputs are LVDS-compatible with
fast rise/fall times guaranteed to be less than 220ps.
The SY89465U operates from a 2.5V ±5% supply
and
is
guaranteed
over
the
full
industrial
temperature range of –40°C to +85°C. The
SY89465U is part of Micrel’s high-speed, Precision
Edge
product line.
