General Description
The SY89467U is a 2.5/3.3V, 1:20 LVPECL fanout
buffer with a 2:1 differential input multiplexer (MUX).
A unique Fail-Safe Input (FSI) protection prevents
metastable output conditions when the selected
input clock fails to a DC voltage (when voltage
between the pins of the differential input drops
significantly below 100mV).
The differential input includes Micrel’s unique, 3-pin
internal termination architecture that can 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 800mV, LVPECL with fast rise/fall times
guaranteed to be less than 270ps.
The SY89467U operates from a 2.5V ±5% or 3.3V
±10% supply and is guaranteed over the full
industrial temperature range of –40°C to +85°C. The
SY89467U is part of Micrel’s high-speed, Precision
Edge
product line.

Features
Selects between two inputs, and provides 20
precision LVPECL copies
Fail-Safe Input
– Prevents outputs from oscillating when input is
invalid
Guaranteed AC performance over temperature and
supply voltage:
– DC-to >1.5 GHz throughput
– < 1200ps Propagation Delay (In-to-Q)
– 270ps Rise/Fall times
Ultra-low jitter design:
– <1psRMS random jitter
– <1psRMS cycle-to-cycle jitter
– <10psPP total jitter (clock)
– <0.7psRMS MUX crosstalk induced jitter
Unique, patented MUX input isolation design
minimizes adjacent channel crosstalk
Unique patented internal termination and VT pin
accepts DC- and AC-coupled inputs (CML, PECL,
LVDS)
Wide input voltage range: V
CC to GND
2.5V ±5% or 3.3V ±10% supply voltage
-40°C to +85°C industrial temperature range
Available in 64-pin TQFP package
