DESCRIPTION  
MC100LVE222FA  
f  
clock = 1.5GHz  
MAX  
The SY100E222L is a low-skew, low-jitter device capable  
of receiving a high-speed LVECL/LVPECL input in either a  
single-ended or differential configuration. For single-ended  
50ps output-to-output skew  
Four output banks with independent ÷1, ÷2  
frequency control  
configurations, a V  
output reference is supplied by the  
BB  
SY100E222L. A 2:1 input multiplexer selects from two  
differential input pairs by means of the CLK_SEL input select.  
100k compatible I/O  
Power supply 3.3V ±10%  
The internal programmable divider for each of the four  
banks generates a ÷1 or ÷2 frequency of the selected input.  
The ÷1/÷2 divider outputs can be asynchronously  
synchronized with the master reset (MR) input so that the  
outputs will start out in a known state.  
–40°C to +85°C temperature range  
Available in 52-pin LQFP package  
APPLICATIONS  
The 15 total outputs are partitioned into four independently  
selected output banks in a 2/3/4/6 fanout configuration. Each  
of the four banks can independently select the ÷1 or ÷2  
output frequency by means of the four separate frequency  
select pins (FSELA-FSELD) inputs.  
SONET/SDH channel applications  
Fibre Channel multi-channel applications  
Gigabit Ethernet multi-channel applications
