DESCRIPTION
Precision Edge™
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
configurations, a VBB output reference is supplied by the
SY100E222L. A 2:1 input multiplexer selects from two
differential input pairs by means of the CLK_SEL input select.
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.
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.
Thewww.DataSheet4U.com SY100E222L is pin-for-pin compatible with the
MC100LVE222FA device.
The SY100E222L is part of a Micrel’s Precision Edge™
product family. For other integrated clock divider plus fanout
buffer options, consider Micrel’s SY89200 family.
All support documentation can be found on Micrel’s web
site at www.micrel.com.
