FEATURES

■ Four programmable output banks and 15 total

LVPECL-compatible differential outputs

Precision Edge

■ Pin-compatible, plug-in replacement to

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

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
