Precision Edge 3.3V, 1.5GHz 1/2 DIFFERENTIAL Micrel, Inc. SY100E222L Precision Edge LVECL/LVPECL PROGRAMMABLE CLOCK SY100E222L GENERATOR AND 1:15 FANOUT BUFFER 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 50ps output-to-output skew of receiving a high-speed LVECL/LVPECL input in either a Four output banks with independent 1, 2 single-ended or differential configuration. For single-ended frequency control configurations, a V output reference is supplied by the BB SY100E222L. A 2:1 input multiplexer selects from two 100k compatible I/O differential input pairs by means of the CLK SEL input select. Power supply 3.3V 10% The internal programmable divider for each of the four 40C to +85C temperature range banks generates a 1 or 2 frequency of the selected input. Available in 52-pin LQFP package The 1/2 divider outputs can be asynchronously synchronized with the master reset (MR) input so that the APPLICATIONS outputs will start out in a known state. The 15 total outputs are partitioned into four independently SONET/SDH channel applications selected output banks in a 2/3/4/6 fanout configuration. Each Fibre Channel multi-channel applications of the four banks can independently select the 1 or 2 Gigabit Ethernet multi-channel applications output frequency by means of the four separate frequency select pins (FSELA-FSELD) inputs. FUNCTIONAL BLOCK DIAGRAM The SY100E222L is pin-for-pin compatible with the MC100LVE222FA device. 1:2 FOB QA0 CLK SEL The SY100E222L is part of a Micrels Precision Edge /QA0 CLK0 1 product family.
