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 fano.
The SY100E222L provides a programmable clock generator and fan‑out buffer capable of handling 3.3 V LVPECL/LVECL signals up to 1.5 GHz. It features four independent output banks, each selectable for +1 or +2 frequency multiplication, and delivers 15 LVPECL‑compatible differential outputs in a 2/3/4/6 fan‑out configuration. The device is pin‑compatible with the MC100LVE222FA and belongs to Micrel’s Precision Edge® product family.
The part is supplied in a 52‑pin LQFP package and operates from a 3.3 V supply (+10 %). Electrical specifications include a supply voltage range of –0.5 V to +4.0 V, maximum operating frequency above 1.5 GHz, typical propagation delay of about 1.2 ns (differential) and a within‑device skew of 50 ps. It is rated for –40 °C to +85 °C operation and includes detailed pin descriptions, absolute maximum ratings, and AC/DC electrical characteristics.
