MC100E196FNR2G

The MC10E/100E196 is a programmable delay chip (PDC) designed primarily for very accurate differential ECL input edge placement applications.The delay section consists of a chain of gates and a linear ramp delay adjust organized. The first two delay elements feature gates that have been modified to have delays 1.25 and 1.5 times the basic gate delay of approximately 80 ps. These two elements provide the E196 with a digitally-selectable resolution of approximately 20 ps. The required device delay is selected by the seven address inputs D[0:6] which are latched on chip by a high signal on the latch enable (LEN) control.The FTUNE input takes an analog voltage and applies it to an internal linear ramp for reducing the 20 ps resolution still further. The FTUNE input is what differentiates the E196 from the E195.An eighth latched input, D7, is provided for cascading multiple PDC's for increased programmable range. The cascade logic allows full control of multiple PDC's, at the expense of only a single added line to the data bus for each additional PDC, without the need for any external gating.The V pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to V as a switching reference voltage. V may also rebias AC coupled inputs. When used, decouple Vand V via a 0.01 5F capacitor and limit current sourcing or sinking to 0.5 mA. When not used, V should be left open. The 100 Series contains temperature compensation.
