3.3VꢀECL Programmable

Delay Chip with FTUNE

The MC100EP196 is a programmable delay chip (PDC) designed

primarily for clock deskewing and timing adjustment. It provides variable

delay of a differential NECL/PECL input transition. It has similar

architecture to the EP195 with the added feature of further tuneability in

delay using the FTUNE pin. The FTUNE input takes an analog voltage

from V to V to fine tune the output delay from 0 to 60 ps.

The delay section consists of a programmable matrix of gates and

multiplexers as shown in the logic diagram, Figure 2. The delay increment

of the EP196 has a digitally selectable resolution of about 10 ps and a net

range of up to 10.2 ns. The required delay is selected by the 10 data select

inputs D[9:0] values and controlled by the LEN (pin 10). A LOW level on

LEN allows a transparent LOAD mode of real time delay values by

D[9:0]. A LOW to HIGH transition on LEN will LOCK and HOLD

current values present against any subsequent changes in D[10:0]. The

approximate delay values for varying tap numbers correlating to D0 (LSB)

through D9 (MSB) are shown in Table 5.

CASE 873A

Because the EP196 is designed using a chain of multiplexers, it has a

fixed minimum delay of 2.4 ns. An additional pin, D10, is provided for

controlling Pins 14 and 15, CASCADE and CASCADE, also latched

by LEN, in cascading multiple PDCs for increased programmable

range. The cascade logic allows full control of multiple PDCs.

Switching devices from all “1” states on D[0:9] with SETMAX LOW

to all “0” states on D[0:9] with SETMAX HIGH will increase the

delay equivalent to “D0”, the minimum increment.

Select input pins, D[10:0], may be threshold controlled by

combinations of interconnects between V (pin 7) and V (pin 8)

for LVCMOS, ECL, or LVTTL level signals. LVTTL and LVCMOS

operation is available in PECL mode only. For LVCMOS input levels,

leave V and V open. For ECL operation, short V and V

(pins 7 and 8). For LVTTL level operation, connect a 1.5 V supply

reference to V and leave open V pin. The 1.5 V reference voltage

to V pin can be accomplished by placing a 2.2 kW resistor between

and V for 3.3 V power supply.

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.

may also rebias AC coupled inputs. When used, decouple V

and V via a 0.01 mF 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.
