Delay Chip
Descriptions
The MC100EP195B 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.
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 EP195B 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
The IN/IN inputs can accept LVPECL (SE of Diff), or LVDS level
signals. Because the EP195B is designed using a chain of multiplexers
it has a fixed minimum delay of 2.2 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 VEF (pin 7) and VCF (pin 8)
for LVCMOS, ECL, or LVTTL level signals. For LVCMOS input
levels, leave VCF and VEF open. For ECL operation, short VCF and
VEF (Pins 7 and 8). For LVTTL level operation, connect a 1.5 V
supply reference to VCF and leave open VEF pin. The 1.5 V reference
voltage to VCF pin can be accomplished by placing a 2.2 kW resistor
between VCF and VEE for a 3.3 V power supply.
The VBB pin, an internally generated voltage supply, is available to
this device only. For singleended input conditions, the unused
differential input is connected to VBB as a switching reference voltage.
VBB may also rebias AC coupled inputs. When used, decouple VBB
and VCC via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, VBB should be left open.
The 100 Series contains temperature compensation.
