MC100EP196
3.3VECL 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 VCC to VEE 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.
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 VEF (pin 7) and VCF (pin 8)
for LVCMOS, ECL, or LVTTL level signals. LVTTL and LVCMOS
operation is available in PECL mode only. 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 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.
