D[9:0]
CMOS, ECL, or TTL Control Bits: These control signals adjust the delay from IN to Q.
See
“
AC Electrical Characteristics
”
for delay values. In addition, see
“
Interface Applications
”
section which illustrates the proper interfacing techniques for different logic standards.
D[9:0] contains pull-downs and defaults LOW when left floating. D0 (LSB), and D9 (MSB).
See
“
Typical Operating Characteristics
”
for delay information.

D10
CMOS, ECL, or TTL Control Bit: This bit is used to cascade devices for an extended delay
range. In addition, it drives CASCADE, and /CASCADE. Further, D[10] contains a pull-
down and defaults LOW when left floating.
LVPECL/ECL Signal Input: Input signal to be delayed. IN contains a 75k
pull-down and
will default to a logic LOW if left floating.

VBB
(1)
Reference Voltage Output: When using a single-ended input signal source to IN or /IN,
connect the unused input of the differential pair to this pin. This pin can also be used to
rebias AC-coupled inputs to IN and /IN. When used, de-couple to V
CC
using a 0.01

capacitor, otherwise leave floating if not used. Maximum sink/source is
±
0.5mA.
Reference Voltage Output: Connect this pin to V

LEN
ECL Control Input: When HIGH latches the D[9:0] and D[10] bits. When LOW, the D[9:0]
and D[10] latches are transparent.
11
SETMIN
ECL Control Input: When HIGH, D[9:0] registers are reset. When LOW, the delay is set
by SETMAX or D[9:0] and D[10]. SETMIN contains a pull-down and defaults LOW when
left floating.

SETMAX
ECL Control Input: When SETMAX is set HIGH and SETMIN is set LOW, D[9:0] =

b1111111111. When SETMAX is LOW, the delay is set by SETMIN or D[9:0] and
D[10]. SETMAX contains a pull-down and defaults LOW when left floating.

LVPECL Differential Output: The outputs are used when cascading two or more
SY89295U to extend the delay range.

/EN
LVPECL Single-Ended Control Input: When LOW, Q is delayed from IN. When HIGH,
Q is a differential LOW. /EN contains a pull-down and defaults LOW when left floating.
