BGA (HE) Delay Lines (Patent Pending)
HE2LA(A,B)A***D
Series
Description
High-efficiency delay lines for clock and data deskew in differential circuit
designs requiring precise timing control in a small, low profile BGA
package. The differential delay lines are constructed as broadside-coupled
transmission lines on ceramic. These designs feature characteristics similar
to unshielded twisted-pair cable.
This product is currently available with solder finshes of Sn63/Pb37, as well
as a RoHS compliant, Pb free solder finish of Sn95.5/Ag3.8/Cu0.7. For the
RoHS compliant part, the customer must specify this upon ordering by
following the instructions in the part numbering section of this specification.

Mechanical
Size A
Notes:
Delay Line 1 I/O (DL1) = b1 & b3
Delay Line 2 I/O (DL2) = c1 & c3
The following positions do not have a ball: a1, a3, b2,
c2, d1, d3
No Connection = all other
Both signals shall enter positions '1' and exit positions
'3' or both signals shall enter positions '3' and exit
positions '1'.
Size B
Notes:
Delay Line 1 I/O (DL1) = a2 & b2
Delay Line 2 I/O (DL2) = a3 & b3
No Connection = all other
Both signals shall enter positions 'a' and exit positions
'b' or both signals shall enter positions 'b' and exit
positions 'a'.
Notes for Both:
Either DL1 or DL2 can be used for the inv. and non-inv.
signals.
Ball positions labeled 'No Connection' are only present
for mechanical stability (attach all to open pads on
board).
