EDGE HIGH-PERFORMANCE PRODUCTS
Circuit Description
Chip Overview
The Edge118 is a clock distribution chip designed to
take one input signal (IN / IN*) and fan it out 18 times
to identical outputs (OUT / OUT*). The chip is designed
to minimize channel to channel skew and any timing jitter.
The parts wide fanout is extremely useful in applications
where many distinct copies of a signal are required on
one PC Board, and these signals must all be aligned.
This signal can be distributed without creating a
distribution tree using multiple devices.
Inputs
The input signal is differential, requiring 250 mV swings
for full performance operation. The inputs are ECL
compatible, but may also be operated over a common
mode voltage range between VEE + 1.3V and VCC .5V.
Outputs
The outputs are ECL compatible differential signals with
800 mV voltage swings centered around 1.3V below GND.
IN
IN*
Operating Frequency
The Edge118 is designed to maintain full performance
up to at least 1000 MHz and pass 500 ps pulses.

Notes:
1. All dimensions and tolerances conform to ANSI Y14.5-1982.
2. Datum plane -H- located at mold parting line and coincident with lead,
where lead exits plastic body at bottom of parting line.
3. Datums A-B and -D- to be determined at centerline between leads where
leads exit plastic body at datum plane -H-.
4. To be determined at seating plane -C-.
5. Dimensions D1 and E1 do not include mold protrusion. Allowable mold
protrusion is 0.254 mm per side. Dimensions D1 and E1 do
include mold mismatch and are determined at datum plane -H.-.
6. Nis the total # of terminals.
7. Package top dimensions are smaller than bottom dimensions by
0.20 mm, and top of package will not overhang bottom of package.
8. Dimension b does not include dambar protrusion. Allowable dambar
protrusion shall be 0.08mm total in excess of the b dimension at
maximum material condition. Dambar cannot be located on the lower
radius or the foot.
9. All dimensions are in millimeters.
10. Maximum allowable die thickness to be assembled in this package family
is 0.635 millimeters.
11. This drawing conforms to JEDEC registered outlines MO-108 and
MS-022.
12. These dimensions apply to the flat section of the lead between 0.10 mm
and 0.25 mm from the lead tip.
