Author Topic: Freq. counter DSI Model 5600A  (Read 7497 times)

Posts: 7

« on: April 19, 2013, 02:32:59 PM »

My counter , the 5600A , long time agoo made by DSI has a pre-scaled input . It was told that DSI was a company in San Diego .
There is a divider used and this is a DS1020 chip . It is a 8 pin IC and I am looking for the data of this IC .
There are only delay lines given when I google for ther DS1020 .
So my question ... is there anyone who can help me with data of this IC ? Perhaps in US it is easier to get info about this device . Who can help an amateur out of the little Netherlands ? I would be very glad to get some info .
Thank you so much .. also e-mail possible to :
( excuses for my poor english , hi )

Maxim Integrated acquired Dallas Semiconductor, original mfg. of the DS1020 a few years ago.
All Dallas/Maxim DS1020 versions are No Longer Available (NLA).  Recommended Replacements: Maxim DS1023 or DS1123L

Dallas / Maxim DS1020 Data Sheet

The DS1020 is an 8-bit programmable delay line that reproduces an input logic state at the output after a user-programmed delay. Delays can be varied over 256 steps with resolutions of 0.15ns, 0.25ns, 0.50ns, 1.0ns, or 2.0ns (see table). Total delays range from an inherent 10ns minimum delay to a maximum 520ns. The DS1020 is programmed over the 3-wire serial port or the 8-pin parallel port. The DS1020 is TTL- and CMOS-compatible, and capable of driving up to ten 74LS-type loads. Both leading- and trailing-edge accuracy are specified.

The DS1020 is an effective, economical solution to the designer working with the complex timing requirements of mismatched ASICs or other components, or with the strict timing tolerances of increasing system clock rates. With the DS1020's programmable outputs, the user can precisely adjust timing to application needs and improve system performance. Innovative circuit designs and factory laser or EPROM trimming enhance accuracy without the need for external components, saving cost and space.

dr W9GB
there is something strange .... The DS 1020 is used as the pre-scaler in my counter .
And it is a 8 pin dual in line little chip .
Also I see only data of delay-lines .. so I do not understand this .
But .. of course thank you vy much for your reaction and information .
I do not think that a delay-line can be used as a pre-scaler , or .. am I wrong ?
