DELAY CHIP  
SY100E195  
FEATURES  
DESCRIPTION  
Up to 2ns delay range  
The SY10/100E195 are programmable delay chips  
(PDCs) designed primarily for clock de-skewing and timing  
adjustment. They provide variable delay of a differential  
ECL input transition.  
The delay section consists of a chain of gates  
organized as shown in the logic diagram. The first two  
delay elements feature gates that have been modified to  
have delays 1.25 and 1.5 times the basic gate delay of  
approximately 80ps. These two elements provide the  
Extended 100E VEE range of –4.2V to –5.5V  
20ps/digital step resolution  
>1GHz bandwidth  
On-chip cascade circuitry  
75Kkinput pulldown resistor  
Fully compatible with Motorola MC10E/100E195  
Available in 28-pin PLCC package  
E195 with  
a
digitally-selectable resolution of  
approximately 20ps. The required device delay is selected  
by the seven address inputs D[0:6], which are latched  
on-chip by a high signal on the latch enable (LEN) control.  
If the LEN signal is either LOW or left floating, then the  
latch is transparent.  
Because the delay programmability of the E195 is  
achieved by purely differential ECL gate delays, the  
device will operate at frequencies of >1GHz, while  
maintaining over 600mV of output swing.  
The E195 thus offers very fine resolution, at very high  
frequencies, selectable entirely from a digital input,  
allowing for very accurate system clock timing.  
An eighth latched input, D7, is provided for cascading  
multiple PDCs for increased programmable range. The  
cascade logic allows full control of multiple PDCs, at the  
expense of only a single added line to the data bus for  
each additional PDC, without the need for any external  
gating.
