New LeCroy ECLine Model 4518 Programmable Logic Delay/Fan-Out is a single-width CAMAC module. Fast, passive logic delays are important when signals must arrive simultaneously at a data acquisition module. The LeCroy Model 4518 has 16 passive, tapped delay lines, one for each input. Each delay is individually set by computer via CAMAC in 1, 2 or 8 nsec increments (depending on sub-model or "MOD" selected), over a range of fifteen increments. The selection directs an output to "use" a particular tap on the delay line. This would give a means of accurately aligning signals in time, for example, to compensate for differences in cable lengths.
Dead timeless operation at speeds up to 100 MHz is assured by using passive delay lines and ECL switches. This feature provides the reliability of cable delays together with the speed and fan-out of ECL circuitry. Each output is available three places on the front panel to provide fan-out. The cost of this device rivals cable delays.
