Frequency Multiplier (CED)


The CED 4401 is designed for use in locking the sampling clock of a CED 1401 data acquisition unit to an external reference frequency, such as those encountered in other sampling systems. Suitable inputs are TTL signals that are stable sub-multiples of 20 MHz. The CED 4401 takes this frequency and multiplies it up to the 20 MHz needed to feed the external synchronising input of a CED 1401. The power LED on the CED 4401 turns from red to green when a usable input frequency is detected.

Case size: 126 mm × 104 mm × 53 mm (W × D × H) excluding connectors and power supply.

Power supply: 100 – 240V AC mains input 50 – 60 Hz, 9V DC output.
