DS1100U-35+

DS1100U-35+ application field and working principleThe DS1100U-35+ is an integrated delay line that belongs to the clock/timing category and its field of application involves telecommunications, radar and sonar systems, and GPS guidance systems. This device is a monolithic device which provides a finely controlled and adjustable linear delay feature over a frequency range from DC to 500 MHz. The DS1100U-35+ has a differential gain and phase balance of the generically symmetrical input and output ports, and it is operated with a single voltage supply of 2.7V to 5.5V. It typically provides a differential delay line of up to about 35ns max. This device’s working principle involves a hybrid technology which integrates several components in a single system. It is described as a reciprocal combination of a capacitor-loaded distributed line and a Gilbert multiplier which acts as its building block. The capacitor-loaded distributed line serves as an intentional distributed network in the device and it provides a programmable delay while the Gilbert multiplier is an amplifier with two analog multipliers and two input ports. The two inputs of the Gilbert multiplier introduce an additional path in the device and can be used to tailor the signal within the device. Furthermore, the integrated delay line also has out of band signal rejection capabilities and software programmable delay which is achieved through the two input ports of the Gilbert multiplier. The output of the delay line’s amplifier is signal level independent with a unified charge pump. The combination of the capacitor-loaded distributed line and the Gilbert multiplier works together to enable the DS1100U-35+ to have a variable delay in the signal and differential gain or frequency independent gain or phase. This integrated delay line also operates with low propagation delay and low insertion loss, making it an effective device for telecommunications, radar and sonar systems and GPS guidance systems. As such, the DS1100U-35+ integrated delay line is an efficient integrated device for clock/timing devices for various applications. The combination of its distributed line and multiplier technology allows for adjustable linear delay, low propagation latency and low insertion loss, and its differential gain and phase balance effectively balances and amplifies the signals within the device. With the integrated delay line’s features, it is a reliable choice for various telecommunications, radar and sonar systems, and GPS guidance systems.
