DS1004Z-2+T is a clock or timing-delay line product developed and produced by Shanghai DaiSi Electronic Technology Co., Ltd. It was developed based on a patented technology which can provide up to 20-fold improvement in signal propagation. It is suitable for applications ranging from consumer electronics, automotive, and aerospace to medical, military and industrial uses.

This product has been developed specifically for clock and timing applications. It is well-suited for on-chip or chip-to-chip synchronization applications, as well as time-of-flight measurements. Its advanced technology relies on total impedance matching along the signal path, providing improved latency and jitter performance. It can be used to minimize overall cable lengths, thus reducing cost and complexity.

The DS1004Z-2+T features a propagation delay of up to 20 nanoseconds. It has a wide temperature range of 0 - 70°C and can operate at low power (1.65V) without needing an external supply. The device includes built-in misalignment and skew protection, ensuring high levels of resistances of up to 8 kΩ. An internal I2C interface is also included, making it easier to configure the device.

The workings of the DS1004Z-2+T can be divided into two stages: the first is the propagation delay stage, which is responsible for increasing the signal propagation delay. The second stage is the delay line, which is responsible for buffering and balancing the direct clock transition interference.

The propagation delay is achieved by controlling the total impedance matching along the signal path. A series of interleaved resistors and capacitors form an effective impedance line, which reduces the high frequency components of the input signal into a low-frequency signal. This low-frequency signal is then passed to the delay line, where it is amplified and sent to the output port. The delay line is composed of parallel spaced buffer elements that amplify and output the clock signals.

The DS1004Z-2+T is ideal for applications that require a precise synchronization or precise time-of-flight measurements. Its wide temperature range ensures reliable operation in extreme temperatures, while its low power operating requirement and built-in misalignment and skew protection makes it suitable for all manner of power-sensitive designs. The device includes an I2C interface, which makes it easier to configure the device. Finally, its advanced technology allows for improved latency and jitter performance in clock/timing applications.
