ICS1574BM is a low pin count, self-contained clock and data recovery (CDR) device designed to recover and generate a fast serial clock signal and data from a noisy input data stream. The device is designed to support many serial communication protocols, such as Fibre Channel, Serial ATA, 10 Gigabit Ethernet, and other serial bit-rate services. The device provides a high-speed serial link with minimal propagation delay over a wide range of temperatures, operating across a wide range of supply voltages, and capable of supporting data rates up to 10 Gbps. It comes with a wide range of features and options, including integrated analog PLL, phase-lock loop (PLL), phase interpolator, integrated frequency synthesizer, clock multiplication, and logic buffer functions.

The ICS1574BM is a highly integrated HDI DRAM link clock recovery IC that supports serial data rates up to 10 Gbps. It provides a single-ended or differential clock output source to sink synchronization clock and data signals. The device eliminates the need for external crystal oscillators and extra logic support for the clock recovery process. Internally, the ICS1574BM consists of a high-precision analog phase-locked loop (PLL) circuit, an integrated frequency synthesizer, a multi-phase clock generator, and a multi-phase clock buffer. The PLL circuit is used to recover the clock signal from the input data stream and the frequency synthesizer uses the recovered clock signal to generate a stable clock signal. The PLL circuit has an operating range of up to 10 Gbps and is capable of recovering data rates of up to 10 Gbps.

The ICS1574BM is designed to offer the flexibility and control necessary for high-end server applications. The device supports a wide range of output frequencies, from 156.25 MHz to 320 MHz, to enable the system clock rate for high-end communications and storage applications.The output frequency of the ICS1574BM can be adjusted by fine-tunning the onboard PLL and by dynamically scaling the output frequency over a wide range. In addition, the ICS1574BM provides integrated logic support for high-speed signal error detection, data valid and logic signaling protection, and enhanced jitter filtering.

To ensure reliable operation, the ICS1574BM supports various features such as integrated Intel P5 core processor interface, on-board temperature sensors, and delay-locked loop output. The processor interface allows system designers to tune the clock signal to minimize jitter and minimize bit error rate over the data channel. The delay-locked loop output allows users to adjust the duty cycle of the signal to minimize clock skew.

The ICS1574BM’s usage extends beyond clock recovery applications, as it can also be used in a variety of clock generation applications. This makes it a suitable choice for clock distribution, clock and data regeneration, and system timing applications. The ICS1574BM has also been successfully used in high-end server applications as a low-cost, low-power clock solution.

In conclusion, the ICS1574BM is an ideal device for applications requiring high speed data rate, low latency, and low jitter clock signal. It offers excellent precision, wide temperature range, and reliable operation. With its integrated features, it is suitable for a variety of clock applications, such as clock recovery, clock synthesis, and clock distribution. In particular, the ICS1574BM has been proven in high-end server applications.
