SY10E157JY-TR Application Field and Working Principle

The SY10E157JY-TR is a low-power, high-performance low skew 1-of-10 Differential-to-LVCMOS/LVTTL Clock Driver. This device falls into the logic-signal switches, multiplexers, and decoders category, and is designed to convert a single low-voltage differential signal (LVDs) to ten LVCMOS/LVTTL outputs. The device also provides excellent jitter performance and low noise.

Device Overview

The SY10E157JY-TR device is a low-power, high-performance, low-skew 1-of-10 differential-to-LVCMOS/LVTTL clock driver. The device has two inputs: a differential LVDs signal (DIF0 and DIF1) and a control input (CTL), and ten differential outputs (D0 - D9). The device can be used to convert a single low-voltage differential signal (LVDs) to 10 LVCMOS/LVTTL outputs.The SY10E157JY-TR device has a wide operating range of between 2.5V to 3.3V. It is specified for a temperature range of -40°C to +85°C. The device has a high-speed output rise time of 5 ns and a maximum propagation delay of 11 ns. It has a low-skew of 400 ps and a low-input-jitter sensitivity of 3 ps. The device supports load capacitance up to 20pF. It has a typical power consumption of 5mW.

Application Field

The SY10E157JY-TR device is ideal for 1-of-10 differential clock fan-out applications. It is designed to be used in clock distribution networks in high-speed communication systems, such as in switches, routers, and ASIC/FPGA circuits. It is also suitable for computing and other data-intensive applications that require low jitter and low skew.

Working Principle

The SY10E157JY-TR device is designed to convert a single low-voltage differential signal (LVDs) to ten LVCMOS/LVTTL outputs. The device is powered by a single 2.5 to 3.3V supply. The LVDs signal is first converted to a single-ended signal and then buffered by a low-power, high-performance latch. This latch is used to drive the clock output buffers. The clock output buffers have the necessary skews and have the ability to drive heavily loaded loads.The device also contains Low-to-High (LH) and High-to-Low (HL) daisy-chain skew-adjustment blocks. These blocks can be used to reduce the output-to-output jitter and to ensure that the propagated clock signals have the same frequency.The device also contains a CTL input pin, which is used to select the LVDs signal. The CTL input pin can be tied to either VCC or GND, depending on the chosen output frequency.

Conclusion

The SY10E157JY-TR is a low-power, high-performance low skew 1-of-10 Differential-to-LVCMOS/LVTTL Clock Driver that falls into the Logic-Signal Switches, Multiplexers, and Decoders category. It is an ideal device for 1-of-10 differential clock fan-out applications in high-speed communication systems. It has a wide operating range, a fast output rise time, and a low-skew and low-input-jitter sensitivity. The device is powered by a single 2.5 to 3.3V supply, and supports load capacitance up to 20pF.
