Renesas Electronics Corporation

Renesas’ Timing product portfolio has been acquired by SiTime.

Datasheets, documentation, and sample orders remain available on Renesas.com through late 2026. For new designs, purchasing, support, and product inquiries, visit SiTime.com or send an email to SalesClocks@sitime.com. Full transition to SiTime is expected by late 2026.

Description

The IDT570 is a high-performance Zero Delay Buffer (ZDB) which integrates IDT's proprietary analog/digital Phase Locked Loop (PLL) techniques. The A version is recommended for 5 V designs and the B version for 3.3 V designs. The chip is part of IDT's ClockBlocks™ family, and was designed as a performance upgrade to meet today's higher speed and lower voltage requirements. The zero delay feature means that the rising edge of the input clock aligns with the rising edges of both output clocks, giving the appearance of no delay through the device. There are two outputs on the chip, one being a low-skew divide by two of the other output. The device incorporates an all-chip power down/tri-state mode that stops the internal PLL and puts both outputs into a high impedance state. The IDT570 is ideal for synchronizing outputs in a large variety of systems, from personal computers to data communications to graphIDT/video. By allowing off-chip feedback paths, the device can eliminate the delay through other devices.

  1. Info about H8/570 ISP

    I'm looking for a specific document regarding the H8/570 16-bit MCU. The document is called "ISP Hardware Manual", which should explain how the ISP (Intelligent Sub Processor) is supposed to work. Is it available anywhere?
