MK2304S-2ITR

Overview

The MK2304S-2ITR is a zero-delay, low-skew buffer manufactured by Renesas Electronics Corporation (formerly IDT). It utilizes a Phase Lock Loop (PLL) to align the rising edge of the input clock with four outputs. The device provides two full-speed (1X) outputs and two half-speed (1/2X) outputs. Operating at 3.3V, it supports frequencies up to 133 MHz with a load of 15 pF. The component is housed in an 8-pin SOIC package and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Zero delay mode aligns input clock rising edges with all output rising edges
• Provides four outputs: two at 1X frequency and two at 1/2X frequency
• Output-to-output skew is less than 200 ps on the same bank
• Low standby current of less than 25 µA when inputs are inactive

Applications

• High-speed data acquisition systems requiring precise clock distribution
• Telecommunications equipment utilizing spread spectrum clocking
• Computer peripherals and high-performance digital logic interfaces

Procurement Notes

Verify that the specific order matches the industrial temperature grade (-40°C to +85°C) indicated by the 'I' suffix. Confirm the tape and reel packaging format corresponding to the 'TR' suffix for automated assembly compatibility. Ensure the design accounts for the legacy status of the original manufacturer, Integrated Device Technology, now part of Renesas.

Selection Notes

Select this component when zero input-to-output delay is critical for system timing. The MK2304S-2ITR is suitable for designs requiring both full-rate and divided-rate clocks from a single source. Ensure the PCB layout allows for 33Ω series terminating resistors on each output to minimize signal reflections as specified in the datasheet.

Part Context

This part belongs to the MK2304 family of zero-delay buffers. The 'S' denotes the SOIC package, '2' indicates the specific variant with 1X and 1/2X outputs, 'I' specifies the industrial temperature range, and 'TR' indicates tape and reel packaging. The device was originally produced by Integrated Device Technology before its acquisition by Renesas.
