PI6C185-01LE

Clock Buffers, Drivers Overview

The PI6C185-01LE is a precision 1-to-5 non-inverting clock buffer manufactured by Diodes Incorporated. Designed for SDRAM clock distribution in Intel Architecture-based mobile systems, it supports switching speeds up to 140 MHz with low skew of less than 250 ps between any two output clocks. The device operates on a single 3.3V supply and features an I2C serial configuration interface for individually enabling or disabling each of the five outputs. It is housed in a 16-pin TSSOP package.

Clock Buffers, Drivers Feature Summary

• High-speed 1:5 non-inverting buffer supporting frequencies up to 140 MHz
• I2C serial control allows individual activation/deactivation of five SDRAM outputs
• Low output skew (<250 ps) ensures precise clock synchronization
• Multiple VDD and VSS pins provided for noise reduction

Clock Buffers, Drivers Applications

• SDRAM clock buffering for mobile systems
• Clock distribution for systems supporting up to two SODIMMs
• Intel Architecture-based mobile platform designs

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'LE' corresponds to the Pb-free and Green compliant version in the 16-pin TSSOP package. Confirm that the commercial temperature range (-40°C to +85°C) meets system requirements. Ensure I2C address lines are configured correctly, as the device functions as a slave receiver without read-back capability.

Clock Buffers, Drivers Selection Notes

Select this component when a low-skew 1:5 buffer is required for SDRAM applications. The I2C interface is necessary if dynamic enable/disable control of individual clock outputs is needed. Verify that the input signal levels are compatible with the specified TTL clocking interface and that the load capacitance does not exceed the maximum specified limits.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C185 series of precision clock buffers. It is specifically intended for use with PI6C10X clock generators in mobile architectures. The 'L' suffix denotes the 16-pin TSSOP package, while 'E' indicates environmental compliance (Pb-free/Green).

Clock Buffers, Drivers Replacement Considerations

The standard PI6C185-01L is the non-environmental variant of the same functional device. Other Pi6C series buffers may offer different fan-out ratios or interfaces but lack the specific I2C-controlled SDRAM optimization of this model.
