MC100ES6039DW

Clock Generators, PLLs, Frequency Synthesizers Overview

The MC100ES6039DW is a low skew clock generation chip from the 100E series, manufactured by Freescale Semiconductor. It provides ÷2/4 and ÷4/6 division ratios with four true differential outputs in a 20-lead SOIC package. The device supports ECL, PECL, HSTL, and LVDS input signals, operating within a frequency range exceeding 1.0 GHz. Key electrical parameters include a maximum output-to-output skew of 50 ps and propagation delays ranging from 500 to 875 ps depending on the signal path. Power supply requirements are VCC = 0 V with VEE = -3.135 V to -3.8 V for ECL mode, or VCC = 3.135 V to 3.8 V with VEE = 0 V for PECL mode.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify that the ordering suffix 'DW' corresponds to the 20-lead SOIC package (Case 751D-07). Confirm RoHS compliance status if required, as standard versions may not be lead-free compared to the 'EG' suffix variants. Ensure power supply connections for all VCC and VEE pins are externally connected to guarantee proper operation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when sub-nanosecond skew is critical between multiple divided clock outputs. The internal dividers are synchronous, ensuring common output edges are precisely aligned. Consider the ÷2/4 and ÷4/6 configuration options via DIVSELa and DIVSELb inputs. Verify compatibility with the system's input signal type, as the device accepts differential or single-ended ECL, PECL, HSTL, or LVDS signals.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MC100ES6039 belongs to the 100ES Series, which features temperature compensation. It is designed explicitly for applications demanding low skew clock generation. The device integrates internal pull-up and pull-down resistors (75 kΩ) on input pins to define default states when left open.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How does the device handle startup states?

Upon startup, internal flip-flops attain a random state. For systems using multiple ES6039s, the Master Reset (MR) input must be asserted to ensure synchronization. Single-device systems do not require MR exercise due to internal divider design ensuring synchronization between ÷2/4 and ÷4/6 outputs.

What is the function of the EN pin?

The Enable (EN) pin is synchronous, meaning internal dividers are only enabled or disabled when the internal clock is already in the LOW state. This prevents the generation of runt clock pulses during enable/disable transitions.

Can the device accept single-ended inputs?

Yes, the device can be driven by either differential or single-ended ECL, PECL, HSTL, or LVDS input signals. If a single-ended input is used, the VBB output should be connected to the CLK input and bypassed to ground via a 0.01 µF capacitor.
