Texas Instruments CDCLVP110 Low-Voltage 1 to 10LVPECL HSTL with Selectable Input Clock Driver

Summary

This sophisticated differential clock driver is engineered for high-speed, low-skew clock distribution in critical digital systems. It accepts single or dual LVPECL/HSTL inputs and distributes the signal across ten pairs of complementary outputs, supporting operations up to 3.5 GHz while maintaining compatibility with $50\Omega$ transmission lines. The accompanying technical manual provides comprehensive details on electrical characteristics, pin configurations, supply voltage options, and optimal application guidelines for system designers tackling complex timing requirements.

Frequently Asked Questions

What voltage supply is required for the CDCLVP110?

The device requires a single supply voltage of ±3.3-V or can accept two clock sources into an ±2.5-V Supply input multiplexer.

How do I select between CLK0 and CLK1 input pairs?

Use the CLK_SEL pin: setting it to 0 selects CLK0, and setting it to 1 selects CLK1.

What low-skew copies of the clock are provided?

The outputs Q[9:0] (pins 20, 22, 24, 27) provide LVECL/LVPECL clock outputs with low skew, and pins 29, 31 provide complementary copies.

Is an external reference voltage needed for single-ended operation?

Yes, the VBB pin should be connected to CLK0 and bypassed to GND via a 10-nF capacitor.
