CLOCKMATRIX OVERVIEW
TMThe Renesas ClockMatrix family of multi-channel timing devices reduces the complexity and costof clock trees by replacing multiple timing chips with a single timing resource. The devices support
a wide range of frequencies and signal types at their inputs and outputs.

ClockMatrix devices include two types of timing channels: Digital PLL / Digitally Controlled Oscillator(DPLL/DCO) channels and DCO only channels. Any DCO can free run based on the local oscillator.
They can be controlled by external software or they can be connected to a DPLL channel to supply
additional outputs and frequencies for that DPLL.
A wide range of simple to complex timing and synchronization applications are covered by theClockMatrix family using its flexible architecture, a common register set and a few package types.

Range of Applications

In the ClockMatrix family, the Universal Frequency Translator (UFT) devices perform jitter
attenuation and frequency translation functions for general purpose applications.

■ Baseband and Radio Units

TMSystem synchronizers generate ITU-T compliant clocks for telecom systems while the telecom line
card synchronizers generate ITU-T complaint clocks for line cards locked to a system synchronizer.

CLOCKMATRIX FAMILY OVERVIEW
ClockMatrix 2 devices deliver improved performance with phase jitter as low as 88 fs-rms. The highly integrated devices provide all the functionality
needed to implement an IEEE 1588 clock solution with jitter attenuation capabilities resulting in ultra-low jitter clock outputs for Synchronous Ethernet
PHYs with data rates up to 112Gbps, reducing design complexity and bill of materials (BOM) requirements, while also allowing customers to apply thetiming devices to a wide variety of network applications.
