IDT ClockMatrix™ 8A3404x Multi-channel DPLL / DCO Programmable, Sub-150fs Jitter Timing Solution

The ClockMatrix family of devices are high-performance, precision timing solutions designed to simplify clock designs for applications with up to 100 Gbps interface speeds. They can be used anywhere in a system to perform critical timing functions, such as clock generation, frequency translation, jitter attenuation and phase alignment. A range of devices in the family support BBU, OTN, SyncE, synthesizer and jitter attenuator applications with several density options for each.

The 8A3404x Multichannel Digital PLL / Digitally Controlled Oscillator (DPLL/DCO) family provides tools to manage timing references, clock conversion and timing paths for common communications protocols such as: Synchronous Ethernet (SyncE), Optical Transport Network (OTN) and Common Public Radio Interface (CPRI).  The device can be used to synchronize communication ports on line cards or daughter cards that are connected with synchronization sources across backplanes or other media. Digitally Controlled Oscillators (DCOs) are available to be controlled by OTN clock recovery servo software running on an external processor. Digital PLLs (DPLLs) support filtering of gapped clocks for OTN; and hitless reference switching between references from redundant timing sources. 

The device supports multiple independent timing channels for: clock generation; jitter attenuation and universal frequency translation.  Input-to-input, input-to-output and output-to-output phase skew can all be precisely managed.  The device outputs ultra-low-jitter clocks that can directly synchronize SERDES running at up to 28Gbps; as well as CPRI/OBSAI, SONET/SDH and PDH interfaces
