The 8A34044 Four-Channel Universal Frequency Translator is a highly integrated timing device with four Digital PLL (DPLL) channels, DPLL/DCO_[0..3]; and four Digitally Controlled Oscillator (DCO) channels, DCO_[4..7]. The DPLLs can lock to external references or operate in free run, or can be configured as DCOs. Each of the DCOs can be synchronized by any of the DPLLs or another DCO, or they can operate in free run. The DCOs can alternatively be controlled by an external algorithm.

The 8A34044 supports precise control of input-to-input, input-to-output, and output-to-output phase skew. The device outputs low-jitter clocks that can directly synchronize interfaces such as 100GBASE-R, 40GBASE-R, 10GBASE-R, and 10GBASE-W and lower-rate Ethernet interfaces, as well as SONET/SDH and PDH interfaces.
