The CDCL1810 is a high-performance clock distributor. The programmable dividers, P0 and P1, give a high flexibility to the ratio of the output frequency to the input frequency: FOUT = FIN/P, where: P (P0,P1) = 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80.
The CDCL1810 supports one differential LVDS clock input and a total of 10 differential CML outputs. The CML outputs are compatible with LVDS receivers if they are ac-coupled.
With careful observation of the input voltage swing and common-mode voltage limits, the CDCL1810 can support a single-ended clock input as outlined in Pin Configuration and Functions.
All device settings are programmable through the SDA/SCL, serial two-wire interface. The serial interface is 1.8V tolerant only.
The phase of one output group relative to the other can be adjusted through the SDA/SCL interface. For post-divide ratios (P0, P1) that are multiples of 5, the total number of phase adjustment steps (η) equals the divide-ratio divided by 5. For post-divide ratios (P0, P1) that are not multiples of 5, the total number of steps (η) is the same as the post-divide ratio. The phase adjustment step (ΔΦ) in time units is given as: ΔΦ = 1/(n × FOUT), where FOUT is the respective output frequency.
The device operates in a 1.8-V supply environment and is characterized for operation from –40°C to +85°C. The CDCL1810 is available in a 48-pin VQFN (RGZ) package.
