The CDCL1810A 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 CDCL1810A 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 CDCL1810A 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 device operates in a 1.8V supply environment and is characterized for operation from –40°C to +85°C. The CDCL1810A is available in a 48-pin QFN (RGZ) package.
