CDCL1810A 1.8V, 10 Output, High-Performance Clock Distributor
Single 1.8 V Supply
distributor. The programmable dividers, P0 and P1,
High-Performance Clock Distributor with 10
give a high flexibility to the ratio of the output
frequency to the input frequency: FOUT = FIN/P, where
Low Input-to-Output Additive Jitter: as low as 10fs
P (P0,P1) = 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80.
The CDCL1810A supports one differential LVDS
Low-Voltage Differential Signaling (LVDS) Input,
clock input and a total of 10 differential CML outputs.
Ω Differential On-Chip Termination, up to 650
The CML outputs are compatible with LVDS receivers
if they are ac-coupled.
Differential Current Mode Logic (CML) Outputs,
With careful observation of the input voltage swing
Ω Single-Ended On-Chip Termination, up to
and common-mode voltage limits, the CDCL1810A
650 MHz Frequency
can support a single-ended clock input as outlined in
Pin Configuration and Functions.
Two Groups of Five Outputs Each with
Independent Frequency Division Ratios
All device settings are programmable through the
Output Frequency Derived with Divide Ratios of 1,
interface is 1.8V tolerant only.
2, 4, 5, 8, 10, 16, 20, 32, 40, and 80
