What are the key features of CDC340DWG4?
- 8 low-skew true outputs with 48 mA sink current drive multiple clock loads simultaneously without external buffers
- Low output-to-output skew ensures tight timing margins across distributed clock nets in multi-device systems
- 20-pin SOIC package simplifies PCB layout for clock distribution trees in processors and FPGA designs
What is CDC340DWG4 used for?
CDC340DWG4 is used for distributing a single reference clock to 8 separate loads with tightly matched propagation delays in DSP boards, FPGA evaluation kits, and multi-processor computing systems. Its 48 mA output drive enables direct connection to multiple CMOS loads without additional buffering, reducing component count in clock tree designs. The low-skew architecture maintains less than 250 ps output-to-output skew to ensure synchronous system operation across multiple clock domains.

Frequently Asked Questions
How many outputs does CDC340DWG4 drive and what is the sink current per output?
CDC340DWG4 provides 8 low-skew true outputs, each capable of sinking up to 48 mA. This high drive strength allows each output to directly drive multiple CMOS or TTL clock inputs on a PCB without needing additional buffer stages between the clock driver and the destination devices.
For an FPGA clock distribution design, how does CDC340DWG4 reduce output-to-output skew compared to cascaded logic gates?
CDC340DWG4 is specifically designed as a low-skew clock driver, maintaining tight output-to-output timing by using matched internal delay paths to all 8 outputs. Cascaded standard logic gates introduce process-dependent and load-dependent skew that can exceed 1 ns, while CDC340DWG4 keeps skew well below 250 ps, enabling synchronous clocking of multiple FPGAs or DSPs from a single source.
When should a designer choose CDC340DWG4 over a simple 74HC buffer for clock distribution?
A 74HC buffer is adequate for single-load or non-timing-critical distribution, but when 8 separate clock loads must all switch within 250 ps of each other — as required in DDR memory controllers, multi-FPGA designs, or synchronous communication boards — CDC340DWG4's matched output architecture and 48 mA drive per pin make it the correct choice. It prevents accumulated skew that 74HC fan-out chains accumulate across 3 or more gate stages.
