Low-jitter 1:4 LVCMOS clock fanout buffer, 250 MHz, <50 ps skew, 2.5/3.3 V, TSSOP-8
The Texas Instruments CDCLVC1104 is a high-performance 1:4 LVCMOS clock fanout buffer from the CDCLVC11xx family. It distributes a single LVCMOS reference up to 250 MHz at 3.3 V (180 MHz at 2.5 V) to four outputs with less than 50 ps pin-to-pin skew and about 100 fs additive RMS jitter, and includes an asynchronous output-enable pin that parks outputs low. Typical uses include FPGA and processor clock distribution, telecom line cards, test equipment and industrial controls. Current lead time is around 26 weeks with authorized stock constrained; Cerametronics can locate traceable stock.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
What is the difference between CDCLVC1104PWR and CDCLVC1104PW?
Same device and TSSOP-8 package. PWR is the large tape-and-reel orderable (2,000 pieces on a 330 mm reel); PW is the tube orderable (150 pieces). PWRG4 and the .B-suffixed codes are the same part under different green-packaging codes and are direct substitutes.
Is there a drop-in or upgrade alternative for the CDCLVC1104?
TI recommends the LMK1C1104, a 4-channel LVCMOS buffer it describes as parametrically superior with a synchronous output enable; note it is a 1.8 V-capable device, so supply and footprint must be checked before swapping. Other CDCLVC11xx members (1:2 up to 1:12) share the pinout concept but with different pin counts.
