الوصف

نظرة عامة على المنتج

The CDCLVC1104PWR is a low-jitter 1:4 LVCMOS fan-out clock buffer from Texas Instruments, packaged in an 8-pin TSSOP (PW) package. It provides four LVCMOS output copies of a single LVCMOS input with an additive jitter of only 70 fs typical and output skew of less than 50 ps. The device operates from 2.5V or 3.3V supplies and supports frequencies up to 250 MHz at 3.3V.

مقدمة المنتج:CDCLVC1104PWR مقدمة المنتج

The CDCLVC1104 is a low-jitter, high-fan-out LVCMOS clock buffer that produces four identical copies of a single LVCMOS input clock. With additive jitter of only 70 fs typical and output skew below 50 ps, it preserves the timing integrity of precision clock sources throughout the distribution network. The device is part of a pin-compatible family ranging from 1:2 to 1:12 fan-out configurations, allowing designers to scale clock distribution without board layout changes. The LMK1C1104 is a newer pin-compatible version that also supports 1.8V supply operation with even lower jitter performance.

مبدأ العمل:CDCLVC1104PWR مبدأ العمل

The CDCLVC1104 receives a single-ended LVCMOS clock input and distributes it to four identical LVCMOS output drivers through a carefully matched internal clock tree. The input buffer converts the LVCMOS signal to an internal logic level, which is then routed through symmetric metal traces to four output drivers. The matched trace lengths and balanced driver impedances ensure that all four outputs switch simultaneously within 50 ps of each other (output skew). The output enable (1G) pin provides asynchronous control to tri-state all outputs when de-asserted, allowing clock gating for power management. The low additive jitter is achieved through low-noise internal bias circuits and fast edge rates on the output drivers.
