Quad Sine-Wave Clock Buffer: CDC3S04 The Texas Instruments CDC3S04 quad sine-wave clock buffer with LDO can be used to buffer a single master clock to multiple peripherals. The TI CDC3S04 has four sine-wave outputs designed for minimal channel-to-channel skew and ultralow additive output jitter. This TI sine-wave clock buffer features ultralow phase noise, ultralow standby current, and individual clock request inputs for each output. The CDC3S04 clock buffer is optimized for use in cellular phones, smart phones, mobile handsets, and more.
