RTC clock synchronization buffer driver delay chip

The NB3N551 is a low skew 1:4 clock fanout buffer for clock distribution. The NB3N551 specifically guarantees low output-to-output skew. Optimized design, layout, and handling minimize skew within the device and from device to device. The output enable (OE) pin tri-states the output when low.

The NB3N2304NZ is a low-skew 1:4 clock fan-out buffer for high-speed clock distribution in applications such as PCI-X. The NB3N2304NZ guarantees low output-to-output skew. Optimized design, layout, and handling minimize skew within the device and from device to device. The output enable (OE) pin forces the output low when low.

The MC1455 monolithic timer circuit is a very stable controller capable of generating accurate time delays or oscillations. Additional terminals are available for trigger or reset if required. In time-delay mode, the timing is precisely controlled by an external resistor and capacitor. For stable operation as an oscillator, both the idle frequency and duty cycle are precisely controlled with two external resistors and a capacitor. The circuit can be toggled and reset on falling waveforms, and the output structure can source/sink up to 200 mA or drive TTL circuits.

The NB3L8504S is a differential 1:4 LVDS fanout buffer/converter with OE control for each differential output. Differential inputs driven by differential or single-ended inputs accept different logic level standards such as LVPECL, LVDS, HSTL, HCSL, and SSTL. These signals are then converted to four identical LVDS copies of the input, up to 700 MHz. Therefore, the NB3L8504S is suitable for applications requiring low-skew clock distribution.
