• * Ten 1.5V/1.8V/2.5V/3.3V LVCMOS outputs

• * Supports frequencies from 0 to 250MHz

• * Ultra-low system level additive jitter: 17fs (12kHz to 20MHz)

• * Ultra-low noise floor of -170dBc/Hz

• * Supports crystals from 8MHz to 160MHz

• * Supports 2.5V or 3.3V power supplies

• * Output to output skew of 30ps (typical)

• * Input to output delay of 2ns (typical)

• * SPI or Hardware control

Description

The ZL40240 is a programmable or hardware pin controlled low additive jitter, low power 3 x 10 LVCMOS fanout buffer. Two inputs can accept signal in differential (LVPECL, SSTL, LVDS, HSTL, CML ) or single ended (LVPECL or LVCMOS) format and the third input can accept a single ended signal or it can be used to build a crystal oscillator by connecting an external crystal resonator between its XIN and XOUT pins. All the other components for building crystal oscillator are built in device such as load capacitance, series and shunt resistors. The ZL40240 has ten LVCMOS outputs which can be powered from 3.3V, 2.5V, 1.8V or 1.5V supply. Each output can be independently enabled/disabled via SPI bus. In addition, the strength of each output can be programmed. The device operates from 2.5V+/-5% or 3.3V+/-5% supply. Its operation is guaranteed over the industrial temperature range -40°C to +85°C.
