• 3 to 1 input Multiplexer: Two inputs accept any differential (LVPECL, HCSL, LVDS, SSTL, CML, LVCMOS) or a single ended signal and the third input accepts a crystal or a single ended signal
• Ten differential LVPECL/LVDS/HCSL outputs
• One LVCMOS output
• Ultra-low additive jitter: 24fs (integration band: 12kHz to 20MHz at 625MHz clock frequency)
• Supports clock frequencies from 0 to 1.6GHz
• Supports 2.5V or 3.3V power supplies on LVPECL,LVDS or HCSL outputs
• Supports 1.5V, 1.8V, 2.5V or 3.3V on LVCMOS outputs
• Embedded Low Drop Out (LDO) Voltage regulator provides superior Power Supply Noise Rejection
• Maximum output to output skew of 40ps
• Device controlled via control pins

The ZL40231 is a low additive jitter, low power 3 x 10 LVPECL/HCSL/LVDS 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.

The ZL40231 has ten LVPECL/HCSL/LVDS outputs which can be powered from 3.3V or 2.5V supply. Each output bank (A and B) can be independently set to be LVPECL, LVDS, HCSL or Hi-Z via control OUTA/B_TYPE_SEL0/1 pins.

The control inputs: OUTA/B_TYPE_SEL0/1 and IN_SEL0/1 have low input threshold voltage so they can be driven from a device with low I/O voltage (down to 1.2V).
