Microchip Technology

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).

The ZL40235 is a programmable or hardware pin controlled low additive jitter, low power 3 x 5 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. All the other components for building crystal oscillator are built in device such as load capacitance, series and shunt resistors. The ZL40235 has five LVPECL/HCSL/LVDS outputs which can be powered from 3.3V or 2.5V supply. Each output can be independently enabled/disabled via SPI bus. The type of each output driver can be programmed to be LVPECL, HCSL or LVDS. Hence, the device can be configured to support application where different signal formats are needed. 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.

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.

The ZL40241 is a pin controlled low additive jitter, low power 3 x 10 LVCMOS ePPS 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 ZL40241 has ten LVCMOS outputs which can be powered from 3.3V, 2.5V, 1.8V or 1.5V supply. Output can be synchronously enabled/disabled via OE pin. 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.
