Device Overview

Summary

The ZL40234 is a pin configurable low additive jitter, low power 3 x 4 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 ZL40234 has four LVPECL/HCSL/LVDS outputs in two banks and each bank can independently be powered from 3.3V or 2.5V supply. Differential outputs can be set to be LVPECL, LVDS, HCSL or Hi-Z via control OUT_TYPE_SEL0/1 pins.

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.


Additional Features
  • 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
  • Four differential LVPECL/LVDS/HCSL outputs
  • One LVCMOS output
  • Ultra-low additive jitter: 24fs (in 12kHz to 20MHz integration band at 625MHz clock frequency)
  • Supports clock frequencies from 0 to 1.6GHz
  • Supports 2.5V or 3.3V power supplies for LVPECL,LVDS or HCSL outputs
  • Supports 1.5V, 1.8V, 2.5V or 3.3V for LVCMOS output
  • 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
