ZL40203LDG1

The ZL40203LDG1 from Microchip Technology is a high-performance clock buffer designed for general-purpose clock distribution and low-jitter clock trees. It accepts differential or single-ended inputs, supporting logic levels such as LVPECL, LVDS, CML, HCSL, and LVCMOS. The device features on-chip input termination resistors and biasing for AC-coupled inputs.

This fanout buffer provides four precision LVPECL outputs and can operate at frequencies up to 750 MHz. It is designed for a supply voltage range of 2.375V to 3.465V and has a core current consumption of 62 mA. An on-chip Low Drop Out (LDO) regulator is included for superior power supply rejection. The ultra-low additive jitter of 40 fs RMS makes it suitable for demanding applications.

Packaged in a compact 16-VFQFN (3x3 mm) with surface mount termination, the ZL40203LDG1 is suitable for applications requiring precise clock signal distribution. Its operating temperature range is -40°C to 85°C.

Applications for the ZL40203LDG1 include logic translation, clock and data signal restoration, wired communications (OTN, SONET/SDH, GE, 10 GE, FC, 10G FC), PCI Express clock distribution, wireless communications, and high-performance microprocessor clock distribution.
