ZL30253LDF1 General Description

CREATE AND SAMPLE YOUR CUSTOM ZL30253 HERE

The ZL30253 is a flexible, high-performance, clock multiplier/jitter attenuator IC. From any input clock frequency 1kHz to 1250MHz the ZL30252 can produce frequency-locked output frequencies from 1Hz to 1035MHz and as many as 3 differential or 6 CMOS output clock signals. Output jitter is typically 0.16 to 0.28ps RMS (12kHz to 20MHz). Automatic self-configuration from internal EEPROM allows clock signals to be available immediately after power-up or reset.

Key Features

Two Differential/CMOS inputs
One single-ended/CMOS input
Any input frequency from 1kHz to 1250MHz (1kHz to 300MHz for CMOS)
Inputs continually monitored for activity and frequency accuracy
Automatic or manual reference switching

Programmable bandwidth, 14Hz to 500Hz
Attenuates jitter up to several UI
Freerun or digital hold on loss of all inputs
Digitally controlled phase adjust

Any Output Frequency from <1Hz to 1035MHz
High-resolution fractional frequency conversion with 0ppm error
Easy-to-configure, encapsulated design requires no external VCXO or loop filter components
Each output has independent dividers
Output Jitter Typically 0.16 to 0.28ps RMS (12kHz to 20MHz integration band)
Outputs are CML or 2xCMOS, can interface to LVDS, LVPECL, HSTL, SSTL and HCSL
In 2xCMOS mode, the P and N pins can be different frequencies (e.g. 125MHz and 25MHz)
Per-output supply pin with CMOS output voltages from 1.5V to 3.3V
Precise output alignment circuitry and per-output phase adjustment
Per-output enable/disable and glitchless start/stop (stop high or low)

Automatic self-configuration at power-up from internal EEPROM; up to four configurations, pin-selectable
Numerically controlled oscillator mode
Spread-spectrum modulation mode
SPI or I2C processor Interface
Tiny 5x5mm QFN package
Easy-to-use evaluation software
ZL30253 can be ordered with up to four user-defined, factory-programmed device configurations
