ZL30621

3-Output Any Frequency Timing Card

PLL with Ultra-Low Jitter

Data Sheet

January 2018

Features

Ordering Information

• Low-Bandwidth DPLL

ZL30621LFG7

ZL30621LFF7

64 Pin LGA

Trays

Tape and Reel

• ITU-T G.813/G.8262 compliance (options 1 & 2)

Ni Au

• Low-jitter operation from any 10MHz TCXO

Package size: 5 x 10 mm

• Master clock jitter attenuator reduces cost by



-40 C to +85 C

removing TCXO/OCXO low-jitter requirement

• Programmable bandwidth, 0.1Hz to 10Hz

• Attenuates input clock jitter up to several UI

• Hitless reference switching

• 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)

• High-resolution holdover averaging

• Digitally controlled phase adjustment

• Input Clocks

• Per-output supply pin with CMOS output

voltages from 1.5V to 3.3V

• Precise output alignment circuitry and per-

output phase adjustment

• Up to 3 inputs, 2 differential/CMOS, one CMOS

• Per-output enable/disable and glitchless

• Any input frequency from 8kHz to 1250MHz

start/stop (stop high or low)

(8kHz to 300MHz for CMOS)

• General Features

• Per-input activity and frequency monitoring

• Automatic or manual reference switching

• Automatic self-configuration at power-up from

internal EEPROM; up to four configurations

pin-selectable

• Low-Jitter Fractional-N APLL and 3 Outputs

• Any output frequency from <1Hz to 1035MHz

• Numerically controlled oscillator mode

• Input-to-output alignment with external feedback

• SPI or I²C processor Interface

• High-resolution fractional frequency conversion

with 0ppm error

• Encapsulated design requires no external

• Easy-to-use evaluation software

VCXO or loop filter components

• Each output has independent dividers

Applications

•

Telecom timing cards for SONET/SDH, SyncE,

wireless base stations and other systems

• Output jitter as low as 0.25ps RMS (12kHz-

20MHz integration band)
