Product Data Sheet

GENERAL DESCRIPTION

The M1033/34 is a VCSO (Voltage Controlled SAW

Oscillator) based clock jitter

attenuator PLL designed for clock

jitter attenuation and frequency

translation. The device is ideal for

generating the transmit reference

clock for optical network systems

supporting up to 2.5Gb data rates.

It can serve to jitter attenuate a

stratum reference clock or a recovered clock in loop

timing mode. The M1033/34 module includes a

proprietary SAW (surface acoustic wave) delay line as

part of the VCSO. This results in a high frequency,

high-Q, low phase noise oscillator that assures low

intrinsic output jitter.

FEATURES

◆ Integrated SAW delay line; low phase jitter of < 0.5ps

rms, typical (12kHz to 20MHz)

◆ Output frequencies of 62.5 to 175 MHz

(Specify VCSO output frequency at time of order)

◆ LVPECL clock output (CML and LVDS options available)

◆ Reference clock inputs support differential LVDS,

LVPECL, as well as single-ended LVCMOS, LVTTL

◆ Loss of Reference (LOR) output pin; Narrow Bandwidth

control input (NBW pin)

◆ AutoSwitch (AUTO pin) - automatic (non-revertive)

reference clock reselection upon clock failure

◆ Acknowledge pin (REF_ACK pin) indicates the actively

selected reference input

◆ Phase Build-out only upon MUX reselection option

(PBOM)

◆ Pin-selectable feedback and reference divider ratios

◆ Single 3.3V power supply

◆ Small 9 x 9 mm SMT (surface mount) package
