M1020/21

VCSO BASED CLOCK PLL

GENERAL DESCRIPTION

PIN ASSIGNMENT (9 x 9 mm SMT)

The M1020/21 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 M1020/21 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)
