M1025/26

VCSO BASED CLOCK PLL WITH AUTOSWITCH

GENERAL DESCRIPTION

The M1025/26 is a VCSO (Voltage Controlled SAW

Oscillator) based clock jitter

PIN ASSIGNMENT (9 x 9 mm SMT)

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 M1025/26 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.
