Description

The RC32312/RC32308 is an ultra-low phase noise

jitter attenuator, multi-frequency synthesizer,

synchronous Ethernet synchronizer, and digitally

controlled oscillator (DCO). This flexible, low-power

device outputs clocks with 25fs RMS jitter supporting

112Gbps and 224Gbps SerDes.

Applications

▪ Jitter attenuation for:

• 112Gbps and 224Gbps SerDes

• 100 / 200 / 400 / 800 / 1600 Gbps Ethernet PHYs

▪ Synchronous Ethernet timing cards and line cards

▪ Switches and routers

▪ Medical imaging

▪ Test and measurement

Features

▪ Jitter 25fs RMS, 12kHz to 20MHz with 4MHz HPF

▪ Output frequency range:

• 4kHz to 1GHz for differential outputs

• 4kHz to 250MHz for single-ended outputs

▪ Up to 12 HCSL (AC-LVPECL) or LVDS outputs with

independent integer dividers; differential outputs

can be configured as two single-ended outputs

▪ Up to four clock inputs that can each be configured

as differential or as two single-ended inputs

▪ Input frequency range:

• 1kHz to 1GHz for differential inputs

• 1kHz to 250MHz for single-ended inputs

▪ Compliant to ITU-T G.8262 and G.8262.1

▪ Hitless reference switching, manual or automatic

▪ DPLL input-to-output phase variation ≤ 500ps

▪ DCO frequency resolution < 10-13

▪ Factory programmable internal OTP

▪ RC32312

• 4 inputs and 12 outputs

• 9 × 9 mm, 64-VFQFPN

▪ RC32308

• 3 inputs and 8 outputs

• 7 × 7 mm, 48-VFQFPN

▪ Operating voltage: 1.8V

• Serial ports support 1.8V or 3.3V

▪ Operating temperature:

• -40°C to 85°C ambient

• -40°C to 105°C board
