Product Specifications

Included Model List

A CDR (clock and data recovery) IC extracts the clock from an incoming NRZ data stream and retimes the data with it, which removes jitter accumulated along the fibre and gives the next stage a clean eye. Several devices below also include the limiting amplifier, so one chip covers both quantization and retiming. All models are grouped into this single product, so you can send us the models and quantities you need in one enquiry.

Product Details

Applications

Receiver side of SFP, SFP+ and XFP optical modules, SONET/SDH OC-3, OC-12, OC-48 and OC-48 with FEC regenerators and terminal receivers, Gigabit Ethernet and 1.25 Gbps and 2.5 Gbps links, GPON, BPON and EPON OLT and ONU ports, DWDM transponders that need protocol agnostic recovery, and line cards where the data rate is not known in advance.

Features

Continuous rate locking from 10 Mbps or 12.3 Mbps up to 2.7 Gbps without an external reference clock or programming, multirate operation on fixed rate parts such as MAX3872, integrated limiting amplifier and slice level adjust, programmable loss of signal (LOS) detection, loss of lock (LOL) status, BER monitor and PRBS generator and detector on the ADN2817, I2C access to optional features, and single 3.3 V supply with typical power from 350 mW.

Companion Chips

A complete receiver chain uses a PD or ROSA with a TIA (ADN2880, ADN2882, ADN2820, MAX3266, MAX3267), then a CDR such as these, controlled by an optical module controller (ADuC7020, ADuC7021, DS4830, DS4834) with a TEC controller (ADN8830, ADN8831, MAX8520, MAX8521) for cooled optics. On the transmit side we also supply the matching laser driver families (ADN2525, ADN2530, ADN2872, MAX3668, MAX3945).

Frequently Asked Questions

Q: What models are included in this product?
A: ADN2804, ADN2805, ADN2806, ADN2812, ADN2813, ADN2814, ADN2817, ADN2818, MAX3872, MAX3875, MAX3875A, MAX3876, MAX3877, MAX3878, and more. Please contact us for the full list.
Q: What is the difference between the continuous rate and fixed rate parts?
A: Continuous rate devices such as ADN2812, ADN2814 and ADN2817 lock to any rate in their range without a reference clock, which suits multi protocol line cards. Fixed rate devices such as ADN2804 and ADN2806 are optimised for a single rate, for example 622 Mbps in PON applications, with lower power.
Q: Which CDR parts include the limiting amplifier?
A: ADN2804, ADN2812, ADN2813, ADN2814, ADN2817 and MAX3872 include the limiting amplifier. ADN2806 and ADN2818 are the versions without it, for designs that already have a separate limiting amp.
Q: Can you supply obsolete and hard-to-find types?
A: Yes. MAX3875, MAX3876, MAX3877 and MAX3878 are mature SONET and SDH types, and we hold or source them from verified stock. Send the model, quantity and target price and we will reply with availability.
