Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Introduction

‌BCM85821A0KEFBG is an 800G (8:4) PAM-4 DSP PHY device that does not include an integrated laser driver ‌‌. Designed for high-bandwidth applications, the device delivers best-in-class module performance in terms of bit error rate and power consumption, meets all IEEE and OIF standards, and supports MR Links on the chip-to-module electrical interface ‌.

Features

Single-chip 4 x 200G PAM-4 PHY Drives 800GbE via fiber:

Client :8 x 106G PAM-4

Line end :4 × 226G PAM-4 (128,120 internal code, with 2-bit fill)

Support forward gear box, backward compatible 400G optical module:

Client :8 x 53G PAM-4

Line side: 4 x 106G PAM-4

Supports client crossbar system and can be flexibly routed to various standards

Supports 100G repeater mode

Supports FEC monitoring in repeater mode with secondary sampling feature to reduce power consumption

Supports FEC termination and generation

Support differential line end output

Both the line end (10 taps) and the client end (7 taps) support TX FIR

The client interface complies with:

The IEEE 802.3ck C2C (Appendix 135F) specification supports medium-range channels

The IEEE 802.3ck C2M (Appendix 135G) specification supports the chip-to-module channel

The CEI-112G-VSR/MR Specification supports both short range (VSR) and medium range (MR) channels

IEEE 802.3cd compliant KP4 and end-to-end FEC bypass operation: - 800G/400G/200G/100G KP4 FEC

The client provides link training support

Loop between the line end and the client

Lowest power 5-nm CMOS design

Integrated AVS regulator

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
