MS86040 Overview
A PAM4 CDR is a clock-and-data-recovery integrated circuit used in high-speed serial communication. It recovers a usable data stream and timing reference from a corrupted or noisy received signal, supporting the transmitter, optical or copper interconnect, and downstream digital processing. The MS86040 belongs to the broader receiver and signal-integrity hierarchy: PAM4 CDR, clock-and-data-recovery IC, high-speed communication IC, and semiconductor.
The main verified capabilities are four independent channels, operation at 26.5625GBaud or 53.125Gb/s, low power consumption, and low-latency analog recovery. Output swing can be programmed as high as 900mVppd. De-emphasis can be programmed to compensate for connector and PCB losses, while global hardware pads report loss-of-lock and loss-of-signal conditions. These functions help simplify system bring-up, link monitoring, and board-level equalization.
The MS86040 is associated with 200G SR4 and 400G SR8 chipset applications, where parallel optical lanes commonly use PAM4 signaling. Its four-channel architecture can support multi-lane receiver implementations, while the analog CDR organization is intended to reduce processing latency. The verified material also describes compatibility with 250 micrometer pitch PIN diode arrays, useful for optical front-end integration.
System designers should evaluate the device against the exact electrical, package, pinout, power, and timing requirements of the target optical module. The manufacturer page confirms the core signaling and control functions, but the supplied data does not include a package identifier, pin count, supply voltage, power-consumption figure, or complete datasheet parameter table. Those details must be obtained from the official MS86040 datasheet before layout or production sourcing is finalized.
This product summary consolidates the verified MiniSilicon product-page information and clearly separates unavailable specifications from published facts. It supports early architecture evaluation for PAM4 optical links, SR4/SR8 receiver designs, and high-speed communication modules without inventing electrical values that were not present in the retrieved source data.

Typical Applications
MS86040 is suitable for 6 applications: 200G SR4 Optical Receiver, 400G SR8 Optical Receiver, PAM4 Optical Front-End, High-Speed Parallel Link Interface, Optical Module Clock-and-Data Recovery, Connector and PCB Equalization.
200G SR4 Optical Receiver
The MS86040 fits a 200G SR4 receive path because it provides four independent channels at 26.5625GBaud, corresponding to 53.125Gb/s per lane. Its low-latency analog CDR organization is suitable for recovering clock and data from parallel optical lanes, while the programmable output swing and de-emphasis provide board-level control for downstream circuitry. The verified application listing specifically associates the device family with 200G SR4 designs. Before layout release, confirm detector compatibility, input sensitivity, power rails, package dimensions, and channel-to-channel timing requirements in the official datasheet.
Recommended
400G SR8 Optical Receiver
MS86040 is relevant to multi-lane 400G SR8 receiver architectures because its four-channel structure and 53.125Gb/s-per-lane capability address high-speed PAM4 signaling. The receiver can interface with a 250 micrometer pitch PIN diode array according to the verified product information, while programmable de-emphasis helps compensate for connector and PCB loss. A complete SR8 implementation still requires validated optical front-end, packaging, thermal, and signal-integrity designs that are not included in the retrieved source data.
Recommended
PAM4 Optical Front-End
The MS86040 can be used in a PAM4 optical front-end where recovered high-speed data must be transferred between a photodetector array and downstream digital or retiming circuitry. Its compatibility with 250 micrometer pitch PIN diode arrays is directly relevant to this signal chain, and its independent receiver channels allow parallel-lane implementation. The verified data does not specify input bandwidth, sensitivity, common-mode range, or package parasitics, so those parameters must be obtained from the manufacturer datasheet before component selection.
Recommended
High-Speed Parallel Link Interface
MS86040 is suitable for early evaluation in high-speed parallel link interfaces requiring independent clock-and-data recovery on four lanes. The 53.125Gb/s-per-lane rate and low-latency analog CDR can reduce protocol-processing distance between the physical receiver and downstream logic. Output swing programming and de-emphasis give system engineers two implementation controls, but actual eye closure, jitter, insertion-loss tolerance, and interoperability must be characterized with the target transmitter, connector, PCB, and protocol PHY.
Recommended
Optical Module Clock-and-Data Recovery
In an optical module, the MS86040 can serve as a receiver-side CDR for recovering timing and data from multiple high-speed electrical lanes. The four independent channels support a quad-lane architecture, and the global LOL and LOS pads provide hardware status visibility for module supervision. Its I2C interface allows an external controller to manage configuration, while programmable output swing and de-emphasis support board-level tuning. Exact I2C register behavior, status polarity, and control timing require the official MS86040 datasheet.
Recommended
Connector and PCB Equalization
The MS86040's programmable output de-emphasis is useful when a recovered signal must traverse a connector or lossy PCB path before reaching the next receiver. By compensating channel loss in a controlled way, the feature can help preserve signal integrity in a multi-lane architecture. The verified source states the function but does not provide de-emphasis range, step size, bandwidth, or recommended settings. Engineers should characterize the complete channel with measurements rather than applying an assumed preset.

Design Notes
Design the MS86040 receiver path around the verified 53.125Gb/s-per-lane capability and the physical channel between the PIN diode array and CDR inputs. Keep high-speed traces short and controlled, provide a continuous reference plane, and account for differential impedance, connector launch, package transitions, and loss through de-insertion and equalization. Because the supplied data does not specify input sensitivity, jitter tolerance, or channel bandwidth, validate those parameters with the actual optical front end and connector.
Use the official MiniSilicon package drawing before assigning PCB land patterns or vias. The retrieved material does not provide the package, pin count, pin names, or exposed-pad requirements, so a footprint cannot be responsibly recommended here. Confirm power and ground connectivity, high-speed differential routing, reference-plane continuity, and thermal-via requirements directly against the manufacturer datasheet and reference layout.
Programmable output swing and output de-emphasis are useful tuning controls, but they should be evaluated as part of the complete link rather than selected independently. Start with the manufacturer's recommended settings, then characterize eye opening, jitter, crosstalk, and downstream receiver tolerance while varying output swing and de-emphasis. Do not infer the control range from the confirmed maximum of 900mVppd because the minimum, step size, and legal operating modes are not supplied.
Do not treat MS86040 as a generic four-channel data converter or assume that its receiver channels can replace the transmit function of the related MS87040. The verified material identifies MS86040 as the receive-side PAM4 CDR and MS87040 as the transmit-side device with an integrated VCSEL-driver array. Confirm directionality, protocol timing, lane mapping, status-pin polarity, and I2C register behavior in the official documentation before schematic sign-off.
Compliance Information
The supplied verified product information does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Compliance must be confirmed with MiniSilicon using the exact MS86040 orderable part and current material documentation.
