MATA-37144 Overview
A clock and data recovery amplifier, or CDR, reconstructs a usable digital data stream and recovered clock from a degraded high-speed optical signal. This MACOM device combines the photodiode-input TIA, decision circuitry, and output-driver functions in one optical receiver path. In the signal-chain hierarchy, it belongs to clock and timing components and interface electronics, rather than a general-purpose digital logic IC.
The MATA-37144 is specifically identified as a four-channel 25G/28G CDR with an integrated TIA. Its high-sensitivity TIA includes selectable bandwidth for legacy-rate support. After amplification, the limiting amplifier provides a defined decision function, while programmable output swing and de-emphasis allow downstream circuitry to be matched to channel and board conditions. Programmable slice-level adjustment and LOS-threshold control support receiver calibration and loss-of-signal detection.
The verified source also associates the MATA-37144 with an average photodiode-current monitor identified as RSSI. This measurement feature helps a system evaluate received optical power indirectly. Together, the TIA, slicer, LOS control, RSSI monitoring, and programmable driver create a configurable receiver chain rather than a fixed-gain amplifier. Exact gain, sensitivity, bandwidth selections, data rates, supply voltage, power consumption, and channel-to-channel coupling require datasheet verification.
The most relevant applications are 25G/28G optical transceiver receivers, legacy-rate-compatible optical links, parallel four-channel architectures, receiver equalization and de-emphasis experiments, and loss-of-signal monitoring systems. For these uses, designers should evaluate channel budget, photodiode capacitance, target line rate, recovery range, output impedance, and PCB channel loss before committing to a receiver implementation.
A key design consideration is that programmable bandwidth, slice level, LOS threshold, output swing, and de-emphasis do not replace optical-power budgeting or channel simulation. Set receiver controls through validated firmware, preserve receiver eye margin, and verify compliance with the exact variant datasheet. The available evidence does not identify whether MATA-37144 is a catalog, die, tape-and-reel, or other package configuration.
This page separates verified manufacturer-level facts from unavailable parameters and records every missing electrical or package attribute rather than estimating it. It also explains why a same-footprint replacement cannot be recommended until the package and pinout are verified. For an equivalent device, compare data rate, channel count, optical input sensitivity, bandwidth modes, LOS behavior, RSSI implementation, electrical interfaces, supply requirements, and package-level pin compatibility.

Typical Applications
MATA-37144 is suitable for 6 applications: 25G/28G Optical Transceiver Receivers, Parallel Four-Channel Optical Links, Legacy-Rate-Compatible Optical Receive Paths, Loss-of-Signal Detection and RSSI Monitoring, High-Speed Photodiode Amplification, Programmable Output Equalization.
25G/28G Optical Transceiver Receivers
The MATA-37144 fits parallel 25G/28G receiver channels because the verified data identifies four integrated high-sensitivity TIAs and four clock-and-data-recovery paths. Place each photodiode channel into a complete receiver chain that can use selectable TIA bandwidth, a limiting-amplifier stage, and programmable output swing. The programmable de-emphasis setting is useful when PCB or cable loss would otherwise degrade the transmitted edge. Before schematic release, verify optical sensitivity, channel isolation, electrical output interface, power consumption, and package availability; none of those values is supplied here.
Recommended
Parallel Four-Channel Optical Links
MATA-37144 is appropriate when an optical interface requires four independently recovered data paths rather than a single-channel amplifier. The four-channel architecture can reduce the number of separate receiver assemblies while retaining per-channel TIA, limiting, output-driver, slice-level, and LOS-threshold functions. System planners should confirm whether all four channels must operate concurrently at the same rate and what channel-to-channel performance is guaranteed. Exact simultaneous-rate limits, crosstalk, skew, and package routing data require the missing manufacturer documentation.
Recommended
Legacy-Rate-Compatible Optical Receive Paths
The selectable-bandwidth TIA in MATA-37144 allows receiver configurations to target legacy data rates as well as its identified 25G/28G capability. This is useful when the same optical transport equipment must interoperate with multiple line rates. The receiver should be tuned across a verified list of operating modes rather than assuming every intermediate rate is supported. Engineers need the missing bandwidth settings, sensitivity-versus-bandwidth curves, lock range, and oversampling requirements to establish a reliable mode table and receiver-eye margin.
Recommended
Loss-of-Signal Detection and RSSI Monitoring
MATA-37144 supports receiver supervision through a programmable LOS threshold and an average photodiode-current monitor identified as RSSI. These functions can help firmware distinguish loss-of-signal from a valid received waveform and estimate average optical input power. Calibration should map the monitor reading against known optical power at the actual receiver plane, accounting for optical coupling and package tolerances. Threshold timing must also prevent false assertions during startup or acquisition; hysteresis behavior and monitor accuracy are not included in the verified source.
Recommended
High-Speed Photodiode Amplification
The integrated high-sensitivity TIA makes MATA-37144 applicable to receivers that convert weak photodiode currents into recoverable digital signals. Selectable bandwidth can balance receiver sensitivity against the bandwidth needed for the intended line rate, while the subsequent limiting amplifier establishes a decision-oriented waveform. Layout must minimize parasitic capacitance and sensitive trace length around the optical input. Obtain input-current, input-capacitance, transimpedance, bandwidth, recovery-time, and overload specifications before setting the photodiode and receiver operating point.
Recommended
Programmable Output Equalization
MATA-37144 provides programmable output swing and de-emphasis, allowing receiver output characteristics to be adjusted for downstream channel loss and device loading. This control can help engineers tune edge amplitude after TIA and limiting stages without treating every channel as a fixed-output amplifier. Validation should sweep de-emphasis and swing against the worst-case PCB or cable channel, then measure eye opening, jitter, power consumption, and downstream compliance. The permitted programming range, step size, control interface, and stability boundaries remain data-needed items.

Design Notes
Treat the photodiode input as a high-speed analog node and obtain the official pinout, input capacitance limits, TIA bandwidth settings, and recommended layout before routing. Keep the optical-input path short, minimize via and stub effects, and use a continuous reference plane where the package allows. Estimated: any PCB loss budget should be derived from simulated channel insertion loss plus photodiode and package parasitics; those values cannot be calculated from the supplied data.
Do not classify MATA-37144C-DIE, MATA-37144C-SIX, or MATA-37044 as drop-in alternatives solely from similar descriptions. The verified material does not provide a common package, complete pinout, control interface, or electrical-limit comparison. Obtain controlled documentation for every ordering variant and verify channel count, line-rate support, power rails, control polarity, output levels, LOS behavior, and footprint before replacement approval.
Account for four-channel coupling while laying out recovered data and clock outputs. Keep output traces matched where channel-to-channel skew matters, provide solid return paths beneath high-speed traces, and separate sensitive TIA inputs from switching or high-current paths. The provided evidence does not state supported output edge rates, output impedance, or isolation, so post-layout simulation and measured eye-margin testing are required before production release.
Plan supply routing only after obtaining the device's verified supply-voltage tolerance, startup behavior, current per channel, and package thermal data. Estimated: total dissipated power equals supply voltage multiplied by total supply current minus external delivered power; because all inputs are unavailable, no numerical estimate is provided. Use adequate local decoupling and verify that four-channel operation does not create unacceptable supply droop or thermal loading.
