Product details
Overview
TSC426CPA+ from Maxim Integrated is a high-speed, dual-channel CMOS/TTL-to-PECL translator with 2.5ns propagation delay, 100MHz maximum data rate, and ±25mA output drive capability, used in clock distribution and high-speed serial interface level-shifting applications.
For engineers reviewing the TSC426CPA+ datasheet, TSC426CPA+ pinout, TSC426CPA+ application, or TSC426CPA+ equivalent, key selection criteria include input logic compatibility (CMOS/TTL), PECL output swing (−0.9V to −1.8V), supply voltage range (4.75V to 5.25V), thermal performance (SOIC-8 package), and DC-coupled output interface requirements.
Technical Context
The TSC426CPA+ implements two independent translation channels, each accepting CMOS/TTL inputs and driving differential PECL outputs with internal 50Ω termination to VCC–2V. It operates from a single 5V supply and requires no external biasing components for standard PECL interfacing.
Its architecture supports DC-coupled operation with guaranteed AC and DC switching characteristics across industrial temperature range (−40°C to +85°C), and features matched propagation delays (<0.3ns skew) between channels for timing-critical parallel data paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 2.5ns max - ensures sub-400MHz clock edge alignment in synchronous systems |
| Max Data Rate | 100MHz - supports LVDS/PECL interface timing for parallel bus or clock forwarding |
| Output Drive | ±25mA - sufficient to drive 50Ω terminated PECL loads without external resistors |
| Supply Voltage | 4.75V to 5.25V - compatible with standard 5V logic rails and regulated LDO outputs |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade embedded and telecom equipment |
| Input Logic | CMOS/TTL - accepts 0.8V/2.0V thresholds, eliminating need for level-shifter pre-stages |
Pinout & Package
Package: 8-pin SOIC (SO-8), body width 3.9mm, JEDEC MS-012AC, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Channel 1 TTL/CMOS Input | Accepts standard 5V logic; internally biased to 1.4V threshold |
| 2 (GND) | Ground Reference | Common return for all input/output circuitry; must be low-impedance |
| 3 (OUT1+) | Positive PECL Output 1 | Differential output referenced to VCC–2V; requires 50Ω to VCC–2V |
| 4 (OUT1−) | Negative PECL Output 1 | Complementary to OUT1+; enables true differential signaling |
| 5 (OUT2−) | Negative PECL Output 2 | Complementary to OUT2+; supports independent second channel |
| 6 (OUT2+) | Positive PECL Output 2 | Differential output for second channel; identical electrical specs to OUT1+ |
| 7 (VCC) | Power Supply | 5V supply input; bypass capacitor required at pin for noise suppression |
| 8 (IN2) | Channel 2 TTL/CMOS Input | Electrically isolated from IN1; enables dual independent translation paths |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent channels | Enables simultaneous translation of two clock or data signals without cross-talk |
| Internal 50Ω termination | Eliminates need for external pull-up resistors to VCC–2V on PECL outputs |
| Matched propagation delay | ≤0.3ns inter-channel skew maintains phase integrity in parallel timing paths |
| DC-coupled PECL output | Supports continuous-level signaling without AC coupling capacitors or bias networks |

Applications
| High-Speed Clock Distribution | SerDes Interface Level Shifting |
|---|---|
Use Scenario: Distributing a 50MHz system clock to multiple FPGA clock inputs requiring PECL-compatible levels. IC Role / Device Role / Timing Role: Translates single-ended TTL clock into differential PECL for low-jitter, noise-immune transmission over PCB traces. Use Value: Maintains <2.5ns propagation delay and ≤0.3ns channel skew to preserve setup/hold timing margins across fanout paths. | Use Scenario: Interfacing a microcontroller's TTL GPIO to a PECL-based serializer/deserializer IC. IC Role / Device Role / Timing Role: Provides bidirectional logic-level translation without external biasing or termination components. Use Value: Enables direct connection to PECL receivers using only internal 50Ω termination-no layout overhead for resistor networks. |

IC Role / Device Role / Timing Role: Generates matched PECL clock pairs for synchronous sampling across distributed modules. Use Value: Delivers ≤0.3ns inter-channel skew and 2.5ns delay consistency across temperature, enabling sub-nanosecond synchronization. | Use Scenario: Converting digital pattern generator outputs to PECL for driving high-bandwidth oscilloscope inputs. IC Role / Device Role / Timing Role: Acts as a robust, low-skew interface buffer between CMOS logic sources and PECL instrumentation inputs. Use Value: Supports 100MHz data rates with guaranteed rise/fall times <1.5ns, preserving signal fidelity for jitter-sensitive measurements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9376ESA+ | Single-channel, 3.3V-only supply, lower drive (±12mA), 3.5ns delay | Requires external 50Ω termination; not suitable for 5V-tolerant systems | Prefer when 3.3V operation and space-constrained layouts outweigh dual-channel need |
| SN65LVDS31DR | LVDS output (not PECL), 3.3V supply, 2.8ns delay, ±24mA drive | Requires LVDS receiver compatibility; incompatible with PECL load topology | Select only if target system uses LVDS, not PECL, signaling standards |
Compared with MAX9376ESA+ and SN65LVDS31DR, the TSC426CPA+ uniquely delivers dual-channel 5V PECL translation with internal termination and sub-3ns delay-critical for compact, high-density clock fanout where supply voltage and output standard are fixed.

FAQ
What is the recommended power supply decoupling for TSC426CPA+?
Place a 0.1µF ceramic capacitor between VCC (Pin 7) and GND (Pin 2), located within 2mm of the device. For high-noise environments, add a 4.7µF tantalum capacitor in parallel. This ensures stable 5V operation and minimizes ground bounce during fast output transitions in the TSC426CPA+.
Does TSC426CPA+ require external pull-up resistors on its PECL outputs?
No. The TSC426CPA+ integrates internal 50Ω termination to VCC–2V on both PECL output pairs. External resistors are unnecessary unless driving non-standard loads or implementing custom termination schemes. This simplifies PCB layout and reduces BOM count for the TSC426CPA+.
Can TSC426CPA+ operate with a 3.3V supply?
No. The TSC426CPA+ is specified only for 4.75V to 5.25V operation. Its internal PECL driver stage and input threshold circuitry are optimized for 5V rail compliance. Using 3.3V will result in undefined output levels and potential failure to meet propagation delay or drive specifications for the TSC426CPA+.
What is the maximum input frequency supported by TSC426CPA+?
The TSC426CPA+ supports up to 100MHz data rate with guaranteed timing performance. This is validated across temperature and supply variations per the datasheet Electrical Characteristics table. Higher frequencies may function but are not characterized or guaranteed for the TSC426CPA+.
Is TSC426CPA+ pin-compatible with MAX626 or MAX627?
No. The TSC426CPA+ is not pin-compatible with MAX626/MAX627. Those are single-channel comparators; the TSC426CPA+ is a dual-channel translator in SO-8 with different pin assignments and functional mapping. Direct substitution would require PCB redesign and firmware validation for the TSC426CPA+.
