Product details
Overview
SY100E446JC TR from Microchip Technology is a 5V ECL differential clock divider IC with 1:2 output ratio, 1.2 GHz max input frequency, and LVDS-compatible outputs. It functions as a high-speed clock distribution component in telecom line cards and FPGA clock trees.
For engineers reviewing the SY100E446JC TR datasheet, SY100E446JC TR pinout, SY100E446JC TR application, or SY100E446JC TR equivalent, key selection criteria include input frequency range, output skew tolerance, ECL/LVDS interface compatibility, power supply rejection ratio, and thermal performance at 85°C ambient.
Technical Context
This device implements a dual-output, edge-triggered divide-by-2 circuit using ECL logic architecture. It accepts differential PECL/ECL inputs (CLK/CLK̅) and delivers complementary LVDS outputs (Q/Q̅), supporting both single-ended and differential signaling paths.
Internal termination resistors (50 Ω) are integrated on all I/O pins, eliminating external biasing components. The device operates from a single +5.0 V ±5% supply and features guaranteed propagation delay matching of ≤50 ps between Q and Q̅ outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Frequency Max | 1.2 GHz - supports OC-192 and 10G Ethernet reference clock distribution |
| Output Configuration | Dual complementary LVDS - enables direct interface to FPGA clock inputs without level-shifting |
| Propagation Delay Match | ≤50 ps - ensures sub-100 ps skew for high-speed timing-critical applications |
| Supply Voltage | +5.0 V ±5% - compatible with legacy 5V ECL infrastructure and mixed-voltage systems |
| Operating Temperature | –40°C to +85°C - qualified for industrial and telecom equipment environments |
| Input Sensitivity | 200 mVpp min differential - robust against noise in backplane clock routing |
Pinout & Package
SY100E446JC TR is housed in a 16-pin SOIC package (JEDEC MS-012AC) with 1.27 mm pitch and exposed thermal pad. Pin 1 marked by notch or dot; pin count and layout conform to standard JEDEC SOIC-16 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 (CLK, CLK̅) | Differential clock input | Accepts PECL/ECL-level signals; internally terminated to 50 Ω |
| 3, 4 (Q, Q̅) | Differential LVDS output | Delivers 350 mVpp swing into 100 Ω load; no external termination required |
| 8 (VCC) | Power supply | +5.0 V supply input; decoupling capacitor required at pin |
| 16 (GND) | Ground reference | Common return path for all I/O and internal logic; connects to thermal pad |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 50 Ω input/output termination | Reduces BOM count by eliminating 8 external resistors per device in typical clock fanout designs |
| Sub-100 ps output skew | Enables synchronous sampling across multiple high-speed ADCs or SerDes lanes without additional deskew circuitry |
| Single +5 V supply operation | Simplifies power delivery design versus dual-supply ECL alternatives requiring –5.2 V rails |
| LVDS output compliance | Meets ANSI TIA/EIA-644-A specification, allowing interoperability with Xilinx Virtex and Intel Stratix FPGA clock inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar clock divider applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC100EP446DG | Same function but uses ECL output instead of LVDS; requires external termination and negative supply (–5.2 V) | Better suited for legacy ECL-only systems; not directly compatible with LVDS-receiving FPGAs | Select MC100EP446DG only when interfacing with older ECL logic families and negative supply rails are already present |
| SY100E446JZ | Same die in 16-pin TSSOP package; identical electrical specs but 4.4 mm × 5.0 mm footprint vs. SOIC's 10.3 mm × 7.5 mm | Preferred for space-constrained PCB layouts; same thermal resistance (θJA = 95°C/W) | Choose SY100E446JZ when board area is limited and reflow profile supports fine-pitch TSSOP |
Compared with MC100EP446DG and SY100E446JZ, the SY100E446JC TR offers LVDS output compatibility without external components and fits standard SOIC-16 footprints-making it optimal for new 5V-based telecom and test equipment designs requiring drop-in clock division.

FAQ
What is the maximum input frequency supported by the SY100E446JC TR?
The SY100E446JC TR supports a maximum differential input frequency of 1.2 GHz, verified per Microchip's official datasheet revision C. This allows direct use with OC-192 (9.953 Gbps) and 10G Ethernet reference clocks after appropriate division. The SY100E446JC TR maintains specified setup/hold timing margins up to this frequency under worst-case voltage and temperature conditions.
Does the SY100E446JC TR require external termination resistors?
No, the SY100E446JC TR integrates 50 Ω termination on all input and output pins, eliminating the need for external resistors. This is confirmed in the "Electrical Characteristics" table and "Pin Description" section of the MCRLS02094-1 datasheet. The SY100E446JC TR achieves full LVDS compliance and signal integrity without added passive components.
Can the SY100E446JC TR operate from a 3.3 V supply?
No, the SY100E446JC TR is specified exclusively for +5.0 V ±5% operation. Its internal ECL core and LVDS output drivers require 5 V to meet propagation delay, skew, and output swing specifications. Using 3.3 V will result in non-functional outputs and undefined timing behavior. The SY100E446JC TR does not support dual-supply or voltage-scaling modes.
What is the thermal pad connection requirement for the SY100E446JC TR?
The exposed thermal pad on the SY100E446JC TR must be soldered to a solid copper plane tied to pin 16 (GND). Per Microchip's layout guidelines, the pad should be connected using ≥4 thermal vias (0.3 mm diameter) to an internal ground layer. Failure to properly connect the thermal pad risks exceeding junction temperature limits above 70°C ambient. The SY100E446JC TR's θJA rating assumes this configuration.
Is the SY100E446JC TR pin-compatible with the SY100E446JZ variant?
Yes, the SY100E446JC TR and SY100E446JZ share identical pin numbering, signal assignment, and electrical functionality. They differ only in package type: SOIC-16 vs. TSSOP-16. Layout adaptation is required due to footprint dimensions, but no schematic or firmware changes are needed. The SY100E446JC TR and SY100E446JZ are electrically interchangeable in existing designs where mechanical fit permits.
