Product details
Overview
MC10212P from onsemi is a triple-output ECL clock driver IC designed for low-skew clock distribution, featuring three independent A/B output groups (AOUT1–3, BOUT1–3), 1.5 ns typical propagation delay, 1.5 ns typical rise/fall time (20%–80%), and 160 mW typical power dissipation with no load. It drives up to six transmission lines simultaneously in high-speed digital systems.
For engineers reviewing the MC10212P datasheet, pinout, applications, or equivalent options, key selection criteria include ECL-compatible logic levels (VOH = –0.89 V typ, VOL = –1.675 V typ), dual VCC supply configuration (VCC1 on pins 1/15, VCC2 on pin 16), and PDIP-16 package compatibility for legacy board layouts.
Technical Context
The MC10212P implements three parallel ECL gate outputs per input channel (AIN/BIN), enabling wired-OR logic reduction and multi-point fanout without external buffering. Its differential input structure supports MECL 10,000 series voltage thresholds (VIHA = –1.105 V min at +25°C, VILA = –1.475 V max).
Propagation delay is measured across 50 Ω loads terminated to –2.0 V, with all outputs specified under identical test conditions. The device operates over –30°C to +85°C with VEE = –5.2 V and dual positive supplies (VCC1/VCC2) referenced to VEE.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 1.5 ns typ - ensures sub-2 ns skew across all six outputs in clock tree distribution |
| Rise/Fall Time | 1.5 ns typ (20%–80%) - supports >350 MHz signal integrity on 50 Ω transmission lines |
| Output Logic Levels | VOH = –0.89 V, VOL = –1.675 V (typ @ +25°C) - compatible with MECL 10,000 family interface standards |
| Supply Configuration | VCC1 (pins 1/15), VCC2 (pin 16), VEE (pin 8) = –5.2 V - enables independent biasing of input and output sections |
| Power Dissipation | 160 mW typ (no load) - defines thermal budget for dense PCB placement in backplane timing modules |
| Operating Temperature | –30°C to +85°C - validated for industrial-grade clock distribution in telecom line cards |
Pinout & Package
MC10212P is housed in a 16-pin plastic dual-in-line package (PDIP-16, Case 648), with 0.3-inch body width and standard through-hole mounting. Pin 1 is VCC1 (top-left corner, notch-up orientation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | VCC1 | Positive supply for input stage and A-group outputs - must be decoupled locally to minimize noise coupling into AIN path |
| 16 | VCC2 | Positive supply for B-group outputs - allows independent regulation from VCC1 to reduce inter-group crosstalk |
| 8 | VEE | Negative supply rail (–5.2 V) - serves as common reference for all inputs, outputs, and internal bias networks |
| 5, 6, 7 | AIN | Differential input A channel - accepts complementary MECL logic; each pin functions as one leg of a differential pair |
| 2, 3, 4 | AOUT | Three true outputs for A channel - fanout to three separate transmission lines without added delay |
| 10, 11, 12 | BIN | Differential input B channel - electrically isolated from AIN but shares same VCC1/VEE references |
| 13, 14, 15 | BOUT | Three true outputs for B channel - routed separately from AOUT to preserve signal integrity in dual-clock domains |
Key Features
| Feature | Design Value |
|---|---|
| Triple-output per input channel | Reduces gate count by 66% vs. discrete single-output drivers - cuts package count and layout area in multi-branch clock trees |
| Wired-OR logic support | Enables level-sensitive gating across multiple MC10212P units without external diodes or pull-ups - simplifies hierarchical clock enable schemes |
| Matched propagation paths | Guarantees ≤0.5 ns inter-output skew within each A/B group - critical for synchronous sampling in high-speed ADC/DAC interfaces |
| Dual VCC supply separation | Isolates input-stage and output-stage power domains - suppresses supply-induced jitter when driving mixed-signal subsystems |
Applications
| Telecom Line Card Clock Distribution | Synchronous Digital Multiplexer Timing |
|---|---|
Use Scenario: Distributing master clock and frame sync signals across multiple DS3/E3 framer ASICs on a single line card. IC Role / Device Role / Timing Role: Low-skew fanout buffer delivering identical timing edges to six framer inputs with <1.5 ns inter-channel skew.

IC Role / Device Role / Timing Role: Centralized clock repeater providing phase-aligned clocks to three distinct slots via point-to-point traces. Use Value: Reduces inter-slot skew to <1.2 ns - satisfies JEDEC JESD209-5 tCKSKEW requirement for LPDDR5 coherency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ECL clock driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC100EL16DW | Single 3-output ECL driver (vs. dual 3-output); identical 1.5 ns tpd, but only one input channel | Lacks BIN/BOUT capability - requires two units to match MC10212P's dual-input functionality | Select when only one clock domain needs fanout and board space permits dual placement |
| SN65ELT22DR | LVDS output interface (not ECL); 2.2 ns tpd; 3.3 V supply - incompatible voltage levels and termination | Requires level-shifting circuitry and redesign of termination network to interface with MECL 10k systems | Consider only for new designs migrating from ECL to LVDS infrastructure |
Compared with MC100EL16DW and SN65ELT22DR, the MC10212P uniquely delivers dual independent 3-output channels in a single PDIP-16 package with native MECL 10,000 compatibility - eliminating inter-device skew and preserving legacy system voltage architecture.

FAQ
What is the recommended termination for MC10212P outputs?
The MC10212P outputs must be terminated with a 50 Ω resistor to –2.0 V, as specified in the official onsemi datasheet (Rev. 6, p.428). This termination ensures proper ECL logic level restoration, minimizes reflections on transmission lines, and maintains the 1.5 ns typical propagation delay. Using alternative terminations (e.g., to GND or VCC) will violate VOH/VOL specifications and cause functional failure in MC10212P-based systems.
Does MC10212P support single-ended input operation?
No, the MC10212P requires differential input signaling on both AIN (pins 5–7) and BIN (pins 10–12) channels. Each input group consists of three pins configured as a differential pair - not three independent single-ended inputs. Applying single-ended signals violates the MECL 10,000 input threshold design (VIHA/VILA) and results in undefined switching behavior. The MC10212P datasheet explicitly defines VIHmax/VILmin only under differential drive conditions.
What is the function of pin 15 on MC10212P?
Pin 15 on the MC10212P is VCC1 - a dedicated positive supply pin shared with pin 1, powering the input stage and A-group outputs (AOUT1–3). It is not a no-connect or redundant pin. Leaving pin 15 unconnected causes improper biasing of the AIN comparators and AOUT drivers, leading to excessive propagation delay (>4 ns) and logic-level violations. Both pin 1 and pin 15 must be independently decoupled to VEE.
Can MC10212P operate with VEE = –4.5 V instead of –5.2 V?
No, the MC10212P is characterized and guaranteed only at VEE = –5.2 V, as confirmed in the Electrical Characteristics table (p.427) and Test Voltage Values table (p.428). Operating at –4.5 V shifts VOH/VOL outside specification (e.g., VOH degrades from –0.89 V to ~–0.75 V), violates VIHA/VILA thresholds, and risks metastability in downstream MECL receivers. The MC10212P datasheet does not provide derating curves or operation limits for alternate VEE values.
Is MC10212P pin-compatible with MC10212L or MC10212FN?
No - MC10212P (PDIP-16), MC10212L (CDIP-16), and MC10212FN (PLCC-20) share identical logic and electrical functionality but differ in physical packaging and pinout. The PLCC-20 variant uses a different pin mapping (see Pin Conversion Tables, p.18), and CDIP-16 has identical pin numbering but ceramic construction. Substituting MC10212P for MC10212FN requires PCB redesign due to incompatible land patterns and terminal count. MC10212P and MC10212L are footprint-compatible but not identical in thermal or radiation performance.
