Product details
Overview
DS1088EX-133+T from Maxim Integrated is a factory-calibrated, fixed-frequency EconOscillator™ delivering a 133MHz square-wave clock output with ±1.0% frequency tolerance over voltage and temperature, 2.7V–3.6V supply operation, and active-low power-down control. It requires no external timing components and operates across –20°C to +85°C for embedded timing in space-constrained peripherals.
For engineers reviewing the DS1088EX-133+T datasheet, DS1088EX-133+T pinout, DS1088EX-133+T application, or DS1088EX-133+T equivalent, key selection criteria include guaranteed 133MHz output stability, µSOP-8 package compatibility, power-down current ≤10µA, load capacitance support up to 50pF, and factory-trimmed frequency accuracy without calibration overhead.
Technical Context
The DS1088EX-133+T integrates a voltage-controlled oscillator (80–160MHz range) followed by a programmable prescaler (÷1, ÷2, ..., ÷256) to generate its fixed 133MHz output. Its EEPROM stores factory-set division ratio and trim settings, enabling single-output clock generation without external crystals or capacitors.
Power management is implemented via the PDN pin: asserting low disables the VCO and output within ≤7ns, reducing supply current to ≤10µA; recovery requires ≥512 internal clock cycles (~3.8µs at 133MHz) plus stabilization delay. Output duty cycle is 40–60% for fO ≥80MHz and 50% typical at 133MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 133MHz - precisely factory-programmed, no external tuning required |
| Frequency Tolerance | ±1.0% over full voltage (2.7–3.6V) and temperature (–20°C to +85°C) range - eliminates system-level recalibration |
| Supply Voltage | 2.7V to 3.6V - compatible with 3.3V logic domains and low-power embedded rails |
| Power-Down Current | ≤10µA - enables ultra-low standby power in battery-backed or energy-sensitive systems |
| Output Load Drive | CL = 15pF to 50pF - supports standard CMOS loads without external buffering |
| Duty Cycle | 40–60% at 133MHz - meets setup/hold timing margins for synchronous logic interfaces |
| Power-Up Stabilization | ~3.8µs (512 cycles @ 133MHz) - defines minimum reset release timing after VCC ramp |
Pinout & Package
DS1088EX-133+T is housed in an 8-pin µSOP package (outline 21-0036), RoHS-compliant, with exposed pad not connected. Pin 1 is OUT; pins 2 and 3 are VCC; pins 4 and 5 are GND; pin 6 is PDN (active-low); pins 7 and 8 are DNC (internally grounded, must be left unconnected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Oscillator output | CMOS-compatible 133MHz square wave; drives 15–50pF loads directly |
| 2, 3 (VCC) | Power supply | Dual VCC pins reduce IR drop and improve PSRR; require local 0.01µF + 0.1µF ceramic decoupling |
| 4, 5 (GND) | Ground reference | Dual GND pins provide low-inductance return path; must connect to solid ground plane |
| 6 (PDN) | Active-low power-down control | Pull high (≥0.7×VCC) to enable; pull low (≤0.3×VCC) to disable output and enter ≤10µA standby |
| 7, 8 (DNC) | Do-not-connect terminals | Internally tied to GND; must remain unconnected on PCB to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed frequency | 133MHz output calibrated at wafer level - eliminates BOM cost and layout area for crystal + load caps |
| No external timing components | Self-contained oscillator core - removes risk of crystal aging, ESD sensitivity, and board-level tuning drift |
| Low-power shutdown mode | 10µA max ICCQ - enables dynamic clock gating in portable or always-on edge devices |
| Wide supply voltage range | 2.7V–3.6V operation - supports legacy 3.3V rails and newer low-voltage SoC interfaces |
| Stable duty cycle | 40–60% at 133MHz - ensures reliable sampling in DDR, USB, and PCIe clock domains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-frequency oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-133.000M | Programmable I²C-configurable XO; ±50ppm initial accuracy; 3.3V only; 7mA active current | Requires configuration firmware; supports frequency agility but adds startup latency | Choose when field-upgradable frequency or multi-rate operation is needed |
| ABM3B-133.000MHZ-D2Y-T | 133MHz fundamental-mode quartz crystal; requires external oscillator circuit; ±20ppm tolerance; 10pF load | Higher board-level component count; sensitive to layout parasitics and aging | Choose when lowest phase noise or long-term aging stability (<±5ppm/year) is critical |
Compared with Si510-133.000M and ABM3B-133.000MHZ-D2Y-T, DS1088EX-133+T offers lowest BOM count and fastest time-to-operate, trades off configurability and ultra-fine frequency resolution for guaranteed 133MHz accuracy with zero external components and sub-4µs wake-up.

FAQ
What is the exact output frequency of DS1088EX-133+T?
The DS1088EX-133+T is factory-programmed to deliver a nominal 133.000MHz square-wave output. Measured frequency variation is bounded by ±1.0% across the full operating voltage (2.7V–3.6V) and temperature (–20°C to +85°C) range, with typical deviation under ±0.3% at 25°C and 3.3V. This value is stored in on-chip EEPROM and cannot be modified in the field.
Does DS1088EX-133+T require external capacitors or resistors?
No, DS1088EX-133+T requires no external timing components. It integrates a factory-trimmed VCO and prescaler to generate its 133MHz output. Only two ceramic decoupling capacitors (0.01µF and 0.1µF) placed near VCC/GND pins are mandatory for stable operation - no load capacitors, pull-ups, or series resistors are needed on the OUT or PDN lines.
How does the power-down function work on DS1088EX-133+T?
The DS1088EX-133+T enters power-down mode when the PDN pin is driven low (≤0.3×VCC). Output disables within ≤7ns, and supply current drops to ≤10µA. To exit, PDN must be pulled high (≥0.7×VCC); the device then waits ~3.8µs (512 internal cycles at 133MHz) before enabling the output, ensuring VCO stabilization.
What is the recommended PCB layout for DS1088EX-133+T?
Place DS1088EX-133+T close to the load it clocks. Use dual 0.01µF and 0.1µF X7R ceramic capacitors between each VCC pin and the nearest GND pin, with short, wide traces. Keep OUT trace short and away from noisy signals. Leave pins 7 and 8 (DNC) unconnected - do not route or solder them. Ensure solid ground plane beneath the µSOP body.
Is DS1088EX-133+T pin-compatible with other DS1088L variants?
Yes, DS1088EX-133+T shares the same 8-pin µSOP package (U8+1 outline), pinout, and electrical interface as all DS1088L-series devices including DS1088LU-100+, DS1088LU-66+, and DS1088LU-16+. All variants use identical VCC, GND, OUT, PDN, and DNC pin assignments - only the factory-programmed output frequency differs.
