Product details
Overview
DS4160D+ from Maxim Integrated is a 160MHz LVDS-output ceramic surface-mount crystal oscillator with ±50ppm frequency stability, <0.7psRMS phase jitter (12kHz–20MHz), and 3.3V ±5% supply operation. It uses a fundamental AT-cut crystal and integrated PLL to generate precise clock signals for high-speed serial interfaces requiring low jitter and tight timing margins.
For engineers reviewing the DS4160D+ datasheet, DS4160D+ pinout, DS4160D+ application, or DS4160D+ equivalent, this device is selected for systems where deterministic jitter performance, differential signaling integrity, and compact 5.0mm × 3.2mm footprint are critical - especially in optical transport, Ethernet PHY clocking, and SONET/SDH line cards.
Technical Context
The DS4160D+ integrates a BiPOLAR SiGe synthesizer IC with an AT-cut fundamental-mode crystal to generate 160MHz output via internal PLL multiplication. Its architecture supports active-high OE control with internal 100kΩ pull-up, enabling deterministic tri-state behavior on both LVDS outputs (OUTP/OUTN).
It operates exclusively with LVDS differential signaling - not LVPECL - delivering 250–425mV differential voltage into 100Ω load, with 175ps typical rise/fall time and 45–55% duty cycle. Phase noise at 10MHz offset is –149dBc/Hz, consistent across the DS4-XO family at 160MHz nominal frequency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency | 160.00MHz - fixed nominal frequency, no programmability; used as primary system clock source |
| Frequency Stability | ±50ppm total - covers temperature, aging, supply, and load variation; ensures timing margin compliance over full industrial range |
| Phase Jitter (12kHz–20MHz) | <0.7psRMS - meets OC-192/STM-64 and 10GbE IEEE 802.3ae jitter budgets |
| Supply Voltage | 3.3V ±5% - requires stable LDO regulation; ICC typically 52mA (LVDS unloaded) |
| Operating Temperature | –40°C to +85°C - qualified for industrial and telecom infrastructure environments |
| Output Type | LVDS - differential 100Ω-terminated interface; VOD = 250–425mV, common-mode = 1.125–1.275V |
| Package | 5.0mm × 3.2mm × 1.49mm, 10-pin LCCC - RoHS-compliant ceramic SMT package with exposed paddle (not connected) |
Pinout & Package
DS4160D+ is housed in a 5.0mm × 3.2mm × 1.49mm, 10-pin LCCC ceramic surface-mount package with exposed paddle (EP) that must remain unconnected and isolated from metal under the pad. Pin 1 is OE (active-high output enable); pins 2,7–10 are no-connect; pins 3 (GND), 4 (OUTP), 5 (OUTN), and 6 (VCC) define the functional interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE | Active-high output enable with internal 100kΩ pull-up; drives OUTP/OUTN to valid LVDS logic when HIGH |
| 2, 7–10 | N.C. | No connection - must be left floating; no internal circuitry attached |
| 3 | GND | Ground reference for all internal circuitry and output drivers; requires low-inductance PCB return path |
| 4 | OUTP | Positive LVDS output terminal; pairs with OUTN to deliver 250–425mV differential swing into 100Ω load |
| 5 | OUTN | Negative LVDS output terminal; complementary to OUTP; defines differential signaling polarity |
| 6 | VCC | 3.3V ±5% power supply input; decoupling requires 0.01μF + 0.1μF capacitors per datasheet layout guidance |
| EP | Exposed Paddle | Thermal pad only - electrically isolated; must not be soldered or connected to any net |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low phase jitter | <0.7psRMS (12kHz–20MHz) enables compliance with stringent 10GbE and SONET OC-192 timing masks |
| LVDS output interface | Guaranteed 250–425mV differential voltage and 175ps edge rates ensure signal integrity on FR4 backplanes |
| Industrial temperature range | –40°C to +85°C operation validated across full voltage and load conditions per datasheet test plan |
| RoHS-compliant ceramic LCCC | 5.0mm × 3.2mm footprint saves >40% board area vs. legacy 7.0mm × 5.0mm oscillators; lead finish Au over Ni (JESD97 e4) |
| Integrated OE control | Internal 100kΩ pull-up eliminates external bias resistor; simplifies power sequencing and hot-swap enable/disable |

Equivalent & Alternatives
The following parts are listed as comparable options for similar crystal oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si510-160M000000 | 160MHz, ±20ppm stability, 0.4psRMS jitter (12kHz–20MHz), 3.3V LVDS, same 5×3.2mm package | Higher stability and lower jitter; requires external configuration EEPROM; not drop-in compatible due to I²C setup requirement | Select for tighter timing budgets where programmability justifies added design complexity |
| AK2-160.000MHZ-E | 160MHz, ±50ppm stability, 0.8psRMS jitter (12kHz–20MHz), 3.3V LVDS, 5.0×3.2mm 6-pin SMD | Different pinout (6-pin vs. 10-pin), no OE pin, fixed enable; lower cost but lacks output control flexibility | Select for cost-sensitive, always-on clocking where OE functionality is unnecessary |

FAQ
What output type does the DS4160D+ support?
The DS4160D+ supports LVDS (Low-Voltage Differential Signaling) output only. It is not compatible with LVPECL; the 'D+' suffix explicitly denotes the LVDS variant. The device delivers 250–425mV differential voltage into a 100Ω load, with defined common-mode voltage (1.125–1.275V) and 175ps typical edge rates - all verified per the DS4125–DS4776 datasheet electrical characteristics table.
What is the frequency stability specification for DS4160D+?
The DS4160D+ has a total frequency stability of ±50ppm over its full operating range, covering temperature variation (–40°C to +85°C), aging (15-year), supply voltage change (±5%), and load variation (±10%). This value is explicitly listed in the Selector Guide and Electrical Characteristics tables for DS4160D+, and applies to the 160.00MHz nominal output.
Does DS4160D+ include an output enable function?
Yes, DS4160D+ includes an active-high output enable (OE) pin (Pin 1) with an internal 100kΩ pull-up resistor. When OE is driven LOW, the LVDS outputs enter high-impedance state; when HIGH, they drive valid differential logic. Propagation delays tP1A and tPA1 are both specified at 200ns maximum, ensuring predictable timing during enable/disable transitions.
What package type and dimensions does DS4160D+ use?
DS4160D+ uses a 10-pin LCCC (Leadless Chip Carrier) ceramic surface-mount package measuring 5.0mm × 3.2mm × 1.49mm. The package includes an exposed paddle (EP) that must remain unconnected and free of underlying metal - a requirement confirmed in the Pin Description section and Package Information page of the DS4125–DS4776 datasheet.
Is DS4160D+ RoHS compliant and lead-free?
Yes, DS4160D+ is RoHS compliant and lead-free. The '+' suffix indicates JESD97 category e4 termination (gold over nickel), compatible with both lead-based and lead-free soldering processes. This is documented in the Ordering Information, Packaging, and Chip Information sections of the official Maxim Integrated DS4125–DS4776 datasheet.
