Product details
Overview
DS3150QN from Maxim Integrated is a 3.3V, single-chip DS3/E3/STS-1 Line Interface Unit (LIU) performing physical-layer interfacing with integrated receiver, transmitter, and configurable jitter attenuator. It supports B3ZS/HDB3 decoding/encoding, clock/data recovery at 44.736Mbps (DS3), 34.368Mbps (E3), or 51.840Mbps (STS-1), and interfaces directly to 75Ω coaxial cable up to 380m (DS3). Used in SONET/SDH multiplexers and digital cross-connect systems.
For engineers reviewing the DS3150QN datasheet, DS3150QN pinout, DS3150QN application, or DS3150QN equivalent, key selection considerations include its 28-pin PLCC industrial-temperature package, dual-format (NRZ/bipolar) framer interface, built-in PRBS generator/detector, loss-of-signal compliance per ANSI T1.231 and ITU G.775, and drop-in compatibility with TDK 78P7200.
Technical Context
The DS3150QN implements independent receive and transmit data paths with a programmable jitter attenuator that can be placed in either path or disabled. Its adaptive equalizer compensates for 0–15dB coaxial cable loss, enabling operation over 380m (DS3), 440m (E3), or 360m (STS-1) using AT&T 734A-equivalent cable.
Receiver functionality includes analog and digital loss-of-signal detection per ANSI T1.231 and ITU G.775, automatic data squelching during LOS, and selectable NRZ/bipolar output via ZCSE control. Transmitter supports line build-out (LBO) control, transmit driver monitor (DM pin available only in TQFP), and standards-compliant waveshaping per ANSI T1.102, ITU G.703, and Telcordia GR-253-CORE.
Key Specifications

Pinout & Package
DS3150QN is housed in a 28-pin Plastic Leaded Chip Carrier (PLCC) package with J-lead configuration, designed for surface-mount assembly and thermal reliability in high-density telecom line cards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RX+, RX− | Differential line receiver inputs | Accept transformer-coupled B3ZS/HDB3 AMI signals from 75Ω coaxial cable; support monitoring via RMON preamp. |
| TX+, TX− | Differential line driver outputs | Drive standards-compliant waveforms onto 75Ω coaxial cable; tri-state capable via TTS for protection switching. |
| RCLK, TCLK | Receive/transmit clock outputs/inputs | RCLK carries recovered clock; TCLK clocks input data; both support polarity inversion via ICE for glueless framer interfacing. |
| RPOS/RNEG, TPOS/TNEG | Bipolar format I/O | Enable direct bipolar signaling without B3ZS/HDB3 decode/encode when ZCSE = high; used in legacy framer interfaces. |
| RNRZ, TNRZ | NRZ format I/O | Carry decoded (RNRZ) or encoded (TNRZ) data when ZCSE = low; integrate B3ZS (DS3/STS-1) or HDB3 (E3) logic on-die. |
| LOS | Loss-of-signal indicator | Open-drain output asserted during DLOS condition; meets ANSI/ITU timing and threshold requirements for alarm reporting. |
| MCLK | Master clock input | Selects primary timing source: internal oscillator (MCLK = low), TCLK (MCLK floating/high), or external reference (MCLK toggling). |
| ZCSE | Zero-code suppression enable | High = bipolar mode (decoder/encoder bypassed); low = NRZ mode (B3ZS/HDB3 active); determines framer interface protocol. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LIU architecture | Combines receiver, transmitter, and jitter attenuator in one die-eliminates discrete transceiver + clock cleanup + equalizer design complexity. |
| Standards-compliant waveform generation | Meets DS3/E3/STS-1 template specs per ANSI T1.102, ITU G.703, and Telcordia GR-253-CORE without external shaping components. |
| Configurable jitter attenuation path | Enables system-level jitter management flexibility-jitter attenuator can be routed into receive path (cleaning incoming jitter) or transmit path (cleaning outgoing jitter). |
| Direct DSX monitor interface | Built-in preamp accepts 20dB flat-loss DSX monitor signals-enables non-intrusive line monitoring without external gain stages. |
| On-chip diagnostics | Includes PRBS generator/detector, AIS pattern generation (DS3/E3), and transmit driver monitor-reduces test equipment dependency and accelerates field validation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar line interface unit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS3150T | Same core functionality but rated for 0°C to +70°C commercial temperature range; packaged in 48-pin TQFP. | Suitable for controlled-environment indoor equipment (e.g., enterprise routers); lacks industrial temp rating and PLCC form factor. | Select DS3150T only if ambient operating temperature stays within 0–70°C and PCB layout accommodates larger TQFP footprint. |
| TDK 78P7200 | Pin-compatible 28-pin PLCC LIU; supports DS3/E3 but lacks STS-1 mode and integrated jitter attenuator. | Used in legacy DS3/E3-only systems; requires external jitter cleanup for SONET applications. | Choose TDK 78P7200 only for cost-sensitive DS3/E3 upgrades where STS-1 support and jitter attenuation are not required. |
Compared with DS3150T and TDK 78P7200, the DS3150QN uniquely delivers industrial-temperature operation in compact 28-pin PLCC while supporting all three line rates (DS3/E3/STS-1) and offering configurable jitter attenuation-critical for next-generation multi-service access platforms requiring SONET interoperability and extended environmental resilience.

FAQ
What is the operating temperature range of the DS3150QN?
The DS3150QN is specified for industrial operation from –40°C to +85°C. This range enables deployment in uncontrolled environments such as outside plant cabinets, central office shelves, and transport network nodes where ambient temperatures exceed commercial limits. The DS3150QN maintains full electrical performance-including jitter tolerance, LOS detection timing, and equalizer adaptation-across this entire range, as verified per Telcordia GR-499 and ANSI T1.231 requirements.
Does the DS3150QN support both DS3 and STS-1 line rates?
Yes, the DS3150QN supports all three major TDM line rates: 44.736Mbps (DS3), 34.368Mbps (E3), and 51.840Mbps (STS-1). Its clock and data recovery block automatically adapts to the selected rate based on the master clock applied to MCLK (44.736MHz, 34.368MHz, or 51.840MHz). Waveform templates, jitter transfer, and LOS detection parameters are all validated per applicable standards-including ANSI T1.102, ITU G.703, and Telcordia GR-253-CORE-for each rate.
How does the jitter attenuator function in the DS3150QN?
The DS3150QN's jitter attenuator is a digitally controlled PLL-based circuit that can be mapped into either the receive path (to clean incoming jitter before CDR) or the transmit path (to clean outgoing jitter before waveshaping), or disabled entirely. When enabled in the transmit path, it derives the line clock from MCLK-allowing use of a lower-quality TCLK input. Performance meets GR-499 Category I/II and ITU G.823/G.824 specifications across all supported rates and temperature conditions.
What package type is used for the DS3150QN?
The DS3150QN uses a 28-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads. This surface-mount package offers robust thermal performance and mechanical reliability for high-vibration telecom environments. Its compact footprint (11.5mm × 11.5mm) and compatibility with standard PLCC reflow profiles make it ideal for dense line-card layouts in multiplexers and cross-connect systems.
Is the DS3150QN pin-compatible with any legacy line interface devices?
Yes, the DS3150QN is pin-compatible with the TDK 78P7200 LIU in its 28-pin PLCC variant. However, the DS3150QN adds STS-1 support, integrated jitter attenuation, and industrial temperature qualification not present in the TDK device. For migration from TDK 78P7200, no PCB redesign is needed-but firmware and configuration must be updated to leverage enhanced features like PRBS testing and configurable jitter path routing.
