Product details
Overview
DS3150QNC1/T&R from Maxim Integrated is a 3.3V, 28-pin PLCC line interface unit (LIU) performing full physical-layer interfacing for DS3 (44.736 Mbps), E3 (34.368 Mbps), and STS-1 (51.840 Mbps) telecom lines. It integrates receiver (clock/data recovery, B3ZS/HDB3 decoding, LOS detection), transmitter (B3ZS/HDB3 encoding, waveshaping, 75Ω coaxial drive), and configurable jitter attenuator - all in a single IC used in SONET/SDH multiplexers and DSLAMs.
For engineers reviewing the DS3150QNC1/T&R datasheet, DS3150QNC1/T&R pinout, DS3150QNC1/T&R application, or DS3150QNC1/T&R equivalent, key selection criteria include its dual-format (NRZ/bipolar) framer interface, adaptive equalizer supporting up to 15dB cable loss, ANSI T1.231/ITU G.775-compliant LOS detection, and drop-in compatibility with TDK 78P7200 in industrial-temperature (-40°C to +85°C) PLCC packaging.
Technical Context
The DS3150QNC1/T&R implements independent receive and transmit data paths with a shared jitter attenuator that can be routed into either path or disabled. Its receiver includes analog loss-of-signal (ALOS) and digital loss-of-signal (DLOS) detectors meeting ANSI T1.231 and ITU-T G.775 requirements, plus an adaptive equalizer compensating 0–15dB coaxial loss across DS3/E3/STS-1 rates.
The transmitter supports both NRZ and bipolar input formats, performs B3ZS (DS3/STS-1) or HDB3 (E3) encoding, drives standards-compliant waveforms onto 75Ω coaxial cable per ANSI T1.102, Telcordia GR-253-CORE, and ITU-T G.703, and includes line build-out (LBO) control and transmit driver monitor (DM) functionality.
Key Specifications

Pinout & Package
DS3150QNC1/T&R is housed in a 28-pin plastic leaded chip carrier (PLCC) package with J-leads, optimized for thermal performance and mechanical reliability in telecom infrastructure applications. Pin assignments are defined per Maxim's DS3150 datasheet revision 071305, Section 2 (Pin Descriptions) and Section 4 (Pin Configurations).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RX+, RX- | Differential receive input | Accepts transformer-coupled B3ZS/HDB3 AMI signals from 75Ω coaxial line; supports monitoring via RMON preamp mode. |
| TX+, TX- | Differential transmit output | Drives standards-compliant DS3/E3/STS-1 waveforms onto 75Ω coaxial cable; tri-state capable via TTS control. |
| RCLK, TCLK | Receive/transmit clock I/O | Provides recovered clock output (RCLK) and accepts transmit clock input (TCLK); polarity invertible via ICE pin for glueless framer interfacing. |
| RPOS/RNEG or RNRZ | Recovered data output | Selectable NRZ (RNRZ) or bipolar (RPOS/RNEG) format via ZCSE pin - enables direct connection to framer ASICs with matching interface logic. |

| MCLK | Master clock input | 44.736/34.368/51.840 MHz reference; selected as primary clock source when toggling - required for jitter attenuator operation in transmit path. |
Key Features
| Feature | Design Value |
|---|---|
| B3ZS/HDB3 encoder/decoder | Hardware-accelerated coding per ANSI T1.107 and ITU-T G.703 - eliminates need for external logic or FPGA-based encoding/decoding. |
| On-chip PRBS generator/detector | Supports 2¹⁵−1 and 2²³−1 patterns compliant with ITU O.151 - enables in-system physical-layer loopback testing without external test equipment. |
| AGC/equalizer with 0–15dB range | Automatically adapts to varying coaxial cable lengths and losses - removes manual gain calibration and supports field-deployable plug-and-play operation. |
| Transmit driver monitor (DM) | Asserts fault flag on load impedance <25Ω - detects shorted outputs or failed transformers early, improving system reliability and diagnostics. |
| Line build-out (LBO) control | Switches between preattenuated (short cable) and full-amplitude (long cable) drive - ensures waveform template compliance across 0–450 ft installations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar line interface unit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS3150TN | Same core functionality, but in 48-pin TQFP package with additional DM pin and extended thermal pad - no PLCC footprint compatibility. | Preferred for new designs requiring higher I/O density, better thermal dissipation, or transmit driver monitoring capability. | Select DS3150TN only if TQFP layout and DM functionality are required; not a drop-in replacement for DS3150QNC1/T&R. |
| TDK 78P7200 | Pin-compatible predecessor with identical 28-pin PLCC layout and overlapping DS3/E3 feature set - lacks STS-1 support and integrated jitter attenuator. | Suitable for legacy DS3/E3-only systems where STS-1 capability and jitter management are unnecessary. | Choose TDK 78P7200 only for cost-sensitive brownfield upgrades where STS-1 and jitter attenuation are unused. |
Compared with DS3150TN and TDK 78P7200, the DS3150QNC1/T&R uniquely delivers STS-1 support, programmable jitter attenuation, and industrial temperature operation in the compact 28-pin PLCC form factor - making it optimal for space-constrained, multi-standard telecom line cards requiring field-proven reliability.

FAQ
What telecom standards does the DS3150QNC1/T&R comply with?
The DS3150QNC1/T&R complies with ANSI T1.102, T1.107, T1.231, T1.404; ITU-T G.703, G.751, G.775, G.823, G.824; ETSI ETS 300 686/687/EN 300 689; and Telcordia GR-253-CORE and GR-499-CORE. These cover DS3/E3/STS-1 electrical interfaces, AIS generation, jitter tolerance/transfer, and LOS detection - all verified per Maxim's datasheet revision 071305.
Does the DS3150QNC1/T&R support both NRZ and bipolar framer interfaces?
Yes, the DS3150QNC1/T&R supports both NRZ and bipolar framer interfaces via the ZCSE pin. When ZCSE = low, the B3ZS/HDB3 decoder/encoder is active and data appears on RNRZ (receive) or TNRZ (transmit). When ZCSE = high, the device operates in bipolar mode with RPOS/RNEG and TPOS/TNEG pins - bypassing coding and enabling direct pulse-level interfacing as documented in Section 1.1 and 1.2 of the DS3150 datasheet.
What is the maximum coaxial cable length supported by the DS3150QNC1/T&R?
The DS3150QNC1/T&R supports up to 380 meters for DS3, 440 meters for E3, and 360 meters for STS-1 over AT&T 734A-equivalent 75Ω coaxial cable. This is enabled by its adaptive equalizer, which automatically compensates for 0–15dB of cable loss - a specification confirmed in the "Adaptive Equalizer" subsection of Section 1.1 in the DS3150 datasheet.
Is the DS3150QNC1/T&R pin-compatible with any legacy devices?
Yes, the DS3150QNC1/T&R is pin-compatible with TDK 78P7200, as stated in the "Features" section of the DS3150 datasheet. It is also a drop-in replacement for TDK 78P2241/B per Application Note 362. Both share the same 28-pin PLCC footprint, power sequencing, and core signal mapping - though DS3150QNC1/T&R adds STS-1 support and jitter attenuation not present in those predecessors.
What diagnostic capabilities does the DS3150QNC1/T&R provide?
The DS3150QNC1/T&R provides on-chip PRBS generation (2¹⁵−1 and 2²³−1) and detection per ITU O.151, local/remote loopback modes, transmit driver monitor (DM) output, and comprehensive LOS reporting via the LOS pin. These features enable full physical-layer validation without external test gear - as detailed in Section 1.3 ("Diagnostics") and Table 2-C of the DS3150 datasheet.
