Product details
Overview
DS90C032BTMX/NOPB from Texas Instruments is a quad LVDS differential line receiver supporting >155.5 Mbps (77.7 MHz) data rates, accepting 350 mV differential input signals, and delivering CMOS/TTL-compatible outputs with 6.0 ns maximum propagation delay and 600 ps maximum differential skew. It operates across −40°C to +85°C and features TRI-STATE enable control via EN/EN* pins for bus multiplexing in high-speed point-to-point interfaces.
For engineers reviewing the DS90C032BTMX/NOPB datasheet, DS90C032BTMX/NOPB pinout, DS90C032BTMX/NOPB application, or DS90C032BTMX/NOPB equivalent, key selection criteria include LVDS input compatibility, industrial temperature operation, failsafe behavior under open/terminated conditions, ultra-low power dissipation (3.5–11 mA ICC), and SOIC-16 surface-mount packaging.
Technical Context
The DS90C032BTMX/NOPB implements four independent LVDS receivers with high-impedance inputs compliant with ANSI/TIA/EIA-644, each featuring differential thresholds of ±100 mV and a ±1 V common-mode input range centered at +1.2 V. Its internal failsafe circuitry ensures HIGH output for both OPEN and externally biased 100 Ω-terminated inputs.
TRI-STATE functionality is implemented via dual enable inputs (EN active-high, EN* active-low, OR-ed logic), enabling precise channel gating without bus contention. Propagation delay variation is tightly controlled: channel-to-channel skew ≤1.5 ns over temperature, and differential skew ≤1.2 ns, ensuring timing integrity in multi-lane parallel links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | >155.5 Mbps (77.7 MHz) - supports high-bandwidth pixel clock and digital video transmission |
| Differential Input Threshold | ±100 mV - enables reliable detection of low-amplitude LVDS signals even with noise margin |
| Propagation Delay | ≤6.0 ns - ensures sub-10 ns timing alignment critical for synchronous parallel data capture |
| Differential Skew | ≤600 ps (25°C), ≤1.2 ns (−40°C to +85°C) - maintains inter-pair timing integrity in multi-channel systems |

Pinout & Package
DS90C032BTMX/NOPB is housed in a 16-pin SOIC package (Package Number D, R-PDSO-G16), with 1.27 mm pitch, 10.3 mm body width, and RoHS-compliant matte tin (Sn) lead finish. The device uses standard JEDEC SOIC footprint and is compatible with Level-1 MSL handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 9, 15 | RIN− | Inverting LVDS input for channels 1–4; requires matched trace length and 100 Ω termination near receiver |
| 2, 6, 10, 14 | RIN+ | Non-inverting LVDS input for channels 1–4; forms differential pair with corresponding RIN− |
| 3, 5, 11, 13 | ROUT | CMOS/TTL output (3.8–4.9 V VOH, 0.07–0.3 V VOL); drives standard logic loads directly |
| 4 | EN | Active-high enable; OR-ed with EN* - asserts TRI-STATE when low, enabling bus sharing |
| 12 | EN* | Active-low enable; OR-ed with EN - asserts TRI-STATE when high, supporting flexible control logic |
| 16 | VCC | +5 V supply pin; decoupling capacitor required within 1 cm for stable high-speed operation |
| 8 | GND | Analog/digital ground reference; must be low-impedance and tied to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Failsafe Operation | Guarantees HIGH output for OPEN inputs (internal bias) and 100 Ω-terminated inputs (with external bias resistors) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90LV032ATM/NOPB | 3.3 V supply only; lower 350 mV threshold; 2.5 ns max propagation delay | Designed for modern low-voltage systems; not 5 V tolerant | Select when migrating to 3.3 V infrastructure and requiring faster timing |
| SN65LVDS32DR | 3.3 V supply; integrated failsafe bias; 2.8 ns max propagation delay; same SOIC-16 package | Eliminates external bias resistors; optimized for plug-and-play LVDS links | Choose for simplified design where external biasing complexity must be avoided |
Compared with DS90C032BTMX/NOPB, DS90LV032ATM/NOPB offers higher speed but sacrifices 5 V compatibility, while SN65LVDS32DR reduces bill-of-materials count via integrated failsafe yet limits supply flexibility - DS90C032BTMX/NOPB remains optimal for robust 5 V industrial designs requiring field-proven reliability and explicit bias control.

FAQ
What is the supply voltage range for DS90C032BTMX/NOPB?
The DS90C032BTMX/NOPB operates from +4.5 V to +5.5 V, with recommended nominal supply at +5.0 V ±10%. This range ensures compatibility with standard 5 V logic systems while maintaining full specification compliance across temperature and load conditions. The device draws 3.5–11 mA no-load supply current depending on enable state and ambient temperature. DS90C032BTMX/NOPB does not support 3.3 V operation.
Does DS90C032BTMX/NOPB support failsafe operation with terminated inputs?
Yes, DS90C032BTMX/NOPB supports failsafe operation for both OPEN and 100 Ω-terminated inputs. For OPEN inputs, internal high-value pull-up/pull-down resistors force a HIGH output. For terminated inputs, external bias resistors are required to establish a defined differential voltage during driver power-off or disconnection. TI Application Note AN-1194 provides resistor calculation guidance for DS90C032BTMX/NOPB failsafe implementation.
What is the maximum channel-to-channel skew for DS90C032BTMX/NOPB?
The DS90C032BTMX/NOPB specifies a maximum channel-to-channel skew of 1.5 ns over the full operating temperature range (−40°C to +85°C). At +25°C, typical skew is 0.6 ns with a maximum of 1.0 ns. This tight skew performance ensures timing coherence across all four receiver channels in parallel data applications such as RGB video or multi-sensor interfaces.
Is DS90C032BTMX/NOPB pin-compatible with older PECL receivers?
Yes, DS90C032BTMX/NOPB is explicitly pin-compatible with DS26C32A, MB570 (PECL), and 41LF (PECL) receivers. Pin assignments for RIN+, RIN−, ROUT, EN, EN*, VCC, and GND match these legacy devices, enabling drop-in replacement in existing designs without PCB modification. However, DS90C032BTMX/NOPB uses LVDS signaling instead of PECL, requiring matching LVDS drivers like DS90C031B.
How does DS90C032BTMX/NOPB handle power-off conditions?
DS90C032BTMX/NOPB features power-off high-impedance LVDS inputs: when VCC = 0 V, the inputs present minimal loading to the LVDS bus, preventing interference with live drivers on shared lines. This behavior is intrinsic to the CMOS input structure and requires no external circuitry. Outputs remain in a high-impedance state during power-off, ensuring safe hot-plug and system-level power sequencing.
