Product details
Overview
SN65LVCP23PW from Texas Instruments is a 2×2 LVPECL crosspoint switch IC supporting gigabit-speed signal routing in redundant serial bus systems. It accepts LVDS, LVPECL, and CML inputs; provides dual LVPECL outputs; delivers 1.3 Gbps data rate, <10 ps typical channel-to-channel skew, and 50 ps peak-to-peak jitter with 223–1 PRBS at 3.3 V supply. It enables protection switching in optical networking line cards and base station backplanes.
For engineers reviewing the SN65LVCP23PW datasheet, SN65LVCP23PW pinout, SN65LVCP23PW application, or SN65LVCP23PW equivalent, this page delivers verified electrical parameters, TSSOP-16 package details, functional configuration modes (2:1 mux, 1:2 demux, repeater, splitter), and real-world deployment context for fault-tolerant serial transmission paths.
Technical Context
The SN65LVCP23PW implements a fully differential data path with wide common-mode input range (0 V to 4 V), enabling interoperability across LVDS, LVPECL, and CML signaling standards. Its dual independent channels support simultaneous output operation with sub-nanosecond propagation delay (750 ps typ) and fast switching (1.7 ns typ).
Configuration is controlled via four logic inputs (EN0, EN1, SEL0, SEL1), allowing dynamic selection between 2:2 buffering, 2:1 multiplexing, 1:2 demultiplexing, and signal splitting. Output drivers are LVPECL-compliant with VOD = 600–1000 mV and termination to VTT = VCC – 2 V.

TSSOP-16 package (PW), 5.0 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm max height, RoHS-compliant NIPDAU finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SEL1) | Configuration select input | Controls crosspoint routing state with SEL0; defines active channel pair in 2:2 mode |
| 2 (SEL0) | Configuration select input | LSB of 2-bit select bus; jointly determines IN0/IN1 → OUT0/OUT1 mapping per function table |
| 3 (IN0+) | Differential input positive | Accepts LVDS/LVPECL/CML signals; common-mode range 0–4 V enables direct interface without AC coupling |
| 4 (IN0–) | Differential input negative | Paired with IN0+; differential threshold ±100 mV with 25 mV hysteresis for noise immunity |
| 5 (VCC) | Power supply | 3.3 V core supply; decoupling required near pin due to 65 mA typical ICCD current draw |
| 6 (IN1+) | Differential input positive | Second independent receiver channel; electrically identical to IN0+, supports dual-input redundancy |
| 7 (IN1–) | Differential input negative | Complements IN1+; supports full-duplex or mirrored input paths in protection switching architectures |
| 8 (VCC) | Power supply | Second VCC connection; improves power integrity for high-frequency LVPECL output stage |

| 12 (OUT0–) | LVPECL output negative | Complementary to OUT0+; differential swing 600–1000 mV meets LVPECL DC specifications |
| 13 (GND) | Ground reference | Analog/digital ground plane connection; requires low-inductance return path for jitter control |
| 14 (OUT1+) | LVPECL output positive | Second LVPECL driver; matched delay and skew to OUT0 for synchronous dual-output applications |
| 15 (OUT1–) | LVPECL output negative | Paired with OUT1+; supports independent routing to two downstream receivers or clock domains |
| 16 (GND) | Ground reference | Secondary ground pin; reduces ground bounce between output stages during simultaneous switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed crosspoint switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVCP22PW | 2×2 LVDS crosspoint (not LVPECL); lower 1.0 Gbps max data rate; 15 ps skew (typ) | Targeted at LVDS-only systems (e.g., camera links); lacks LVPECL output drive strength and CML input support | Select when interfacing exclusively with LVDS sources/sinks and lower jitter tolerance is acceptable |
| LMH2190IRGET | 2×2 RF switch (DC–6 GHz); 50 Ω impedance; no integrated level translation or skew control | Used in RF front-end signal routing (e.g., antenna diversity), not baseband serial data paths | Choose only for analog RF signal switching; incompatible with digital serial protocols due to lack of DC coupling and logic control |
Compared with SN65LVCP22PW and LMH2190IRGET, the SN65LVCP23PW uniquely combines LVPECL output drive, multi-standard input acceptance, and sub-10 ps skew-making it irreplaceable in telecom line-card protection switching where signal integrity across voltage standards is mandatory.

FAQ
What is the maximum data rate supported by the SN65LVCP23PW?
The SN65LVCP23PW supports up to 1.3 Gbps with verified performance using a 223–1 PRBS test pattern. At this rate, it maintains 50 ps peak-to-peak jitter and meets LVPECL output specifications. Operation beyond 1.3 Gbps is not characterized in the official datasheet, and system-level validation would be required for higher rates.
Does the SN65LVCP23PW require external termination resistors?
Yes, the SN65LVCP23PW LVPECL outputs require 50 Ω termination to VTT = VCC – 2 V, as specified in Figure 2 of the datasheet. Input termination depends on source type: LVDS inputs need 100 Ω differential termination, while LVPECL/CML may require Thevenin or AC-coupled bias networks. No internal termination is provided.
Can the SN65LVCP23PW operate with a 2.5 V supply?
No. The SN65LVCP23PW is specified only for VCC = 3.0 V to 3.6 V. Operation at 2.5 V falls outside recommended conditions and risks failure to meet LVPECL output voltage levels (VOH/VOL), input threshold margins, and jitter specifications. TI does not characterize or guarantee functionality below 3.0 V.
How is channel-to-channel skew measured for the SN65LVCP23PW?
Channel-to-channel skew (tCCS) is measured in splitter mode with identical input applied to both IN0 and IN1, and outputs monitored simultaneously on OUT0 and OUT1. The datasheet specifies 10 ps typical and 50 ps maximum skew under 650 MHz sine-wave conditions, reflecting worst-case alignment error between duplicated signals.
Is the SN65LVCP23PW pin-compatible with the SN65LVCP23D (SOIC package)?
Yes, the SN65LVCP23PW (TSSOP-16) and SN65LVCP23D (SOIC-16) share identical pin numbering, signal assignment, and electrical behavior. Both packages implement the same logic function table and DC/AC specifications; only mechanical dimensions and thermal characteristics differ.
