Product details
Overview
SN65LVCP23PWR from Texas Instruments is a 2×2 LVPECL crosspoint switch IC supporting 1.3 Gbps data rates, 650 MHz bandwidth, and dual-channel operation with <10 ps typical channel-to-channel skew. It accepts LVDS, LVPECL, and CML inputs and delivers LVPECL outputs for high-speed serial bus redundancy in optical networking line cards and protection switching systems.
For engineers reviewing the SN65LVCP23PWR datasheet, SN65LVCP23PWR pinout, SN65LVCP23PWR application, or SN65LVCP23PWR equivalent, key selection criteria include differential input voltage threshold (±100 mV), fast 1.7 ns typical switch time, 0.75 ns typical propagation delay, and TSSOP-16 package compatibility with high-density backplane routing.
Technical Context
The SN65LVCP23PWR 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 configurable 2:1 multiplexing, 1:2 demultiplexing, repeater, and signal splitting modes via SEL/EN control logic.
Each channel features LVPECL output drivers with 600–1000 mV differential output voltage, 50 Ω termination compatibility, and low added jitter (50 ps peak-to-peak at 1.3 Gbps). Input receivers tolerate ±100 mV differential thresholds with 25 mV hysteresis and operate over –40°C to 85°C.
Key Specifications

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 output); lower 1.0 Gbps max data rate; identical TSSOP-16 footprint | Suitable only when downstream receivers accept LVDS, not LVPECL; requires external level shifters for PECL interfaces | Select SN65LVCP22PW only if system uses LVDS-only signaling and cost reduction outweighs LVPECL compatibility loss. |
| MAX9119ESE+ | 2×2 LVDS crosspoint with integrated 50 Ω terminations; 800 Mbps max; SOIC-16 package only | Limited to LVDS endpoints; lacks CML/LVPECL input acceptance; no TSSOP option available | Choose MAX9119ESE+ only for space-constrained LVDS-only designs where SOIC-16 is acceptable and 800 Mbps suffices. |
Compared with SN65LVCP22PW and MAX9119ESE+, the SN65LVCP23PWR uniquely supports LVPECL outputs and multi-standard inputs in TSSOP-16, making it the sole option for mixed-signal optical infrastructure requiring 1.3 Gbps and sub-10 ps skew.

FAQ
What is the maximum data rate supported by the SN65LVCP23PWR?
The SN65LVCP23PWR supports up to 1.3 Gbps with PRBS 223–1 pattern testing and maintains <50 ps added peak-to-peak jitter at that rate. Its 650 MHz bandwidth and 750 ps typical propagation delay ensure reliable operation in Gigabit Ethernet and Fibre Channel applications. The SN65LVCP23PWR achieves this performance while maintaining LVPECL output compliance and multi-standard input acceptance.
Does the SN65LVCP23PWR require external termination resistors?
Yes, the SN65LVCP23PWR requires 50 Ω termination to VTT = VCC – 2 V on each LVPECL output pair (OUT0+/–, OUT1+/–), as specified in Figure 2 of the datasheet. Inputs are internally biased and do not require external termination. The SN65LVCP23PWR's receiver input stage operates over 0 V to 4 V common-mode range, eliminating need for AC-coupling or bias networks with LVDS or CML sources.
Can the SN65LVCP23PWR operate with a 2.5 V supply?
No, the SN65LVCP23PWR is specified only for 3.0 V to 3.6 V supply operation per its Recommended Operating Conditions table. Operation below 3.0 V violates absolute maximum ratings and risks failure to meet LVPECL output voltage specifications (VOH = VCC – 0.85 V, VOL = VCC – 1.65 V). The SN65LVCP23PWR must be powered from a regulated 3.3 V rail to guarantee 600–1000 mV differential output swing and 1.3 Gbps functionality.
How does the SN65LVCP23PWR handle input signal standards like LVDS and CML?
The SN65LVCP23PWR accepts LVDS, LVPECL, and CML inputs directly through its wide common-mode input range (0 V to 4 V) and ±100 mV differential threshold. No external level shifting or biasing is required - the internal receiver automatically adapts. The SN65LVCP23PWR processes these inputs and converts them to LVPECL outputs, enabling seamless inter-standard bridging in mixed-signal systems such as optical transponder modules.
What is the thermal performance of the SN65LVCP23PWR in TSSOP-16 package?
In TSSOP-16 (PW) package, the SN65LVCP23PWR has a junction-to-board thermal resistance (θJB) of 22.1 °C/W and dissipates up to 1074 mW at 25°C ambient. Derating is 10.7 mW/°C above 25°C, yielding 430 mW maximum at 85°C. This thermal profile supports continuous operation in industrial base stations and line cards without forced airflow, provided PCB copper area meets TI's recommended layout guidelines.
