Product details
Overview
SN65LVCP23D from Texas Instruments is a 2×2 LVPECL crosspoint switch IC supporting simultaneous high-speed data routing at up to 1.3 Gbps with 650 MHz bandwidth. It features dual LVPECL outputs, wide common-mode input range (0 V to 4 V), and accepts LVDS, LVPECL, and CML inputs - enabling signal-level translation in redundant serial bus architectures for optical networking line cards.
For engineers reviewing the SN65LVCP23D datasheet, SN65LVCP23D pinout, SN65LVCP23D application, or SN65LVCP23D equivalent, key selection criteria include channel-to-channel skew (<10 ps typ), fast switch time (1.7 ns typ), differential output voltage (600–1000 mV), jitter performance (50 ps pk-pk max at 1.3 Gbps), and SOIC-16 package compatibility with industrial temperature operation (–40°C to 85°C).
Technical Context
The SN65LVCP23D implements a fully differential data path with independent enable (EN0/EN1) and select (SEL0/SEL1) control logic, supporting configurable modes: 2:2 repeater, 2:1 multiplexer, 1:2 demultiplexer, and 1:2 splitter. Its receiver stage accommodates multiple signaling standards via a 0–4 V common-mode input range and ±100 mV differential threshold.
Each LVPECL output driver delivers 600–1000 mV differential swing into 50 Ω terminations referenced to VTT = VCC – 2 V, with propagation delay under 750 ps (typ), pulse skew ≤100 ps, and channel-to-channel skew ≤50 ps (max) in splitter mode - ensuring precise timing alignment across high-speed serial links.

Pinout & Package
SN65LVCP23D is housed in a 16-pin SOIC (D) package with 1.27 mm pitch, 10.3 mm × 6.5 mm body size, and exposed thermal pad not present. Pin assignment follows TI's standard D-package top-view layout with dual differential I/O pairs, dedicated enable/select controls, dual VCC and GND pins for supply decoupling, and no integrated termination resistors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN0+, IN0− | Differential input channel A | Accepts LVDS/LVPECL/CML signals; common-mode range 0–4 V enables direct interface to diverse sources |
| IN1+, IN1− | Differential input channel B | Independent second input path; supports redundancy or dual-source selection in protection-switching applications |
| OUT0+, OUT0− | LVPECL output channel A | Drives 50 Ω loads with VTT = VCC − 2 V; 600–1000 mV swing ensures robust noise margin at 1.3 Gbps |
| OUT1+, OUT1− | LVPECL output channel B | Matched delay and skew to OUT0; enables synchronous dual-path distribution in clock/data fanout |
| EN0, EN1 | Per-channel output enable | CMOS/TTL-compatible active-high control; allows dynamic channel gating without affecting signal integrity |
| SEL0, SEL1 | Routing configuration select | Defines 2:1 mux, 1:2 demux, repeater, or crosspoint mode; setup/hold times ≤1.1 ns support fast reconfiguration |
| VCC (pins 5, 8) | Power supply | Dual VCC pins reduce supply impedance; requires local 0.1 µF ceramic decoupling per pin |
| GND (pins 13, 16) | Ground reference | Dual ground pins minimize return-path inductance; critical for maintaining <50 ps channel skew |

|---|---|
Use Scenario: Dual-active link failover in enterprise switches where primary and backup SERDES paths must maintain bit-perfect synchronization during switchover. IC Role / Device Role / Timing Role: SN65LVCP23D acts as a low-skew, low-jitter 2×2 crosspoint switch that routes incoming serial data between working and protection lanes without retiming. Use Value: Channel-to-channel skew ≤50 ps (max) preserves inter-lane timing alignment, enabling hitless switchover compliant with IEEE 802.3ae and FC-PI-4 standards. |
Use Scenario: Protection switching in storage area network (SAN) directors where 1.0625–2.125 Gbps Fibre Channel links require sub-microsecond recovery after fiber cut detection. IC Role / Device Role / Timing Role: SN65LVCP23D serves as a 2:1 multiplexer with independent enable control, selecting between primary and backup FC transceivers while maintaining signal integrity. Use Value: 1.3 Gbps capability and 50 ps jitter meet FC-PI-4 Class III jitter compliance, eliminating need for additional CDR stages in protection path. |
| HDTV Video Routing | Optical Networking Line Cards/Switches |
Use Scenario: Distribution of uncompressed HD-SDI or 3G-SDI video streams across multiple display outputs or recording devices in broadcast infrastructure. IC Role / Device Role / Timing Role: SN65LVCP23D operates as a 1:2 signal splitter, replicating a single LVPECL video clock or data stream to two synchronized destinations. Use Value: Output skew <10 ps (typ) prevents visible timing artifacts (e.g., lip-sync drift or frame misalignment) across parallel video paths. |
Use Scenario: Signal routing between SONET/SDH framers and optical transponders on dense wavelength division multiplexing (DWDM) line cards requiring hot-swappable protection paths. IC Role / Device Role / Timing Role: SN65LVCP23D functions as a repeater with LVDS-to-LVPECL translation, conditioning and distributing OC-48/OC-192 clock/data to multiple downstream optics interfaces. Use Value: Wide input common-mode range (0–4 V) accepts legacy LVDS framers and modern LVPECL transponders without level-shifting components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed differential crosspoint switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVCP22D | 2×2 LVDS crosspoint (not LVPECL output); lower max data rate (1 Gbps); no CML input support | Suitable only where all connected devices use LVDS signaling and 1 Gbps suffices | Select SN65LVCP22D only if system uses LVDS end-to-end and does not require LVPECL drive strength or CML compatibility. |
| SN65LVDS101D | Gigabit repeater/translator (1:1 or 1:2); single-channel; LVDS input, LVPECL output; no crosspoint or mux functionality | Applicable for point-to-point signal boosting or level translation, not for multi-path routing or redundancy | Choose SN65LVDS101D when extending a single LVDS link to LVPECL without routing flexibility - not a functional substitute for SN65LVCP23D's 2×2 topology. |
Compared with SN65LVCP22D and SN65LVDS101D, the SN65LVCP23D uniquely combines 2×2 crosspoint switching, LVPECL output drive, multi-standard input acceptance, and sub-10 ps typical output skew - making it irreplaceable in protection-switching and redundant serial bus architectures requiring dynamic path reconfiguration.

FAQ
What signaling standards does the SN65LVCP23D support on its inputs?
The SN65LVCP23D accepts LVDS, LVPECL, and CML signals on both IN0 and IN1 differential input pairs. Its wide 0 V to 4 V common-mode input range and ±100 mV differential threshold enable direct interface without external biasing or level-shifting circuitry. This multi-standard compatibility is confirmed in the TI datasheet SLLS554E, Section 7.3 (Receiver DC Specifications) and Functional Description.
What is the maximum guaranteed data rate for the SN65LVCP23D?
The SN65LVCP23D is specified for operation up to 1.3 Gbps, validated using a 223–1 PRBS pattern at 650 MHz with 200 mV differential input voltage and 1.2 V common-mode voltage. This rating is documented in the "Features" section and Table 7 (Switching Characteristics) of the SLLS554E datasheet, with jitter and timing parameters guaranteed at this rate.
Does the SN65LVCP23D require external termination resistors?
Yes, the SN65LVCP23D requires external 50 Ω termination to VTT (VCC – 2 V) on each LVPECL output pair (OUT0+/− and OUT1+/−), as shown in Figure 2 of the SLLS554E datasheet. The device does not integrate termination resistors; proper external termination is essential to achieve specified 600–1000 mV differential output voltage and maintain signal integrity at 1.3 Gbps.
How is routing configuration controlled on the SN65LVCP23D?
Routing mode (2:2 repeater, 2:1 mux, 1:2 demux, or 2×2 crosspoint) is set by the logic states of SEL0 and SEL1 pins, as defined in the Circuit Function Table (Section 4 of SLLS554E). EN0 and EN1 provide independent per-output enable control. Setup and hold times for SEL inputs are specified at ≤1.1 ns, enabling dynamic reconfiguration within nanoseconds.
What package options are available for the SN65LVCP23D?
The SN65LVCP23D is exclusively offered in a 16-pin SOIC (D) package with 1.27 mm pitch, 10.3 mm × 6.5 mm body dimensions, and RoHS-compliant NiPdAu lead finish. It is supplied in tubes of 40 units.
