Product details

Overview

SN65LVCP23PWRG4 from Texas Instruments is a 2×2 LVPECL crosspoint switch IC designed for high-speed serial bus redundancy and signal routing in optical networking, wireless infrastructure, and datacom systems. It supports 1.3 Gbps data rates, delivers <10 ps typical channel-to-channel output skew, accepts LVDS/LVPECL/CML inputs, and provides dual LVPECL outputs with 600–1000 mV differential swing at 3.3 V supply.

For engineers reviewing the SN65LVCP23PWRG4 datasheet, SN65LVCP23PWRG4 pinout, SN65LVCP23PWRG4 application, or SN65LVCP23PWRG4 equivalent, key selection criteria include its 1.7 ns typical switch time, 50 ps max added peak-to-peak jitter (PRBS 2²³−1), −40°C to 85°C operating range, TSSOP-16 package compatibility, and support for 2:2 repeater, 1:2 splitter, 2:1 mux, and full crosspoint configurations.

Technical Context

The SN65LVCP23PWRG4 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 feature separate enable (EN0/EN1) and select (SEL0/SEL1) controls, supporting asynchronous switching and configurable routing modes without shared control logic.

Each channel integrates a high-impedance LVPECL driver with 50 Ω termination capability (V_TT = V_CC − 2 V), low pulse-width distortion (<100 ps skew), and fast propagation delay (750 ps typ). Input receivers tolerate ±100 mV differential thresholds with 25 mV hysteresis, ensuring robust operation under signal integrity degradation.

Key Specifications

IN1+, IN1−	Differential input channel 1	Independent of IN0; supports redundant source selection or dual-data-path routing
OUT0+, OUT0−	LVPECL output channel 0	Drives 50 Ω terminated lines with 600–1000 mV differential swing; requires V_TT = V_CC − 2 V
OUT1+, OUT1−	LVPECL output channel 1	Matched delay and skew to OUT0; enables synchronous dual-output distribution
SEL0, SEL1	Routing control inputs	Configure crosspoint state (00=pass-thru, 01=swap, 10=IN0→both, 11=IN1→both); CMOS/TTL compatible
EN0, EN1	Channel enable inputs	Asynchronous per-channel disable; forces outputs to high-impedance state with 2.5 ns enable/disable times
VCC, GND	Power and ground	Single 3.3 V supply; two VCC pins (pins 5 & 8) and two GND pins (pins 13 & 16) reduce supply noise coupling

Key Features

Feature	Design Value
Configurable topology	Supports 2:2 repeater, 1:2 splitter, 2:1 mux, and full 2×2 crosspoint - reduces BOM count in modular line cards

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed crosspoint switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN65LVCP22PW	2×2 LVDS crosspoint (not LVPECL); lower 600 Mbps max rate; 1.2 V common-mode only	Suitable for LVDS-only systems (e.g., camera sensor interfaces), not mixed-signal or LVPECL-driven backplanes	Select SN65LVCP22PW only when all sources/sinks are LVDS and data rates ≤600 Mbps.
MAX9119ESE+	2×2 LVDS crosspoint with integrated 100 Ω termination; no LVPECL output drive; 800 Mbps max	Targeted at compact LVDS fanout in test equipment; lacks level translation and high-speed repeater mode	Choose MAX9119ESE+ for space-constrained LVDS distribution where external termination is undesirable.

Compared with SN65LVCP22PW and MAX9119ESE+, the SN65LVCP23PWRG4 uniquely supports LVPECL output drive, 1.3 Gbps operation, and LVDS/LVPECL/CML input interoperability-making it the only option for telecom-grade redundant serial bus switching requiring sub-10 ps skew and multi-standard compatibility.

FAQ

What is the maximum supported data rate for SN65LVCP23PWRG4?

The SN65LVCP23PWRG4 is characterized for operation up to 1.3 Gbps with PRBS 2²³−1 pattern and specified jitter performance. While functional at higher rates (up to 2 Gbps per switching characteristics table), 1.3 Gbps is the guaranteed data rate for full parameter compliance including skew, jitter, and signal integrity metrics.

Does SN65LVCP23PWRG4 require external termination resistors?

Yes. The SN65LVCP23PWRG4 LVPECL outputs require 50 Ω termination to V_TT, where V_TT = V_CC − 2 V (typically 1.3 V at 3.3 V supply). No internal termination is provided; external resistors must be placed at the load end of the transmission line to prevent reflections.

Can SN65LVCP23PWRG4 accept single-ended inputs?

No. SN65LVCP23PWRG4 inputs are strictly differential (IN0+/IN0−, IN1+/IN1−) and require balanced signaling. Single-ended signals must be converted to differential using an external transformer or dedicated converter IC before connection to SN65LVCP23PWRG4.

What is the function of the EN0 and EN1 pins on SN65LVCP23PWRG4?

EN0 and EN1 are independent channel enable inputs. When low, they force the corresponding output pair (OUT0 or OUT1) into high-impedance state. This allows per-channel shutdown for power management or isolation during protection switching, with 2.5 ns typical enable/disable timing.

Is SN65LVCP23PWRG4 pin-compatible with SN65LVCP23PW?

Yes. SN65LVCP23PWRG4 is a tape-and-reel variant of the SN65LVCP23PW, sharing identical TSSOP-16 pinout, electrical specifications, thermal characteristics, and marking (LVCP23). The "G4" suffix denotes TI's green packaging standard (halogen-free, RoHS-compliant), with no functional or mechanical differences.
