Texas Instruments SN65LVCP22PWR

Overview

SN65LVCP22PWR from Texas Instruments is a 2×2 LVDS crosspoint switch IC supporting >1 Gbps per channel, featuring dual fully differential LVDS drivers and wide common-mode (0 V to 4 V) receivers compatible with LVDS, LVPECL, and CML inputs. It delivers 10 ps typical channel-to-channel output skew, 50 ps peak-to-peak jitter (PRBS 2²³−1), and operates at 3.3 V supply across −40°C to 85°C - deployed in optical networking line cards for protection switching and redundant serial backplane routing.

For engineers reviewing the SN65LVCP22PWR datasheet, SN65LVCP22PWR pinout, SN65LVCP22PWR application, or SN65LVCP22PWR equivalent, key selection criteria include its 16-pin TSSOP package, configurable 2:1 mux / 1:2 splitter / repeater modes, sub-2 ns switch time, and support for fault-tolerant gigabit serial bus architectures requiring precise timing alignment and low-power differential signaling.

Technical Context

The SN65LVCP22PWR implements a fully differential signal path with independent enable (EN0/EN1) and select (SEL0/SEL1) control logic, enabling four distinct functional configurations via a 2-bit control bus. Its receiver stage accepts differential input voltages from ±100 mV to ±1000 mV with hysteresis of 25 mV, while outputs deliver 285–440 mV differential voltage into 75 Ω loads at 3.3 V.

Thermal design is constrained by a junction-to-board thermal resistance (θ_JB) of 18.4 °C/W in the TSSOP (PW) package, with maximum power dissipation rated at 430 mW at 85°C ambient. Propagation delay is tightly controlled at 400–1000 ps (low-to-high/high-to-low), and pulse skew remains ≤100 ps under load.

FAQ

What is the maximum supported data rate for SN65LVCP22PWR?

The SN65LVCP22PWR supports up to 1 Gbps per channel, verified with PRBS 2²³−1 pattern testing at 3.3 V supply and 25°C ambient. At this rate, it achieves 50 ps typical peak-to-peak jitter and meets TIA/EIA-644-A LVDS specifications for differential output voltage and common-mode noise rejection. Operation beyond 1 Gbps is not characterized or guaranteed.

Can SN65LVCP22PWR accept LVPECL inputs directly?

Yes, SN65LVCP22PWR accepts LVPECL inputs directly due to its wide 0 V to 4 V common-mode input voltage range and differential receiver threshold of ±100 mV. No external level-shifting circuitry is required - the device internally conditions LVPECL signals for LVDS-compatible output, enabling seamless integration in mixed-signaling environments like base station radio units.

What are the power supply requirements for SN65LVCP22PWR?

SN65LVCP22PWR requires a single 3.3 V supply (range: 3.0 V to 3.6 V) applied to pin 5 (V_CC). Total supply current is 60–87 mA at 1 Gbps with both outputs enabled, and drops to 25–35 mA in 3-state mode. A minimum 100 nF ceramic decoupling capacitor must be placed within 3 mm of V_CC and GND (pin 13) to maintain jitter performance.

How does the function control logic work on SN65LVCP22PWR?

SN65LVCP22PWR uses two digital inputs - SEL0 (pin 2) and SEL1 (pin 1) - to configure four operating modes per its function table: SEL0=0/SEL1=0 → 1:2 splitter (IN0 routed to both outputs); SEL0=0/SEL1=1 → repeater (IN0→OUT0, IN1→OUT1); SEL0=1/SEL1=0 → switch (IN1→OUT0, IN0→OUT1); SEL0=1/SEL1=1 → 1:2 splitter (IN1 routed to both outputs). EN0/EN1 independently disable each output.

Is SN65LVCP22PWR pin-compatible with SN65LVCP22D?

Yes, SN65LVCP22PWR and SN65LVCP22D share identical pin numbering, signal definitions, and control logic - differing only in package type (TSSOP-16 vs. SOIC-16). The TSSOP version offers 35% smaller footprint and improved thermal resistance for high-density layouts, while the SOIC version provides greater mechanical robustness and easier hand-soldering.
