Product details
Overview
SN65LVCP22PW from Texas Instruments is a 2×2 LVDS crosspoint switch IC supporting >1 Gbps per channel, with dual fully differential LVDS outputs, wide common-mode input range (0 V to 4 V), and configurable operation as repeater, 2:1 mux, or 1:2 splitter. It enables fault-tolerant serial bus switching in optical networking line cards.
For engineers reviewing the SN65LVCP22PW datasheet, SN65LVCP22PW pinout, SN65LVCP22PW application, or SN65LVCP22PW equivalent, key selection criteria include channel-to-channel skew (<10 ps typ), low added jitter (50 ps pk-pk max at 1 Gbps), LVDS/LVPECL/CML input compatibility, and TSSOP-16 package thermal performance (θJA = 10.7 mW/°C).
Technical Context
The SN65LVCP22PW implements a fully differential data path with independent enable (EN0/EN1) and select (SEL0/SEL1) control logic, enabling four distinct routing modes per function table. Its receiver accepts LVDS, LVPECL, and CML signals via wide common-mode range (0 V–4 V) and internal 300-kΩ termination.
Each output is a low-power LVDS driver delivering 270–475 mV differential voltage into 75 Ω, with propagation delay of 400–1000 ps and channel-to-channel skew ≤50 ps. Switching occurs in 1.7 ns (typ), with disable/enable times under 4 ns.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2×2 LVDS crosspoint switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum supported data rate for SN65LVCP22PW?
The SN65LVCP22PW supports up to 1 Gbps per channel, verified with PRBS 223−1 pattern testing at 1000 Mbps. This enables reliable operation in OC-192 (9.953 Gbps aggregate) and STM-64 systems using parallel LVDS lanes. Performance is specified across the full –40°C to +85°C temperature range with VCC = 3.0–3.6 V.
Does SN65LVCP22PW require external termination resistors?
No, the SN65LVCP22PW integrates 300-kΩ internal termination on all differential inputs (IN0±, IN1±), eliminating the need for external resistors when interfacing LVDS, LVPECL, or CML sources. External 75-Ω termination is required only at the receiver end of the output lines (OUT0±, OUT1±) to meet LVDS standard impedance matching.
Can SN65LVCP22PW operate with a 2.5-V supply?
No, the SN65LVCP22PW requires a minimum VCC of 3.0 V and is rated for 3.0–3.6 V operation only. Operation below 3.0 V is outside specification and may result in undefined switching behavior, increased jitter, or failure to meet LVDS output voltage compliance (270–475 mV). Use TI's SN65LVDS122 for 2.5-V compatible LVDS repeaters.
How does the enable functionality work on SN65LVCP22PW?
The SN65LVCP22PW features independent enable inputs EN0 and EN1: driving EN0 low places OUT0± in high-impedance state (2 ns typical disable time), while EN1 controls OUT1± identically. Both outputs remain active when EN0 and EN1 are high. This allows dynamic isolation of individual channels without affecting the other path's signal integrity.
Is SN65LVCP22PW pin-compatible with SN65LVCP22D?
Yes, SN65LVCP22PW and SN65LVCP22D share identical pin numbering, signal definitions, and function tables. The only difference is package type (TSSOP vs SOIC), so PCB layout must accommodate the smaller 5.0 mm × 4.4 mm TSSOP footprint and 0.65-mm pitch. Thermal and mechanical mounting requirements differ, but no schematic changes are needed.
