Product details
Overview
SN65LVCP202RGER from Texas Instruments is a 2 × 2 nonblocking gigabit crosspoint switch with VML signaling, supporting up to 2.5-Gbps data rates, 30-ps deterministic jitter, and integrated 100-Ω differential termination. It features per-lane transmit preemphasis (0–9 dB), receive equalization (5/12 dB), and operates from a single 3.3-V supply for high-speed telecom/datacom routing applications.
For engineers reviewing the SN65LVCP202RGER datasheet, SN65LVCP202RGER pinout, SN65LVCP202RGER application, or SN65LVCP202RGER equivalent, key selection considerations include deterministic jitter performance at 2.5 Gbps, programmable preemphasis settings for FR4 trace compensation, VML output compatibility, flow-through pinout for PCB layout simplification, and thermal pad soldering requirements for junction temperature control.
Technical Context
The SN65LVCP202RGER implements a fully differential, nonblocking 2×2 crosspoint architecture with two independent 2:1 multiplexers - one per output channel - enabling any input (1A/1B or 2A/2B) to be routed to either output (1Y/1Z or 2Y/2Z). Each channel supports independent switching via LVTTL S1/S2 controls and data enable (xDE) for high-impedance state management.
It integrates on-die 100-Ω differential termination, self-biasing receiver inputs (VBB = 1.6 V), and dual-stage signal conditioning: a passive input equalizer (5 dB or 12 dB gain, 375 MHz–1.875 GHz) and selectable transmit preemphasis (0/3/6/9 dB) to compensate for frequency-dependent loss in backplane traces up to 40 inches of FR4.

Pinout & Package
SN65LVCP202RGER uses a 24-pin VQFN (RGE) package with 4-mm × 4-mm body, 1-mm max height, and exposed thermal pad requiring connection to ground plane via thermal vias. Pin 1 is located in Quadrant Q2 per tape-and-reel orientation.
| Pin/Terminal | Circuit Role | Design Meaning |

| VCC (pins 8,12,19) | Power supply | 3.3-V main supply; three pins reduce IR drop and improve PSRR |
| GND (pins 11,15,20) | Ground | Three dedicated ground pins plus exposed thermal pad - mandatory for thermal and EMI performance |
| VBB (pin 4) | Bias reference | Receiver input bias voltage (1.6 V); must be decoupled locally for optimal jitter performance |
Key Features

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 |
|---|---|---|---|
| SN65LVCP204RGER | 4×4 configuration, same 2.5-Gbps rating and VML I/O, but larger 32-pin RGR package and higher 420-mW power | Supports four independent channels instead of two - suitable for higher-port-count systems | Choose when expanding from 2×2 to 4×4 topology without changing signal integrity strategy |
| MAX4899AEETI+ | 2×2 analog crosspoint with 2-Gbps bandwidth, CMOS I/O, no integrated equalization or preemphasis | Designed for lower-speed, mixed-signal test equipment - lacks high-speed serial equalization features | Consider only for cost-sensitive, non-backplane applications where deterministic jitter <30 ps is not required |
Compared with SN65LVCP204RGER, the SN65LVCP202RGER offers lower power and smaller footprint for dual-lane routing; compared with MAX4899AEETI+, it delivers superior signal integrity for >2-Gbps serial links via built-in equalization and preemphasis - critical for telecom/datacom FR4 channel compliance.

FAQ
What is the maximum supported data rate for the SN65LVCP202RGER?
The SN65LVCP202RGER supports operation up to 2.5 Gbps per lane, verified under recommended conditions (VCC = 3.3 V, TA = –40°C to +85°C) with PRBS27–1 pattern testing. At this rate, deterministic jitter remains ≤30 ps peak-to-peak, and propagation delay is 500 ps typical - making SN65LVCP202RGER suitable for PCIe Gen1, SATA I, and 1000BASE-X applications.
Does the SN65LVCP202RGER require external termination resistors?
No, the SN65LVCP202RGER integrates 100-Ω differential termination on all outputs and 50-Ω termination to VBB on all inputs. This eliminates the need for external termination resistors, reducing PCB area and BOM count. However, VBB (pin 4) must be decoupled with a 0.1-µF capacitor to ground for optimal jitter performance in the SN65LVCP202RGER.
How is receive equalization configured on the SN65LVCP202RGER?
Receive equalization on the SN65LVCP202RGER is controlled by the EQ pin (pin 23): EQ = 1 selects 5-dB gain (optimized for ~25-inch FR4 traces), and EQ = 0 selects 12-dB gain (for ~43-inch FR4 traces). This setting applies to both receiver channels simultaneously and is latched on power-up - no dynamic reconfiguration is supported during operation of the SN65LVCP202RGER.
What is the purpose of the VBB pin on the SN65LVCP202RGER?
The VBB pin (pin 4) provides the internal bias voltage (1.6 V) for the differential receiver inputs. It enables AC-coupled CML signal interfacing without external bias networks. For best jitter performance, VBB must be decoupled to ground with a 0.1-µF ceramic capacitor placed within 2 mm of the SN65LVCP202RGER package - failure to do so degrades deterministic jitter by up to 15 ps.
Can the SN65LVCP202RGER outputs be placed in high-impedance state?
Yes, each output pair (1Y/1Z and 2Y/2Z) can be independently placed in high-impedance state using its dedicated active-low data enable pin (1DE on pin 24, 2DE on pin 7). When asserted, the corresponding outputs disconnect from the signal path - enabling power savings and bus sharing in multi-drop configurations. This feature is fully functional across the full operating temperature range of the SN65LVCP202RGER.
