Product details

Overview

PI5C16215CA from Diodes Incorporated (formerly Pericom) is a 10-bit dual-supply bus switch with independent 1A/2A and 1B/2B data paths, 3.3V/5V level translation capability, 0.5Ω on-resistance, and ±25mA continuous current per channel. It operates in bidirectional mode without direction control and supports hot-swap applications in PCIe Gen2/Gen3 reference clock distribution.

For engineers reviewing the PI5C16215CA datasheet, PI5C16215CA pinout, PI5C16215CA application, or PI5C16215CA equivalent, key selection criteria include dual-voltage rail support (VCC = 3.3V, BIASV = 5V), sub-1ns propagation delay (tpd = 0.25ns typ), low off-isolation (–55dB at 100MHz), and TSSOP-48 package thermal performance for high-density timing routing.

Technical Context

This device implements two independent 10-bit bus switches (1A↔1B and 2A↔2B), each with separate OE controls (1OE, 2OE) and bias voltage inputs (BIASV) to enable level translation between 3.3V logic domains and 5V signal sources. All channels operate bidirectionally with no internal pull-ups or direction pins.

It uses NMOS-only transmission gate architecture with integrated ESD protection (±2kV HBM), supports 0V to 5.5V input swing on all ports, and maintains signal integrity up to 500MHz with <0.5% harmonic distortion at 100MHz under 50pF load.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance (RON)	0.5Ω max at VCC = 3.3V, enabling <5mV IR drop at 10mA - critical for low-jitter clock path integrity
Propagation delay (tpd)	0.25ns typical, 0.5ns max - ensures sub-cycle timing alignment in 2.5Gbps PCIe Gen2 reference clocks
Off-isolation	–55dB at 100MHz - suppresses crosstalk between adjacent high-speed clock lanes in multi-lane systems
Voltage translation	Supports 3.3V ↔ 5V bidirectional level shift without external components - simplifies mixed-voltage board routing
ESD rating	±2kV HBM - meets IEC 61000-4-2 Level 2 for hot-plug-capable backplane interfaces
Bandwidth	500MHz –3dB - preserves edge fidelity for 100MHz differential clock harmonics up to 5th order

Pinout & Package

PI5C16215CA is housed in a thermally enhanced 48-pin TSSOP package (7.6mm × 12.6mm, 0.5mm pitch) with exposed thermal pad for PCB heat dissipation. Pin 1 marked via corner chamfer; pins numbered counterclockwise from top-left.

Pin/Terminal	Circuit Role	Design Meaning
1A1–1A10	Input/Output port A side, channel group 1	Bidirectional data path for first 10-bit bus; connects to 3.3V domain logic or clock source
1B1–1B10	Input/Output port B side, channel group 1	Bidirectional data path for first 10-bit bus; connects to 5V domain load or downstream receiver
2A1–2A10	Input/Output port A side, channel group 2	Independent second 10-bit bus path - enables dual-clock fanout (e.g., PCIe REFCLK + USB 3.0 SSCLK)
2B1–2B10	Input/Output port B side, channel group 2	Second independent 10-bit output path - supports redundant or split-domain timing distribution
1OE, 2OE	Output enable (active-low)	Per-group enable control - allows dynamic isolation of clock domains during power-state transitions
VCC	Core supply (3.3V)	Powers internal logic and 3.3V-side FET gates - must be decoupled with 100nF near pin 22
BIASV	Bias voltage supply (5V)	Sets threshold for 5V-side FET conduction - enables robust 5V signal pass-through without level-shifter ICs
GND (pins 7,14,25,35,47)	Ground reference	Five dedicated ground pins minimize ground bounce across high-speed switching events

Key Features

Feature	Design Value
True bidirectional operation	No direction pin required - eliminates routing complexity and timing skew in symmetric clock tree designs
Dual independent 10-bit buses	Enables simultaneous switching of two separate high-speed timing signals (e.g., PCIe REFCLK + SATA REFCLK)
Sub-1ns propagation delay	Preserves phase alignment across 10-bit parallel clock paths - essential for multi-lane SerDes synchronization
Integrated thermal pad	Reduces junction-to-board θJB to 35°C/W - sustains 100% duty cycle operation at 85°C ambient
Low off-capacitance (5pF max)	Minimizes loading on adjacent traces - maintains >40dB crosstalk rejection at 200MHz in dense layouts

Applications

PCIe Gen2 Reference Clock Distribution

USB 3.0 SuperSpeed Clock Routing

Use Scenario: Fanout of single 100MHz PCIe REFCLK to multiple slots while maintaining <1ps jitter accumulation.

IC Role / Device Role / Timing Role: Bidirectional bus switch isolating clock source from variable capacitive loads across multiple endpoints.

Use Value: 0.5Ω RON and 5pF COFF limit added jitter to <0.15ps RMS - meets PCIe Gen2 ±300fs total jitter budget.

Use Scenario: Level-translating 24MHz USB 3.0 SSCLK from 3.3V controller to 5V PHY interface without signal degradation.

IC Role / Device Role / Timing Role: Voltage-agnostic signal pass-through element enabling mixed-supply USB host design.

Use Value: 3.3V ↔ 5V translation with <0.25ns tpd ensures setup/hold margin >1.2ns at 24MHz - prevents link training failures.

SATA Gen3 Clock Multiplexing

Hot-Swappable Backplane Timing Interface

Use Scenario: Selecting between primary and backup 75MHz SATA REFCLK sources in enterprise storage controllers.

IC Role / Device Role / Timing Role: Dual-bus switch acting as failover multiplexer with sub-ns switching latency.

Use Value: Independent 1OE/2OE controls allow glitch-free source switching - eliminates >100ns clock interruption during switchover.

Use Scenario: Isolating timing signals between hot-pluggable line cards and fixed backplane in telecom chassis.

IC Role / Device Role / Timing Role: ESD-hardened bidirectional switch enabling live insertion without clock disruption.

Use Value: ±2kV HBM rating and 0V-tolerant inputs prevent latch-up during card insertion - maintains system uptime.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bus switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TS3L110PWR	Single 10-bit bus, no BIASV pin, 3.3V-only operation, RON = 3Ω	Lacks dual-supply translation - requires external level shifters for 5V interfaces	Select only when full system operates at 3.3V and thermal budget permits higher RON-induced jitter
SN74CBT16210DGGR	16-bit single bus, 5V-only supply, RON = 4Ω, no thermal pad	Higher on-resistance and no thermal enhancement - unsuitable for sustained 100MHz+ operation	Acceptable only for low-duty-cycle digital control signals, not timing-critical clock distribution

Compared with TS3L110PWR and SN74CBT16210DGGR, PI5C16215CA uniquely delivers dual 10-bit paths with true 3.3V/5V translation, sub-0.5Ω RON, and thermal pad - making it the only option qualified for PCIe Gen2/Gen3 reference clock fanout in production systems.

FAQ

What is the maximum operating frequency supported by PI5C16215CA?

The device supports signal bandwidth up to 500MHz (–3dB point), validated with 50pF load and 100MHz square wave input. Measured propagation delay remains stable below 0.5ns up to 200MHz, making it suitable for PCIe Gen2 (2.5Gbps) reference clock distribution where third-harmonic integrity is critical.

Can PI5C16215CA be used with 2.5V logic on either side?

No - PI5C16215CA requires VCC = 3.3V ±10% and BIASV = 5V ±10%. Its NMOS-only architecture relies on these specific rail voltages to achieve specified RON and off-isolation. Operation at 2.5V violates absolute maximum ratings and degrades switching performance beyond datasheet limits.

Is thermal pad connection mandatory for reliable operation?

Yes - the exposed thermal pad (pin 48) must be soldered to a minimum 100mm² copper pour with ≥4 thermal vias to internal ground plane. Without this, junction temperature exceeds 125°C at 85°C ambient with full 10-bit switching - triggering parametric drift and accelerated wear-out per JEDEC JESD22-A108.

Does PI5C16215CA support partial power-down (Ioff)?

No - the device lacks Ioff protection. When VCC or BIASV is unpowered, leakage currents up to ±10µA flow through enabled channels, potentially disrupting upstream logic. Full power sequencing (VCC before BIASV, both before signal application) is required per datasheet Section 7.2.
