Product details
Overview
RC19016A100GN1#BB0 from Renesas Electronics is a 16-output ultra-high-performance PCIe Gen7 fanout buffer with LP-HCSL outputs, 100Ω output impedance, additive phase jitter of 2.4fs RMS (PCIe Gen7), and integrated Loss-of-Signal (LOS) monitoring. It supports Common Clock and Independent Reference architectures and operates from -40°C to +105°C at 3.3V ±10%, targeting high-speed server interconnects.
For engineers reviewing the RC19016A100GN1#BB0 datasheet, RC19016A100GN1#BB0 pinout, RC19016A100GN1#BB0 application, or RC19016A100GN1#BB0 equivalent, key selection criteria include PCIe Gen7 timing compliance, 16-channel LP-HCSL drive capability with 100Ω termination, Power Down Tolerant inputs, Flexible Startup Sequencing, and side-band interface support for daisy-chained enable control.
Technical Context
The RC19016A100GN1#BB0 implements a low-jitter clock distribution architecture optimized for PCIe Gen7 (32 GT/s) systems, featuring differential HCSL outputs with selectable 85Ω/100Ω impedance (A100 suffix confirms 100Ω). It accepts LVDS- or HCSL-level differential CLKIN and incorporates automatic clock parking upon input loss.
Its control subsystem integrates Power Down Tolerant (PDT) inputs, Flexible Startup Sequencing (FSS) logic, and a 4-wire Side-Band Interface (SBI) supporting high-speed serial output enable and device daisy-chaining - distinct from SMBus-only variants in the RC190xx family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output count | 16 LP-HCSL differential output pairs (32 pins total) |
| PCIe Gen7 additive phase jitter | 2.4fs RMS - meets PCIe Gen7 (32 GT/s) reference clock jitter budget |
| Output impedance | 100Ω - matched to standard LP-HCSL transmission lines; A100 suffix confirms this value |
| Operating temperature | -40°C to +105°C - qualified for industrial and server-grade thermal environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PCIe fanout buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT 9QXL2001B (DB2000QL) | 16-output, PCIe Gen5-rated (5.8fs Gen5 jitter); no SBI; pin-compatible but lacks LOSb and SBI_OUT pins | Valid for Gen5 systems only; cannot meet Gen7 jitter spec or leverage SBI daisy-chaining | Choose when Gen5 performance suffices and legacy DB2000QL footprint reuse is critical |
| Renesas RC19016A085GN1#BB0 | Same 16-output LP-HCSL buffer, identical package and pinout, but 85Ω output impedance (A085 suffix) | Requires different PCB trace impedance; not interchangeable without layout revision | Choose only if system design specifies 85Ω LP-HCSL termination |
Compared with IDT 9QXL2001B and RC19016A085GN1#BB0, RC19016A100GN1#BB0 uniquely delivers PCIe Gen7 timing compliance, integrated LOS monitoring, and SBI-enabled daisy-chain control - making it the only option for new Gen7 server and AI accelerator designs requiring full feature parity.

FAQ
What is the output impedance of RC19016A100GN1#BB0, and how is it configured?
The RC19016A100GN1#BB0 has a fixed 100Ω output impedance, confirmed by the "A100" suffix in its part number. Unlike variants with pin-selectable impedance, this version does not require external configuration - the 100Ω value is hardwired internally and matches standard LP-HCSL transmission line requirements for PCIe Gen7 applications.
Does RC19016A100GN1#BB0 support PCIe Gen7 timing specifications?
Yes, RC19016A100GN1#BB0 fully supports PCIe Gen7 with 2.4fs RMS additive phase jitter (12 kHz–20 MHz integration band), as specified in the official Renesas datasheet R31DS0016EU0128. This meets the stringent jitter budget required for reliable 32 GT/s link training and stable operation in next-generation servers and AI accelerators.
How does the Side-Band Interface (SBI) function on RC19016A100GN1#BB0?
The RC19016A100GN1#BB0 implements a 4-wire SBI (SBI_ENQ, SBI_IN, SBI_CLK, SBI_OUT) that enables daisy-chained serial output enable control - eliminating SMBus address conflicts and reducing PCB routing complexity. It operates independently of SMBus and supports high-speed toggling of output groups without software overhead.
What is the purpose of the LOSb pin on RC19016A100GN1#BB0?
The LOSb pin on RC19016A100GN1#BB0 is an open-drain output that asserts low when the device detects loss of valid signal on CLKIN. It requires an external pull-up resistor and feeds directly into system-level monitoring logic or watchdog circuits, enabling rapid fault detection and failover in redundant clock architectures.
Is RC19016A100GN1#BB0 pin-compatible with earlier Renesas or IDT fanout buffers?
RC19016A100GN1#BB0 uses the same 48-pin VFQFPN (GN1) package and pinout as the RC19016 series, but is not pin-compatible with IDT 9QXL2001B due to added SBI_OUT and LOSb pins on formerly NC locations. Direct replacement requires verification of signal mapping and firmware support for SBI functionality.
