Skyworks Solutions Inc. SI5334C-B05192-GMR

Overview

SI5334C-B05192-GMR from Skyworks Solutions is a pin-controlled, quad-output any-frequency clock generator with four independently configurable differential clock outputs. It synthesizes frequencies from 0.16 MHz to 710 MHz per output using MultiSynth fractional-N synthesis, delivers 0.7 ps RMS typical phase jitter, supports LVPECL/LVDS/HCSL/CMOS/SSTL/HSTL formats, and operates from 1.8/2.5/3.3 V core and output supplies - deployed in PCIe 3.0 timing, FPGA clocking, and broadcast video systems.

For engineers reviewing the SI5334C-B05192-GMR datasheet, SI5334C-B05192-GMR pinout, SI5334C-B05192-GMR application, or SI5334C-B05192-GMR equivalent, key selection considerations include its 4× independent output frequency/phase/format configurability, zero-ppm accuracy across all outputs, 24-pin 4×4 mm QFN package, loss-of-signal detection, and pin-based frequency/phase adjustment without I²C interface.

Technical Context

The SI5334C-B05192-GMR integrates a fully on-chip fractional-N PLL (phase detector, charge pump, loop filter, VCO, R/N dividers) followed by four independent MultiSynth output synthesis stages, each with M/P dividers enabling non-integer frequency generation up to 710 MHz. Input flexibility includes crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), or differential (5–710 MHz) references.

Each of the four differential outputs features independent voltage control (1.5/1.8/2.5/3.3 V), format selection (LVPECL/LVDS/HCSL/CMOS/SSTL/HSTL), and programmable initial phase offset (±45 ns) with 20 ps step resolution. The device supports optional zero-delay mode via external feedback and PCI Express–compliant spread spectrum on 100 MHz outputs.

FAQ

What input reference sources does the SI5334C-B05192-GMR support?

The SI5334C-B05192-GMR accepts an external crystal (8–30 MHz), single-ended CMOS clock (5–200 MHz on IN3/IN4), SSTL/HSTL clock (5–350 MHz), or differential clock (5–710 MHz on IN1/IN2 or IN5/IN6). All inputs are internally terminated and compatible with standard logic families without external biasing.

Does the SI5334C-B05192-GMR require I²C programming to operate?

No. The SI5334C-B05192-GMR is factory-programmed with a predefined configuration stored in one-time-programmable (OTP) memory. Upon power-up, it begins generating clocks immediately without host intervention - pin control (e.g., OEB, LOSLOL, frequency/phase adjust pins) suffices for runtime operation.

Can all four outputs of the SI5334C-B05192-GMR run at different frequencies and signal formats simultaneously?

Yes. Each of the four differential outputs (CLK0A/B through CLK3A/B) is independently configurable for frequency (0.16–710 MHz), format (LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL), and output supply voltage (1.5/1.8/2.5/3.3 V), enabling true heterogeneous clock domain generation from a single device.

What is the maximum frequency supported by the SI5334C-B05192-GMR on LVPECL outputs?

The SI5334C-B05192-GMR supports LVPECL outputs up to 710 MHz, but only under specific conditions: the MultiSynth output frequency must remain between 5 MHz and Fvco/8, and only two unique frequencies above Fvco/8 (e.g., Fvco/4 and Fvco/6) may be generated simultaneously.

How does the SI5334C-B05192-GMR handle loss of input clock or PLL lock?

The SI5334C-B05192-GMR asserts the open-drain LOSLOL pin within 5 µs of input clock loss or PLL unlock. This alarm signal can trigger system-level failover or diagnostic routines. Outputs continue running at last valid frequency until reset or power cycle - no automatic holdover mode is implemented.
