Product details
Overview
LTC6905CS5-96#TRPBF from Analog Devices (formerly Linear Technology) is a factory-trimmed, fixed-frequency silicon oscillator IC delivering 96MHz, 48MHz, and 24MHz outputs via internal ÷1/÷2/÷4 divider selection. It operates from 2.7V to 5.5V, features ±0.5% typical frequency accuracy at 25°C, ±20ppm/°C temperature stability, and 0.5ns rise time into 5pF load - designed for high-reliability clocking in space-constrained industrial and automotive timing systems.
For engineers reviewing the LTC6905CS5-96#TRPBF datasheet, LTC6905CS5-96#TRPBF pinout, LTC6905CS5-96#TRPBF application, or LTC6905CS5-96#TRPBF equivalent, key selection criteria include its rail-to-rail CMOS output driving capability, synchronous OE control eliminating pulse slivers, fast 100µs start-up, and guaranteed performance across –40°C to 85°C (I-grade) with C-grade specified from 0°C to 70°C.
Technical Context
The LTC6905CS5-96#TRPBF integrates a master oscillator core with a three-state programmable divider (N = 1, 2, or 4), enabling three discrete output frequencies without external components. Its internal bias circuitry maintains VRES = 1V ±5%, ensuring stable frequency generation independent of supply variation within 2.7V–5.5V.
Output enable (OE) provides asynchronous disable and synchronous enable on the next rising edge, preventing glitches. The DIV pin detects high (V+), floating (mid-supply bias), or low (GND) states using dual 15µA current sources - requiring no external pull resistors but recommending 1nF bypassing when floating to suppress coupling.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiT8008BI-23-33E-96.000000 | MEMS-based; ±10ppm initial accuracy; 1.8V–3.3V supply only | Higher stability but narrower voltage range; no internal divider | Select for ultra-stable timing where supply is fixed at 3.3V and divider flexibility is not required |

FAQ
What are the exact output frequencies supported by the LTC6905CS5-96#TRPBF?
The LTC6905CS5-96#TRPBF delivers three factory-set frequencies: 96MHz when the DIV pin is tied to V+, 48MHz when DIV is left floating, and 24MHz when DIV is connected to GND. These correspond to internal division ratios of ÷1, ÷2, and ÷4 respectively - all derived from the same master oscillator frequency. No external components are needed to configure these outputs, and the part is fully specified for operation across its entire temperature and supply voltage range.
Does the LTC6905CS5-96#TRPBF require external load capacitors like quartz crystals?
No, the LTC6905CS5-96#TRPBF does not require external load capacitors. As a fully integrated silicon oscillator IC, it contains all necessary timing elements internally and is factory-trimmed for accuracy. Unlike quartz-based solutions, it operates as a self-contained clock source with only V+, GND, OE, DIV, and OUT connections needed - eliminating matching capacitors, PCB layout sensitivity, and aging-related drift associated with crystal-based designs.
How does the OE (Output Enable) pin behave during power-up and state transitions?
The OE pin on the LTC6905CS5-96#TRPBF provides asynchronous disable and synchronous enable: pulling OE low immediately disables the output, while pulling OE high enables the output on the next rising edge of the internal clock - preventing pulse slivers or runt pulses. During power-up, if OE is left unconnected (floating), it defaults to enabled due to internal weak pull-up behavior. For reliable startup control, OE should be driven actively or pulled to V+ via a resistor to ensure deterministic initialization.
What is the maximum capacitive load the LTC6905CS5-96#TRPBF can drive at 96MHz?
At 96MHz output (÷1 mode), the LTC6905CS5-96#TRPBF can reliably drive up to approximately 12pF total capacitive load while maintaining specified rise/fall times and jitter performance. This is derived from the 27Ω typical output resistance (at 3V supply) and the 20% period limit rule: maximum CLOAD ≤ 45454/(ROUT × fOSC) = 45454/(27 × 96) ≈ 17.5pF - with margin applied per design guidelines. For heavier loads, a buffer stage is recommended to preserve signal integrity.
Is the LTC6905CS5-96#TRPBF qualified for automotive applications?
The LTC6905CS5-96#TRPBF is rated for commercial temperature range (0°C to 70°C) and is not AEC-Q200 qualified. However, the pin-compatible LTC6905IS5-96#TRPBF (–40°C to 85°C) and LTC6905HS5-96#TRPBF (–40°C to 125°C) are available for automotive and industrial applications. All variants share identical electrical specifications and pinout - only temperature grade and screening differ. For automotive use, specify the I- or H-grade version instead of the C-grade LTC6905CS5-96#TRPBF.
