Product details
Overview
LTC6905HS5-96#TRMPBF from Analog Devices (formerly Linear Technology) is a precision fixed-frequency silicon oscillator IC with factory-programmed 96MHz master clock, offering three output frequencies (96MHz/48MHz/24MHz) via internal ÷1/÷2/÷4 divider, ±0.5% typical frequency accuracy at 25°C, ±20ppm/°C temperature stability, and rail-to-rail CMOS output driving 600Ω loads. It serves as a drop-in replacement for quartz crystals in high-vibration industrial timing applications.
For engineers reviewing the LTC6905HS5-96#TRMPBF datasheet, LTC6905HS5-96#TRMPBF pinout, LTC6905HS5-96#TRMPBF application, or LTC6905HS5-96#TRMPBF equivalent, key selection criteria include its -40°C to 125°C extended temperature grade, fast 100µs start-up time, OE-controlled synchronous enable/disable, and low-jitter (<0.8% typical) square-wave generation under single 2.7V–5.5V supply.
Technical Context
The LTC6905HS5-96#TRMPBF integrates a master oscillator core with a three-state programmable divider (N = 1, 2, or 4), enabling three discrete output frequencies from one device. Its internal bias circuit maintains VRES = 1V ±5%, ensuring stable oscillation independent of supply voltage variation within 2.7V–5.5V.
Output enable (OE) operates asynchronously for disable but synchronously for enable-triggering on the next rising edge of the internal clock to eliminate pulse slivers. The DIV pin uses dual 15µA current sources to detect high/floating/low states, requiring no external pull resistors but recommending 1nF bypass when floating.

FAQ
What is the maximum operating temperature specification for the LTC6905HS5-96#TRMPBF?
The LTC6905HS5-96#TRMPBF is rated for continuous operation from –40°C to +125°C, with full electrical specifications guaranteed across this extended temperature range. This H-grade qualification makes it suitable for under-hood automotive, industrial motor drives, and avionics applications where ambient temperatures exceed standard commercial or industrial grades. The device's ±20ppm/°C frequency stability ensures minimal drift even at maximum junction temperature.
Does the LTC6905HS5-96#TRMPBF require external passive components to operate?
No, the LTC6905HS5-96#TRMPBF requires no external passive components to set or stabilize its frequency. It is factory-trimmed to 96MHz master frequency and contains all necessary oscillator circuitry on-die. Only a 0.1µF ceramic bypass capacitor between V+ and GND is recommended for power supply noise suppression - no crystal, load capacitors, or timing resistors are needed. This eliminates component count, board area, and calibration steps.
How does the OE (Output Enable) pin function on the LTC6905HS5-96#TRMPBF?
The OE pin on the LTC6905HS5-96#TRMPBF controls output state: pulling OE low disables the output driver asynchronously (immediate shutdown), while pulling OE high enables it synchronously on the next rising edge of the internal clock - preventing runt pulses or glitches. This behavior is intrinsic to the LTC6905HS5-96#TRMPBF design and ensures clean clock gating for power management in systems like automotive ECUs and portable medical devices.
What are the three output frequencies supported by the LTC6905HS5-96#TRMPBF and how are they selected?
The LTC6905HS5-96#TRMPBF provides 96MHz (÷1), 48MHz (÷2), and 24MHz (÷4) outputs selected via the DIV pin: tie DIV to V+ for 96MHz, leave floating for 48MHz, or tie to GND for 24MHz. This three-state selection is implemented using internal 15µA current sources and requires no external logic. All three frequencies retain the same ±0.5% accuracy and <0.8% jitter characteristics of the LTC6905HS5-96#TRMPBF.
Can the LTC6905HS5-96#TRMPBF drive a 50Ω transmission line directly?
The LTC6905HS5-96#TRMPBF CMOS output is specified to drive a 600Ω resistive load or 5pF capacitive load. Driving a 50Ω line directly would cause excessive current draw and waveform distortion. For 50Ω termination, a series resistor (e.g., 450Ω) should be added between OUT and the line to match impedance and limit current - as demonstrated in the "Driving a 50Ω Cable" application circuit in the official datasheet for the LTC6905HS5-96#TRMPBF.
