PRODUCT OVERVIEW

What Is the LTC6995HS6-1#TRPBF?

LTC6995HS6-1#TRPBF is a silicon oscillator from Analog Devices with a programmable period range of 1.024ms to 9.54 hours (29.1µHz to 977Hz), specifically intended for long duration timing events. The LTC6995 is part of the TimerBlox® family of versatile silicon timing devices.

A single resistor, R_SET, programs the LTC6995's internal master oscillator frequency. The output clock period is determined by this master oscillator and an internal frequency divider, N_DIV, programmable to eight settings from 1 to 2²¹. When oscillating, the LTC6995 generates a 50% duty cycle square wave output.

A reset function is provided to stop the master oscillator and clear internal dividers. Removing reset initiates a full output clock cycle which is useful for programmable power-on reset and watchdog timer applications. The LTC6995 has two versions of reset functionality. The reset input is active high for the LTC6995-1 and active low for the LTC6995-2. The polarity of the output when reset is selectable for both versions. The LTC6995HS6-1#TRPBF is the H-Grade version in a low-profile 6-lead TSOT-23 package, rated for operation from –40°C to +125°C. The device is RoHS compliant, REACH unaffected, and in active production.

Programmable Period Range 1.024ms to 9.54 hours (29.1µHz to 977Hz) with maximum frequency error less than 1.5%.

Active-High Reset Input Timing reset by power-on or reset input, with programmable output polarity and 50% duty cycle square wave output.

Low Power Operation Single 2.25V to 5.5V supply with 55µA to 80µA supply current, 500µs start-up time, and 20mA CMOS output driver.

DEVICE HIGHLIGHTS

Key Features and Benefits of LTC6995HS6-1#TRPBF

Long Duration Timing Capability

Circuit Considerations for LTC6995HS6-1#TRPBF

Period & Frequency Programming

The LTC6995HS6-1#TRPBF offers flexible period and frequency programming:

Master Oscillator Frequency (R_SET Pin): A single resistor from SET to GND programs the internal master oscillator frequency. R_SET can range from 50kΩ to 800kΩ.
Output Period Formula: t_OUT = N_DIV × (R_SET / 50kΩ) × 1.024ms, where N_DIV = 1, 8, 64, 512, 4096, 32768, 262144, or 2097152.
Frequency Divider (DIV Pin): The DIV pin connects to an internal A/D converter that determines the DIVCODE value, setting one of eight N_DIV settings.
Output Polarity (POL Bit): Programmable output polarity during reset for both LTC6995-1 and LTC6995-2 versions.
Reset Function: The reset input is active high for the LTC6995-1. When reset is asserted, the master oscillator stops and internal dividers are cleared. Removing reset initiates a full output clock cycle.

PCB and System-Level Guidance

Silicon oscillator performance depends on layout and component selection:

Power Supply Bypass: Place a 0.1µF low-ESR ceramic bypass capacitor close to the V⁺ pin for stable operation.
R_SET Resistor Placement: Place R_SET as close as possible to the SET pin and connect it directly to the GND pin with short traces. The SET pin is a current summing node, and current into this pin directly modulates the operating frequency.
DIV Pin Configuration: Connect the DIV pin to V⁺, GND, or leave floating to set the desired N_DIV value. The DIV pin can also be driven by a resistor divider for additional divider settings.
Output Load: The CMOS output driver can source/sink 20mA. Ensure the output load does not exceed this rating.
Reset Input: For the LTC6995-1, the reset input is active high. Keep the reset signal trace short and away from switching nodes for noise immunity.
Verify the recommended PCB footprint from the official datasheet prior to production.
