TSM22-H50CQ33ST-27.000M-TR is listed in the Oscillators range at ChipApex. The manufacturer field lists Transko Electronics, Inc.. Its product description is XTAL OSC XO 27.0000MHZ HCMOS SMD. Review the specifications below when checking this part for your BOM.
The TSM22-H50CQ33ST-27.000M-TR is a 27 MHz crystal oscillator (XO) manufactured by Transko Electronics, Inc. It utilizes HCMOS output logic and operates on a 3.3V supply voltage. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 3.20mm x 2.50mm. This component is designed for surface mount installation and supports standard timing applications requiring precise frequency generation.
Verify the specific ordering suffix to ensure the correct frequency tolerance and load capacitance requirements are met for your application. Confirm that the HCMOS output voltage levels align with the receiving logic inputs. Check the datasheet for absolute maximum ratings regarding supply voltage and operating temperature range to prevent device damage during operation.
Select this component when a 27 MHz reference frequency is required with low profile surface mount constraints. Ensure the system design accommodates the 3.3V supply rail and provides necessary control signals for the enable pin. Consider thermal dissipation characteristics within the 4-SMD package footprint during PCB layout planning.
This part belongs to the TSM22 series of standard crystal oscillators from Transko Electronics. The series offers various frequency options within a standardized small outline package. It serves as a direct replacement for legacy through-hole or larger surface mount oscillators where space savings and automated assembly capabilities are prioritized.
Direct substitutes include other 27MHz HCMOS oscillators in 4-SMD packages such as those from SiTime or TXC, provided pinout and electrical specifications match exactly.
