Introducción del producto:OTJRGLVTNF-148.50000 Presentación del producto

The OTJRGLVTNF-148.50000 from Taitien is a 148.5 MHz standard crystal oscillator providing LVDS (Low Voltage Differential Signaling) output from a 2.5V supply. The 148.5 MHz frequency is a standard clock rate for HD-SDI (SMPTE 292M) and 3G-SDI video interfaces, making this device ideal for broadcast and professional video applications. The LVDS output provides low EMI, low jitter, and high-speed clock distribution capability. The R in the part number denotes the ±50ppm stability grade, G indicates the 2.5V supply class, L denotes the temperature range, V denotes LVDS output, and NF indicates the Enable/Disable function. The 6-SMD no-lead package (5.0 x 3.2 x 1.35mm) is more compact than the 7x5mm variant, saving PCB space in dense video processing designs. The device is RoHS3 compliant.

Principio de funcionamiento:OTJRGLVTNF-148.50000 Principio de funcionamiento

The OTJRGLVTNF-148.50000 operates through three key subsystems:

1. Crystal Oscillator: An AT-cut quartz crystal operating in overtone mode provides the 148.5 MHz frequency reference. At this frequency, the crystal operates in its 3rd or higher overtone. The oscillator circuit includes mode selection components to ensure stable operation at the desired overtone. The crystal provides high Q and excellent phase noise characteristics.

2. LVDS Output Driver: The oscillator signal drives an LVDS output buffer that converts the single-ended oscillator signal to a differential current-mode output. LVDS drives a constant current (typically 3.5mA) through a pair of output pins, with the current direction determining the logic state. The differential signaling provides common-mode noise rejection, low EMI (due to the small voltage swing of ±350mV), and high-speed capability suitable for 148.5 MHz clock distribution.

3. Enable/Disable Control: The Enable/Disable function gates the LVDS output driver. When disabled, the output current source is turned off, and both output pins present high impedance. This enables clock gating for power management or clock source multiplexing in redundant timing architectures.
