The CDCM61002 is a highly versatile, low-jitter frequency synthesizer that can generate two low-jitter clock outputs, selectable between low-voltage positive emitter coupled logic (LVPECL), low-voltage differential signaling (LVDS), or low-voltage complementary metal oxide semiconductor (LVCMOS) outputs, from a low-frequency crystal or LVCMOS input for a variety of wireline and data communication applications. The CDCM61002 features an onboard PLL that can be easily configured solely through control pins. The overall output random jitter performance is less than 1ps, RMS (from 10 kHz to 20 MHz), making this device a perfect choice for use in demanding applications such as SONET, Ethernet, Fibre Channel, and SAN. The CDCM61002 is available in a small, 32-pin,  5-mm × 5-mm QFN package.

The CDCM61002 is a high-performance, low phase noise, fully-integrated voltage-controlled oscillator (VCO) clock synthesizer with two universal output buffers that can be configured to be LVPECL, LVDS, or LVCMOS compatible. Each universal output can also be converted to two LVCMOS outputs. Additionally, an LVCMOS bypass output clock is available in an output configuration which can help with crystal loading in order to achieve an exact desired input frequency. It has one fully-integrated, low-noise, LC-based VCO that operates in the 1.75 GHz to 2.05 GHz range.

The phase-locked loop (PLL) synchronizes the VCO with respect to the input, which can either be a low-frequency crystal. The outputs share an output divider sourced from the VCO core. All device settings are managed through a control pin structure, which has two pins that control the prescaler and feedback divider, three pins that control the output divider, two pins that control the output type, and one pin that controls the output enable. Any time the PLL settings (including the input frequency, prescaler divider, or feedback divider) are altered, a reset must be issued through the Reset control pin (active low for device reset). The reset initiates a PLL recalibration process to ensure PLL lock. When the device is in reset, the outputs and dividered are turned off.

The output frequency (f_OUT) is proportional to the frequency of the input clock (f_IN). The feedback divider, output divider, and VCO frequency set f_OUT with respect to f_IN. For a configuration setting for common wireline and datacom applications, refer to. For other applications, useto calculate the exact crystal oscillator frequency required for the desired output.

The output divider can be chosen from 1, 2, 3, 4, 6, or 8 through the use of control pins. Feedback divider and prescaler divider combinations can be chosen from 25 and 3, 24 and 3, 20 and 4, or 15 and 5, respectively, also through the use of control pins.shows a high-level block diagram of the CDCM61002.

The device operates in a 3.3-V supply environment and is characterized for operation from -40°C to +85°C.
