Add To BomCDCM61004RHBT General Description
The CDCM61004 is a highly versatile, low-jitter frequency synthesizer capable of generating four 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 of LVCMOS input for a variety of wireline and data communication applications. The CDCM61004 features an onboard PLL that can be easily configured solely through control pins. The overall output random jitter performance is less than 1 ps, 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 CDCM61004 is available in a small, 32-pin, 5-mm × 5-mm VQFN package.
The CDCM61004 is a high-performance, low-phase noise, fully-integrated voltage-controlled oscillator (VCO) clock synthesizer with four 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 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 output 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 dividers are turned off.
The output frequency (fOUT) is proportional to the frequency of the input clock (fIN). The feedback divider, output divider, and VCO frequency set fOUT with respect to fIN.
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. CDCM61004 Block Diagram shows a high-level diagram of the CDCM61004.
The device operates in a 3.3-V supply environment and is characterized for operation from 40°C to 85°C.
