FREQUENCY TRANSLATION PLL Product Data Sheet FUNCTIONAL DESCRIPTION N Divider and Outputs The M2004-01/-11 is a PLL (Phase Locked Loop) based clock generator that generates output clocks synchronized to one of two selectable input reference clocks. An internal high “Q” SAW delay line provides a low jitter clock signal. The device can be pin-configured for feedback divider and output divider values. These divider values can also be set through serial programming. Output is LVPECL compatible. External loop filter component values set the PLL bandwidth to optimize jitter attenuation characteristics. The M2004-11 adds Hitless Switching with Phase Build-out (HS/PBO) to provide SONET/SDH MTIE and TDEV compliance during a reference clock reselection using the internal mux or when using an external mux. The M2004-01/-11 is ideal for clock jitter attenuation and frequency translation in 2.5 or 10 Gb optical network line card applications. Input Reference Clocks An internal input MUX is provided for input reference clock selection. One input reference clock is selected from between two single-ended LVCMOS / LVTTL clock inputs. The maximum input frequency is 175MHz. PLL Operation The M2004-01/-11 is a complete clock PLL. It uses a phase detector and configurable dividers to synchronize the output of the VCSO with the selected reference clock. The “M Divider” divides the VCSO output frequency, feeding the result into the phase detector. The selected input reference clock is fed into the other input of the phase detector. The phase detector compares its two inputs. It then causes the VCSO to increase or decrease in speed as needed to phase- and frequencylock the VCSO to the reference input. The value of M directly affects closed loop bandwidth. The M2004-01/-11 provides one differential LVPECL output pair: FOUT, nFOUT. By using the N divider, the output frequency can be the VCSO center frequency (Fvcso) or 1/2, 1/4, or 1/8 Fvcso. The N1 and N0 pins select the value for the N divider. See Table 5, Pin Selection of N Divider Using N1:0 Pins, on pg. 3. When the N divider is included, the complete relationship for the output frequency (Fout) is defined as: M Fvcso = Fref_clk × -------Fout = ------------------N N Configuration of M and N Dividers The M and N dividers can be set by pin configuration or serial programming. The divider configuration of the M2004-01/-11 is reset when the input pin MR is set HIGH. MR is set LOW for divider configuration to be operational. See Table 7, Pin Configuration & Serial Programming Functions, on pg. 5. Pin Configuration M and N Dividers The M2004-01/-11 can be pin-configured with the input pins M0 - M5, N0, and N1. Pin configuration of dividers occurs when nP_LOAD is LOW. The data on pins M5:0 and pins N1:0 is passed transparently (directly) to the M and N dividers. On the LOW-to-HIGH (rising edge) transition of the nP_LOAD input, the data is latched. With nP_LOAD set HIGH, the pin-configured values remain loaded in the M and N dividers; the dividers are unaffected by any change to the M5:0 or N1:0 inputs. As a result, the M5:0 and N1:0 pins can be used to set the power-up default values for M and N. (The dividers are also unaffected by any S_DATA serial input as long as there is no rising edge transition of S_LOAD.) See Table 7, Pin Configuration & Serial Programming Functions, on pg. 5. See also Figure 8, Times for M5:0 and N1:0, on pg. 9. The M Divider The relationship between the VCSO center frequency (Fvcso), the M divider, and the input reference frequency (Fref_clk) is: Fvcso = Fref_clk × M The product of M and the input frequency must be such that it falls within the “lock” range of the VCSO.

FREQUENCY TRANSLATION PLL Product Data Sheet Serial Programming of M and N Dividers If S_LOAD is held HIGH, any S_DATA input is passed transparently (directly) to the M and N dividers on each rising edge of S_CLOCK. The M2004-01/-11 is serially programmed with S_DATA, S_CLOCK, and S_LOAD. See Figure 4, Serial Configuration Timing Diagram, below. The data is latched on the falling edge transition of the S_LOAD input (at point “c” in the timing diagram). With S_LOAD set LOW, the serially programmed values remain in the M and N dividers, unaffected by any serial pin input. Serial input mode is enabled when nP_LOAD is HIGH and S_LOAD is LOW (at point “a” in the the timing diagram, Figure 4). Data on the S_DATA input pin is serially loaded into the configuration shift register with each rising edge of the S_CLOCK input. (The T1 bit is input first, M0 last.) See Table 7, Pin Configuration & Serial Programming Functions, below. See also Figure 8, Times for M5:0 and N1:0, on pg. 9. When the shift register is full, its entire contents is loaded in parallel into the M and N dividers. This occurs on the rising edge of the S_LOAD input (at point “b” in the timing diagram). This load is transparent; the dividers immediately contain the serially programmed values.

FREQUENCY TRANSLATION PLL Product Data Sheet Hitless Switching and Phase Build-out * A proprietary automatic Hitless Switching (HS) function is included in the M2004-11. The HS function provides SONET/SDH MTIE and TDEV compliance during a reference clock reselection using the internal mux or when using an external mux (through detection of the resulting phase transient).** A Phase Build-out (PBO) function is also incorporated to absorb most of the phase change in the reference clock input. The combined HS/PBO function is armed after the device locks to the input clock reference. Once armed, HS/PBO is triggered by either: When the PLL locks to within 2 ns of the input clock phase, the PLL returns to normal loop bandwidth and the HS/PBO function is re-armed. External Loop Filter To provide stable PLL operation, and thereby a low jitter output clock, the M2004-01/-11 requires the use of an external loop filter components. These are connected to the provided filter pins (see Figure 5). Due to the differential signal path design, the implementation consists of two identical complementary RC filters as shown in Figure 5, below. • Changing REF_SEL to switch the input reference clock. • Detection at the phase detector of an input phase RLOOP CPOST transient beyond 4 ns. Once triggered, the HS function narrows loop bandwidth to control MTIE during locking to the new input phase. With proper configuration of the external loop filter, the output clocks will comply with MTIE and TDEV specifications for GR-253 (SONET) and ITU G.813 (SDH) during input reference clock changes. The Phase Build-out (PBO) function enables the PLL to absorb most of the phase change of the input clock. The PBO function selects a new VCSO clock edge for the phase detector feedback clock, selecting the edge closest in phase to the new input clock phase. This reduces re-lock time, the generation of wander, and extra output clock cycles. Note *: The M2004-01 does not include HS/PBO. Note **:Transient-triggered HS/PBO is not suitable for use with an unstable reference clock that would induce phase jitter beyond 2 ns at the phase detector (e.g., Stratum DPLL clock sources and unstable recovered network clocks intended for loop timing configuration). Therefore, the M2004-11 also offers the internal mux-triggered HS/PBO capability.
