Table 6 Pin Description Pin No. 66 65 39 40 47 48 73 Pin Name RSDP RSDN LOST LOST LOSE LOSE* TLPB Type I_ECL I_TTL I_TTL I_ECL Description Received serial data (RSDP/RSDN) are the differential input of 622 Mbps Rx bit stream. Loss of signal (LOST/LOST, LOSE/LOSE) indicate that RSDP/RSDN dosen't exist in order to prevent the PLL from runaway. RSDP/RSDN are masked and RxPLL goes training mode when LOST=H and LOST=L and LOSE/LOSE=H/L. Terminal loop back (TLPB) switch the RxPLL input to the loop backed signal form P/S converter when it's Low. Clock data recovery in lock (CDRLK) indicate that RxPLL is lock to Rx bit stream. It's active-high. Reference clock output (REFCKO) is 622/N MHz clock made from the recovered clock by RxPLL. Received parallel clock (RPCLK) is 77.76 MHz clock made from the recovered clock by RxPLL. It provides timing of RPD <7..0> and FP. Received parallel data (RPD <7..0>) are the bus of 77.76 Mbps Rx byte stream. RPD7 is the first bit received, RPD0 is the last. They should be latched on the rising edge of RPCLK. Frame position (FP) indicate the 3rd A2 byte in ATM frame header. It is active-high signal. Out of frame (OOF) enable the frame detector to find A1/A1/A1/A2/A2/A2 stream in RSDP/RSDN, output the flag to FP and establish the boundary when it's High. The frame detector dosen't output flag or re-establish the byte boundary when it's low. Reference clock input (REFCKI) is the 622/N MHz clock for transmitting clock source. TxPLL multiply it by N to generate the transmitting clock. It's also used for RxPLL training when loss of signal. Transmitting parallel clock (TPCLK) is 77.76 MHz clock made from the transmitting clock by the divider. It provides timing of TPD <7..0>. Transmitting parallel data (TPD <7..0>) are the bus of 77.76 Mbps Tx byte stream. TPD7 is the first bit transmitting, TPD0 is the last. They are latched on the rising edge of TPCLK when TPDLC=High. The latch timing is adjustable when TPDLC=Low by DLY <1, 0>. --6-- Equivalent circuit (c) (a) (a) (c)

Transmitting serial data (TSDP/TSDN) are the differential output of 622 Mbps Tx bit stream. Facility loop back (FLPB) enable the direct loop back from RSDP/RSDN to TSDP/TSDN when it's Low.

Transmitting parallel data (TPD<7..0>) are the bus of 77.76 Mbps Tx byte stream. TPD is converted into output-serial-data by P/S converter. Timing between TPCLK and TPD<7..0> is able to adjust by another inputs (TPDLC, DLY0, DLY1). This timing has 5 kinds ; DLY0, DLY1, DLY3, DLY5, DLY7. Timing of TPD for TPCLK (set up, hold time) is shown in Fig. 5 and Table 11.

2. Receiver Received parallel clock (RPCLK) is 77.76 MHz clock extracted from the recovered data by RxPLL. It provides timing of RPD<7..0> and FP. Received parallel data (RPD<7..0>) are the bus of 77.76 Mbps Rx byte stream. Input-serial-data is converted into RPD by S/P converter with RPCLK. When OOF is set "High", frame position (FP) indicate the 3rd A2 byte in ATM frame header. FP is active high signal which is detected by frame-detector, and width of active high signal is 1 byte. Timing of RPD and FP for RPCLK are shown in Fig. 5. And bounds of "OOF=1" for enable FP detection is shown in Fig. 6.

Notes on Operation 1. External Components PLLs CXB1590Q is the transceiver. It has the clock synthesizer for the transmitter and the clock recovery circuit for the receiver. (1) Clock Synthesizer CXB1590Q has the internal clock synthesizer based on PLL, which locks to REFCKI and generates bit rate clock frequency. It needs external loop filter and a resistor which determines the free-run frequency of VCO. Typical values of external components are indicated below. To minimize temperature dependency in VCO frequency, C1 should be a capacitor with less temperature coefficient.

It needs external loop filter and the resistor which determines the current of the charge pump. Typical values of external components are indicated below. There are two-sets recommended values ; (1) the one is to minimization jitter generation, (2) the another is to be satisfied the template (STM-4, OC-12) in jitter transfer measurement. To minimize temperature dependency in VCO frequency, C2 should be a capacitor with less temperature coefficient.
