7 / 10 page 4-171 CD22354A, CD22357A Hold Time from 3rd Period of Bit Clock Low to Frame Sync (FSX or FSR) tHBFI Long Frame Sync Pulse (from 3 to 8-Bit Clock Periods Long) 100 - - ns Minimum Width of the Frame Sync Pulse (Low Level) tWFL 64K Bit/s Operating Mode 160 - - ns NOTE: 1. For short frame sync timing, FSX and FSR must go high while their respective bit clocks are high. Pin Descriptions PIN NO. SYMBOL DESCRIPTION 1 V- Negative power supply, V- = -5V ±5%. 2 GND Analog and digital ground. All signals referenced to this pin. 3VFRO Analog output of RECEIVE FILTER. 4 V+ Positive power supply, V+ = 5V ±5%. 5FSR Receive Frame Sync Pulse which enables BCLKR to shift PCM data into DR. FSR is an 8kHz PULSE TRAIN. 6DR Receive Data Input. PCM data is shifted into DR following the FSR leading edge. 7 BCLKR/CLK- SEL The Receive Bit Clock, which shifts data into DR after the frame sync leading edge, may vary from 64kHz to 2.048MHz. Alternatively, the leading edge may be a logic input which selects either 1.536MHz/ 1.544MHz or 2.048MHz for Master Clock in synchronous mode and BCLKX is used for both transmit and receive directions. 8 MCLKR/PDN Receive Master Clock. Must be 1.536MHz, 1.544MHz or 2.048MHz. May be asynchronous with MCLKX, but best performance is realized from synchronous operation. When this pin is continuously connected low, MCLKX is selected for all internal timing. When this pin is continuously connected high, the device is powered down. 9 MCLKX Transmit Master Clock. Must be 1.536MHz, 1.544MHz or 2.048MHz. May be asynchronous with MCLKR, but best performance is realized from synchronous operation. 10 BCLKX The Bit Clock which shifts out the PCM Data on DX. May vary from 64kHz to 2.048MHz, but must be syn- chronous with MCLKX. 11 DX The THREE-STATE PCM Data Output which is enabled by FSX. 12 FSX Transmit Frame Sync Pulse input which enables BCLKX to shift out the data on DX. FSX is an 8kHz PULSE TRAIN. 13 TSX Open drain output which pulses low during the encoder time slot. 14 GSX Transmit gain adjust. 15 VFXI- Inverting input of the transmit input amplifier. 16 VFXI+ Non-inverting input of the transmit input amplifier.
